getting checked value from checkbox thats taking data from database
getting checked value from checkbox thats taking data from database
I have problem to get to the checked value in checkbox. I have first query
that is taking names of the tables in database and second query that is
taking names of the columns of that tables. Names of the columns are
displayed in a checkbox, but i have problem to take that values from the
checkbox. I know I should use $_POST['kolona'] but somehow that variable
its not recognized:
if(mysqli_connect_errno())
{
echo "Error: Greška u konekciji";
exit;
}
$sql1 = "SHOW TABLES FROM db_baza";
$result1 = mysql_query($sql1);
if (!$result1)
{
echo "DB Error, could not list tables\n";
echo 'MySQL Error: ' . mysql_error();
exit;
}
while ($row1 = mysql_fetch_row($result1))
{
echo "<div id='blok'
style='width:200px;height:200px;background-color:red;margin:20px;float:left;'>{$row1[0]}"."</br>";
$tablename=$row1[0];
$sql2="SELECT column_name FROM information_schema.columns WHERE
table_name = '{$tablename}'";
$result2= mysql_query($sql2);
while($row2=mysql_fetch_row($result2))
echo "<form id='forma1' action='' method='POST'><input type='checkbox'
name='kolona[]' value='{$row2[0]}' />{$row2[0]}</br>";
echo "<input type='submit' name='submit' value='{$tablename}'/></form>";
echo "</div>";
}
if(isset($_POST['submit']))
if(isset($_POST['kolona'])
echo 1;
?>
So, I am just trying to echo number one, i will need it for other stuff
but just for the example.

Why can I not pass to_lower_copy directly to transform instead of wrapping it in a lambda?
Why can I not pass to_lower_copy directly to transform instead of wrapping
it in a lambda?
I'm trying to use boost::to_lower_copy and std::transform to lower-case a
bunch of strings. As below, Variant 1, using a lamdba works; Variant 2
also works demonstrating that that's the right template-overload the
compiler picks. But the lambda is silly – all it does is forward the
single argument along to boost::to_lower_copy. But Variant 3, using the
function template directly doesn't compile, even if I instantiate it. What
am I missing?
I have clang version 3.3 (tags/RELEASE_33/rc3), using
libstdc++-4.8.1-1.fc19.i686 and boost-1.53.0-14.fc19.i686.
vector<string> strings = {"Foo", "Bar"};
vector<string> lower_cased_strings;
transform(
strings.begin(),
strings.end(),
inserter(lower_cased_strings, lower_cased_strings.end()),
// Variant 1
// [](const string &word) {
// return boost::to_lower_copy(word);
// }
// Variant 2
// [](const string &word) {
// return boost::to_lower_copy<string>(word);
// }
// Variant 3
boost::to_lower_copy<string>
);

Where is disk buffer cache situated
Where is disk buffer cache situated
I have read that The buffer cache interfaces with block devices, and
caches recently used meta-data disk blocks. The Linux kernel reads file
data through the buffer cache, but keeps the data in the page cache for
reuse on future reads.
I know that page cache is situated at main memory. Whether its true with
buffer cache also?
If buffer cache is in main memory, how access is made to it. Whether any
mechanism like paging is used for accessing buffer cache?

I am new to C#. I have a parent class declared:
class PmdTable

and I have a child class
class PmdSdStageCfg : PmdTable

Now it complains if I do like:
List<OracleObject.PmdTable> instanceList = new List<PmdSdStageCfg>();
The error says"Cannot implicityly convert type
'System.Collections.Generic.List' to 'System.Collection.Generics.List'".
Since PmdTable is the parent class. Why this does not work?

How do I enable SR-IOV for Mellanox ConnectX-3 Ubuntu 12.04.3?
How do I enable SR-IOV for Mellanox ConnectX-3 Ubuntu 12.04.3?
I have a Supermicro 2027TR-HTFRF server that I'm using as a xen server.
What I'm wanting to do is get SR-IOV operating for the Connectx-3 card so
that I can expose Infiniband to virtual machines.
Following this recipe I managed to get the I350 Ethernet to expose the VF's.
Adding /etc/modprobe.d/mlx4_core.conf containing
options max_vfs=4
Didn't create the virtual functions for the mellanox device despite the
fact that this is a valid parameter to the mlx4_core module. i.e.
The error I get is
mlx4_core: `4' invalid for parameter `max_vfs'
I also tried a value of 1 to which I got a similar error
mlx4_core: `1' invalid for parameter `max_vfs'
Output from lspci -v
06:00.0 Network controller: Mellanox Technologies MT27500 Family [ConnectX-3]
Subsystem: Mellanox Technologies Device 0051

So it would seem that SR-IOV is not available.
I then discovered this thread: http://community.mellanox.com/thread/1073
But I'm using ubuntu 12.04.
Next I installed mstflint using apt-get.
Then I identified what type of card it is.
mstflint -d 06:00.0 q
Unfortunately mstflint crashes.

