Informix sql update command error 746
I tried to update the field "contract_id" in the table
"contract_scan_image". However, the update was failed and an error "746:
Field contract_id and type of contract_scan_image cannot be updated!" was
shown.
My sql command is:
update contract_scan_image
set contract_id = '14864730'
where contract_id = '1486473'
and type = 'RM'
and account = '00193400944'
Anyone knows what happened and how to fix it?
Thank you.
