Hi All,

I know this is a very small problem...but as I am new to forms,
hence I am unable to resolve this issue.

I want to update records in a table thorugh forms 6i.

For this I wrote the code in "when-button-pressed" trigger:

update ibt_books_category
set book_category = :IBC.book_category
where sub_category = :IBC.sub_category;

Here
ibt_books_category -> table name
sub_category ->column name (primary key)
book_category -> column name
IBC -> data block name
book_category -> item name
sub_category -> item name

Now when I press this button...nothing happens.. but when I close
the form..I get a message "do you want to save changes you made"
when I press OK button, it gives me error "Unable to insert record"
I don't know why this SQL command is not working in form's trigger.

Please help

Thanks

Hi,

The update won't take place until you issue a commit, which is why you are getting the message when you close the form, as Oracle tries to perform the uncommited transactions.

Try doing a commit after your update statement and add some error trapping to see why it can't insert the record.

Hope this helps

Hi P,

You see in you base block,

1)the properties of the item you are updating is it yes/no.
2)check if the the where is correct or not.
3)in your primary key make sure you are not violating primary
key constraint.

Bye
Ashu