At this point I'm somewhat stuck.
Update: I managed to obtain a firmware update from SuperMicro which has
SR-IOV enabled.
Also I needed to set options max_vfs= to options num_vfs=. It seems the
named parameter is slightly different. This was enough to get it working
under Ubuntu.
Installing the firmware I used this method: http://www.panticz.de/mellanox
But with the addition that I had to call insmod on each module before
calling mst start. Modprobe didn't work.
I have a Supermicro 2027TR-HTFRF server that I'm using as a xen server.
What I'm wanting to do is get SR-IOV operating for the Connectx-3 card so
that I can expose Infiniband to virtual machines.
Following this recipe I managed to get the I350 Ethernet to expose the VF's.
Adding /etc/modprobe.d/mlx4_core.conf containing
options max_vfs=4
Didn't create the virtual functions for the mellanox device despite the
fact that this is a valid parameter to the mlx4_core module. i.e.
The error I get is
mlx4_core: `4' invalid for parameter `max_vfs'
I also tried a value of 1 to which I got a similar error
mlx4_core: `1' invalid for parameter `max_vfs'
Output from lspci -v

So it would seem that SR-IOV is not available.
I then discovered this thread: http://community.mellanox.com/thread/1073
But I'm using ubuntu 12.04.
Next I installed mstflint using apt-get.
Then I identified what type of card it is.
mstflint -d 06:00.0 q
Unfortunately mstflint crashes.
Warning: memory access to device 06:00.0 failed: Input/output error.
Warning: Fallback on IO: much slower, and unsafe if device in use.

Please help me. I'm confused what is what: GrantedAuthority, UserDetails,
User and how they work with xml configuration of Spring Security.
Thanks.
Spring + Hibernate + UserDetailService
I just started to learn Spring Security and have some trouble. I want to
configure User login on page with password and username which stored in
database during registration. I use Hibernate.

MVVM Light Portable Class Library Navigation
MVVM Light Portable Class Library Navigation
I am making a Windows Phone 8 app using the MVVM architecture and a
portable class library. I am currently using MVVM light messages to
navigate to a new page. Is there a different approach that I can use
instead of messages because I always have to put code in the code behind.

Within "with" binding div, I tried to bind 5 properties of a model to 2
different types of controls, namely textbox and label. However, only the
first property on the list is bound to two controls, the rest are only
bound to textbox:
<div data-bind="with: Object">
<input type= "text" data-bind="value: property1" /> <br />

Object is populated dynamically, meaning its properties are assigned
dynamically. In my view model, I have Object = ko.observable() . And once
user clicked some button, I have Object(createModel1()) executed, where
createModel1 returns a new Model1. Model1 has properties defined as
ko.observable.
I don't know whether this is not supposed to work or am I doing something
else wrong (barking at the wrong tree) Please help! Thank you!!!
Within "with" binding div, I tried to bind 5 properties of a model to 2
different types of controls, namely textbox and label. However, only the

form variables not passing to php
form variables not passing to php
I'm using php version 5.5.1 and Apache server if this information helps I
have a simple form and I'm trying to pass the form variable to php and
output the value. I am a beginner in php so please excuse me if this is
something obvious, I have tried to solve this myself with the almighty
google but wasn't successful. The html form code is as follows
<html>
<head>
<title>Form</title>
</head>
<body>
<form method="post" action="test1.php">
<input type="text" name="username">
<input type="submit">
</form>
</body>
</html>
Then the php to handle the form is:
<html>
<head>
<title>Form</title>
</head>
<body>
<?php
echo "<h1>Hello " . $_POST["username"] . "</h1>";
?>
</body>
</html>
The output I'm getting no matter what I type into the html form is , Hello
" . $_POST["username"] . ""; ?>
I don't know why it also outputs the ending semi colon and ending php tag
also, maybe this is evidence of what's going wrong here?
Any and all help is appreciated! Thank You.

