Please find attached my form to this email. I attempted to assign the department name to non-database text_item4 in the when-validate-item trigger, but unfortunately, it was unsuccessful. Below is the code I used in the when-validate-item trigger. I explored all options including override, before, after, and with query, however, none of them yielded any results.

when-validate-item trigger code

begin

select DEPARTMENT_NAME into :employees.text_item4 from DEPARTMENTS where DEPARTMENT_ID=:employees.DEPARTMENT_ID;

end ;

see my form

Dear please use

select DEPARTMENT_NAME into :employees.text_item4 from DEPARTMENTS where DEPARTMENT_ID=:employees.DEPARTMENT_ID;
end ;


In Key_next_item:
Begin
select DEPARTMENT_NAME into :employees.text_item4  from  DEPARTMENTS where DEPARTMENT_ID=:employees.DEPARTMENT_ID;
next_item;
end ;

@fahim, along with the WHEN-VALIDATE-ITEM trigger, create POST-QUERY (using the same code as in the WVI trigger).

@shahzad, KEY-NEXT-ITEM is pretty much useless. It won't even fire if you navigate between items using a mouse. We did use it back in Forms 3.0 (or older), that's true, but that was 20-30 years ago.