How do I make an emualator for a certain device?
How do I make an emualator for a certain device?
So I'm trying to make a new emulator in "Virtual Devcice Manager" in
Eclipse. I want it to be the same as a certain device (same screen size,
same android version installed as it is by default on that device etc.).
The device I'm trying to "re-create" as an emulator is Sony Xperia Z. I
searched for the phone's specs and this is what I found:
Android 4.1
12.7cm (5") screen
I then tried to create a new virtual device in eclipse and I don't have
any of these options. The closest Android version that Eclipse lets you
use for Virtual device is 4.1.2 and the closest screen size is 5.1" WVGA
If I created a virtual device like this, would it be good? Would an
application that I ran on this virtual device behave the exact same way as
on actual Sony Xperia Z?

Precision timing using DateTime possible?
Precision timing using DateTime possible?
I would like to test the time required by certain methods and SQL queries
in my code. I've tried doing the following:
DateTime start = DateTime.Now;
//Do something
DateTime end = DateTime.Now;
TimeSpan ts = end - start;
int millis = ts.Milliseconds;
But I just don't feel that this is the right way of doing it. I often get
back a value of 1 for some methods and values like 200 for others, are
there any accurate ways to measure and record this kind of thing?

How to restrict foreign keys in Rails' update controller action?
How to restrict foreign keys in Rails' update controller action?
In my Rails app I have invoices which in turn can have many projects.
model:
class Invoice < ActiveRecord::Base
attr_accessible :project_id
end
controller:
class InvoicesController < ApplicationController
before_filter :authorized_user, :only => [ :show, :edit, :destroy ]
before_filter :authorized_project, :only => [ :create, :update ]
def create # safe
@invoice = @project.invoices.build(params[:invoice])
if @invoice.save
flash[:success] = "Invoice saved."
redirect_to edit_invoice_path(@invoice)
else
render :new
end
end
def update # not safe yet
if @invoice.update_attributes(params[:invoice])
flash[:success] = "Invoice updated."
redirect_to edit_invoice_path(@invoice)
else
render :edit
end
end
private
def authorized_user
@invoice = Invoice.find(params[:id])

end
def authorized_project
@project = Project.find(params[:invoice][:project_id])
redirect_to root_path unless current_user?(@project.user)
end
end
My biggest concern is that a malicious user might, one day, create an
invoice that belongs to the project of another user.
Now thanks to the help of some people on this board I managed to come up
with a before_filter that makes sure that this won't happen when a project
is created.
The problem is I don't understand how to apply this filter to the update
action as well.
Since the update action does not make use of Rails' build function, I
simply don't know how to get my @project in there.
Can anybody help?

$pages= new Paginator('10', 'p'); //create object

c++ : the game of life?
c++ : the game of life?
i really need your help and really fast. i've been working on this project
where i am supposed to create a simulation of conway's game of life.
A cell can only be in one of two states: alive or dead. There are two
kinds of cells: ConwayCells and FredkinCells.
Live ConwayCells are denoted with an asterisk, "*", and dead cells are
denoted with a period, "." A ConwayCell has 8 neighbours, if it's an
interior cell, 5 neighbours, if it's an edge cell, and 3 neighbours, if
it's a corner cell
ConwayCells do not have the notion of age, FredkinCells do. A
FredkinCells' age is initially zero and only increments by one if the cell
is alive and stays alive. Live FredkinCells are denoted with their age, if
their age is less than 10, otherwise denoted with a plus, "+", and dead
cells are denoted with a minus, "-". A FredkinCell has 4 neighbours, if
it's an interior cell, 3 neighbours, if it's an edge cell, and 2
neighbours, if it's a corner cell.
The rules for going from one generation to the next for ConwayCells are:
a dead cell becomes a live cell, if exactly 3 neighbours are alive
a live cell becomes a dead cell, if less than 2 or more than 3 neighbours
are alive
The rules for going from one generation to the next for FredkinCells are:
a dead cell becomes a live cell, if 1 or 3 neighbours are alive
a live cell becomes a dead cell, if 0, 2, or 4 neighbours are alive
I have to create 5 classes: *Cell class(abstract) from which two are
derived ConwayCell and FredkinCell where each of these cells knows how to
print itself, whether it is alive or not and how many neighbours are
alive. *Life class(abstract) from which two others are derived :
fredkinLife and conwayLife.the subclasses should have functions that keeps
track of the grid (2d dynamic array) and generation , that plays life ,
that evolves , and that prints itself.
And a LifeFactory class that would shoose between creating a fredkinLife
or a ConwayLife.
To push Life forward one generation (evolve), traverse the grid of cells,
only notice the live cells, and for each of them, visit the neighbours and
increment their respective neighbour counts. Remember that the two kinds
of cells have different definitions of neighbour. Traverse the grid a
second time, set the next state, and zero out the neighbour count.
Remember that the two kinds of cells have different rules for the next
state.
In a main program, you will read in initial board states from an input
file and iterate through several generations of the game of life.

basically what i am asking for is someone to check if my code is correct
and to help me implement gthe other functions in class Life (no code is
required) just detailed explanation
i really need your help and really fast. i've been working on this project
where i am supposed to create a simulation of conway's game of life.
A cell can only be in one of two states: alive or dead. There are two
kinds of cells: ConwayCells and FredkinCells.
Live ConwayCells are denoted with an asterisk, "*", and dead cells are
denoted with a period, "." A ConwayCell has 8 neighbours, if it's an
interior cell, 5 neighbours, if it's an edge cell, and 3 neighbours, if
it's a corner cell
ConwayCells do not have the notion of age, FredkinCells do. A
FredkinCells' age is initially zero and only increments by one if the cell
is alive and stays alive. Live FredkinCells are denoted with their age, if
their age is less than 10, otherwise denoted with a plus, "+", and dead
cells are denoted with a minus, "-". A FredkinCell has 4 neighbours, if
it's an interior cell, 3 neighbours, if it's an edge cell, and 2
neighbours, if it's a corner cell.
The rules for going from one generation to the next for ConwayCells are:
a dead cell becomes a live cell, if exactly 3 neighbours are alive
a live cell becomes a dead cell, if less than 2 or more than 3 neighbours
are alive
The rules for going from one generation to the next for FredkinCells are:
a dead cell becomes a live cell, if 1 or 3 neighbours are alive
a live cell becomes a dead cell, if 0, 2, or 4 neighbours are alive
I have to create 5 classes: *Cell class(abstract) from which two are
derived ConwayCell and FredkinCell where each of these cells knows how to
print itself, whether it is alive or not and how many neighbours are
alive. *Life class(abstract) from which two others are derived :
fredkinLife and conwayLife.the subclasses should have functions that keeps
track of the grid (2d dynamic array) and generation , that plays life ,
that evolves , and that prints itself.
And a LifeFactory class that would shoose between creating a fredkinLife
or a ConwayLife.
To push Life forward one generation (evolve), traverse the grid of cells,
only notice the live cells, and for each of them, visit the neighbours and
increment their respective neighbour counts. Remember that the two kinds
of cells have different definitions of neighbour. Traverse the grid a
second time, set the next state, and zero out the neighbour count.
Remember that the two kinds of cells have different rules for the next
state.
In a main program, you will read in initial board states from an input
file and iterate through several generations of the game of life.

author_name I got a error message. I'll try to translate the error message
from portuguese but I don't know if it is like that in english: "Undefined

The funny part is that the university search and order is working just
fine. And I can't see the diference between they.

I want to see if an object exists in the array above. And I have no idea
why its not working, here is my code to find the object:
jQuery.inArray("Apple", fruits["title"]); //this returns -1 why?
Any ideas how to search two dimentional array?

Network condition monitoring, in android native voip SDK
Network condition monitoring, in android native voip SDK
I have developed an android VOIP client using the native Android VOIP SDK,
I have been asked to display the status of the network during the active
phone call, e.g. The App says Expect good,bad or fair phone call in real
time while the user is talking, just like Skype or Viber.
Perhaps I could not find the solution myself because I presumed that Viber
or Skype implemented it from within their VOIP stack, While in the reality
It is just a separate software-networking function.

How to resolve a NameError in my 'rock, paper, scissors' function
How to resolve a NameError in my 'rock, paper, scissors' function
I just started programming in python 2.7.x. and had to put a programm for
rock, paper and scissors into a function. In the programm itself I asked
the user for an input and now I have to change it to just using parameters
only and using return instead of 'print'. Its a simple piece of code but I
just keep getting the NameError: name 'x' is not defined.
So I run the function into shell and then I type in: rps(rock, paper).
Some hints on how to resolve this or advice on my code would be great.
Here's the code.
def rps(player1, player2): if (player1 != 'rock' and player1 != 'scissors'
and player1 != 'paper'): return 'This is not a valid object selection'
if (player2 != 'rock' and
player2 != 'scissors' and
player2 != 'paper'):
return 'This is not a valid object selection'
if (player1 == 'rock' and
player2 == 'scissors'):
return 'Player 1 wins.'
if (player1 == 'rock' and
player2 == 'rock'):
return 'There is a tie.'
if (player1 == 'rock' and
player2 == 'paper'):
return 'Player 2 wins.'
if (player1 == 'scissors' and
player2 == 'scissors'):
return 'There is a tie.'
if (player1 == 'scissors' and
player2 == 'rock'):
return 'Player 2 wins.'
if (player1 == 'scissors' and

How to detect of tap gesture is from uiwebview or self.view?
How to detect of tap gesture is from uiwebview or self.view?
Hello everyone I have a uitapgesture on my view using the following code :

initWithTarget:self action:@selector(TAPGestureRecognizer)];
tap.numberOfTapsRequired=1;
tap.delegate = self;
[self.view addGestureRecognizer:tap];
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer
shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer
*)otherGestureRecognizer
{
return YES;
}
And I have a uiwebview as a subview in my UIview. The problem is that on
the uivewview HTML it had a onclick(); which in turn is calling the
tapgesture. Any help?

Jenkins - NUnit/MSTest Code Coverage Graph
Is it possible to produce a graph of code coverage v time in Jenkins for
NUnit/MSTest?
I can produce a code coverage report with OpenCover and ReportGenerator. I
would prefer to be able to visualise this with a graph. The NUnit plugin
only produces of a graph of tests run or test failures over time.
On a separate note, does anyone know how to get OpenCover to set the
%ERRORLEVEL% batch variable is a test fails during code coverage
calculation?

How to programmatically display HTML5 client-side form validation error bubbles?
How to programmatically display HTML5 client-side form validation error
bubbles?
I'm trying to use HTML5 client-side validation (i.e. inside a form), but
cannot see how to display the validation error bubbles programatically.
Consider the following:
<form id="myForm">
<input type="text" id="number" min="1" max="10" step="3" required>
</form>
If there is a canonical submit button (i.e <input type="submit">), and
there are validation errors, the user-agent will halt the submit and show
UI to the user:
But, if instead of a using a submit input, the user is clicking an anchor
that executes javascript (i.e. ASP.net Webforms):
<a href='javascript:SaveChanges()'>Save Quantity</a>
<script>
function SaveChanges()
{
var form = document.getElementById('myForm');
if (form === null) return;
if (!form.checkValidity())
{
//We reach here, but no UI is displayed
return;
}
form.submit();
</script>
The issue is that while
form.checkValidity();
does check the form's validity (returning false if it's not valid), it
does not trigger the UI displays.
And now we have our question. Submitting through
<input type="submit"> works (halts and shows UI)
<button type="submit> works (halts and shows UI)
form.submit doesn't work (doesn't halt; doesn't show UI)
form.checkValidity() doesn't work (doesn't show UI)

bubbles?
I'm trying to use HTML5 client-side validation (i.e. inside a form), but
cannot see how to display the validation error bubbles programatically.
Consider the following:
<form id="myForm">
<input type="text" id="number" min="1" max="10" step="3" required>
</form>
If there is a canonical submit button (i.e <input type="submit">), and
there are validation errors, the user-agent will halt the submit and show
UI to the user:
But, if instead of a using a submit input, the user is clicking an anchor
that executes javascript (i.e. ASP.net Webforms):
<a href='javascript:SaveChanges()'>Save Quantity</a>
<script>
function SaveChanges()
{
var form = document.getElementById('myForm');
if (form === null) return;
if (!form.checkValidity())
{
//We reach here, but no UI is displayed
return;
}
form.submit();
</script>

Is it possible to do an inline "else if"?
Is it possible to do an inline "else if"?
This is really unnecessary, but I'm curious... can you do an inline "else
if" much like you would do a standard inline if/then/else? A few minutes
of googling did not return an answer.
Example:
if (n == 1) {
alert("The variable is 1!")
} else {
alert("The variable is not 1!")
}
is the same as:
n == 1 ? alert("The variable is 1!") : alert("The variable is not 1!")
But is there a way to do this using similar syntax?
if (n == 1) {
alert("The variable is 1!")
} else if (n == 2) {
alert("The variable is 2!")
} else {
alert("The variable is not 1 or 2!")
}
I tried the following, but it did not seem to work:
n == 1 ? alert("The variable is 1!") : (n == 2 ? alert("The variable is
2!") : alert("The variable is not 1 or 2!"))

Javascript if value is in array else in next array
Javascript if value is in array else in next array
I have found a few posts on here with similar questions but not entirely
the same as what I am trying. I am currently using a simple if statement
that checks the data the user enters then checks to see if it starts with
a number of different values. I am doing this with the following:
var value = string;
var value = value.toLowerCase();
country = "NONE";
county = "NONE";
if (value.indexOf('ba1 ') == 0 || value.indexOf('ba2 ') == 0 ||
value.indexOf('ba3 ') == 0) { //CHECK AVON (MAINLAND UK) UK.AVON
country = "UK";
county = "UK.AVON";
}
I have about 20-30 different if, else statements that are basically
checking the post code entered and finding the county associated. However
some of these if statements are incredibly long so I would like to store
the values inside an array and then in the if statement simply check
value.indexOf() for each of the array values.
So in the above example I would have an array as follows for the statement:
var avon = new Array('ba1 ','ba 2','ba3 ');
then inside the indexOf() use each value
Would this be possible with minimal script or am I going to need to make a
function for this to work? I am ideally wanting to keep the array inside
the if statement instead of querying for each array value.
Edit:
just found a post on here mentioning the following JQuery:
$.inArray(value, array) am going to have a play around with this

Find the best solution for read file and call web service
Find the best solution for read file and call web service
I have a text file which has about 100,000 records of identifier.
I must read all of record, each record i do request to web service and
receive the result from web service, the result i write to another file.
I'm confuse between two solution: - Read identifier file to a list of
identifier, iterate this list, call web service, .... - Read identifier
line on each line, call web service, .....
Do you think what solution will be better ? program will do faster ?
Thanks for all.

Python module pseudo compiler idea.
Python module pseudo compiler idea.
Say I work for a python project, in folder myfolder/
it has a library file "Mylibrary.py" and a script file "myscript.py"
and in myscript.py I imported Mylibrary.py, is there a program such that
it will replace "import Mylibrary" by my library file literally and
replace all function call "Mylibrary.myfunction" by "myfunction"? It kind
of like "compile" multiple python scripts into one. Or this would be a
terrible solution
The reason is that I want to use myscript as an executable in other
folders without having to copy multiple files or making a package.

Create a list out of the output in loop
Create a list out of the output in loop
We are tasked to print out the values in the pascal triangle in this manner
(pascal 2)
(1 2 1)
(pascal 0)
(1)
I copied the code for the binomial thereom somewhere in the internet
defined as follows:
(defun choose(n k)
(labels ((prod-enum (s e)
(do ((i s (1+ i)) (r 1 (* i r))) ((> i e) r)))
(fact (n) (prod-enum 1 n)))
(/ (prod-enum (- (1+ n) k) n) (fact k))))
Now I'm trying to create a list out of the values here in my pascal function:
(defun pascal (start end)
(do ((i start (+ i 1)))
((> i end) )
(print (choose end i) ))
)
The function produces 1 2 1 NIL if I test it with (pascal 0 2). How can I
eliminate the NIL and create the list.

What are the orgins of the terms "parse" in java?
What are the orgins of the terms "parse" in java?
In java I noticed there are methods associated with conversion of strings
and those methods sometimes use the word "parse" in the name of the
method. For example the static method,
static int parseInt(String str)
is used to convert a string into int. My question is this. Is "parse"
short for another word? Is is just a random word or did it come from
somewhere else in some other context?

When can DECLARE EXIT HANDLER FOR SQLEXCEPTION ROLLBACK have an effect?
When can DECLARE EXIT HANDLER FOR SQLEXCEPTION ROLLBACK have an effect?
DECLARE EXIT HANDLER FOR SQLEXCEPTION ROLLBACK is "supposed" to be used
before a transaction, to explicitly set the value on failure.
However, the documentation states that this is more or less the default
behavior anyway?
If a condition occurs for which no handler has been declared, the action
taken depends on the condition class:
For SQLEXCEPTION conditions, the stored program terminates at the
statement that raised the condition, as if there were an EXIT handler. If
the program was called by another stored program, the calling program
handles the condition using the handler selection rules applied to its own
handlers.
But that means COMMIT is never called, so, same effect as having no handler.
I'm not sure how to interpret that. It sounds like the "obvious" thing to
do is exit the stored program, but if a calling program has handlers
telling to do otherwise - perhaps a DECLARE EXIT HANDLER FOR SQLEXCEPTION
CONTINUE - it's not clear to me whether the inside stored program
continues or not, or what the "handler selection rules" are in general.
If this (strange to me) interpretation is the case, then that means if
hypothetically a stored program could assume it was never called by
another stored program, the handler is extraneous, but it ensures
consistent behavior
