     GO_ITEM('JOB_CARD_MAIN.BRANCH_CODE');
     set_block_property('job_card_main',default_where,'job_no='||chr(39)||:job_card_main.job_no||chr(39));

     insert into da.mylog(username,tname,mdate,oper) values(user(),'Job Creation',sysdate,'S');
     commit;
end;

Answer 1

Which trigger do you have this code in? I'm guessing it is a Key-ListVal trigger.
Have you tested the WHE RE clause in SQL*Plus to ensure it returns a record set? Most likely, the query returns no rows which could explain why the block is empty. Also, why are you clearing the entire Form instead of just the JOB_CARD_MAIN data block? Perhaps you should try:
Go_Block('JOB_CARD_MAIN');
Clear_Block(NO_VALIDATE);Also, the EXECUTE_QUERY built-in does not have a NO_VALIDATE parameter. It only supports the following parameters:
ALL_RECORDS
FOR_UPDATE
or the combination of the two (ALL_RECORDS,FOR_UPDATE). It also allows you to set the Locking mechinism by passing the parameter NO_WAIT.
Just a suggestion, try your query in SQL*Plus to make sure it produces a record set and Comment out all the extra stuff in your code and only keep the SHOW_LOV, CLEAR_BLOCK, SET_BLOCK_PROPERTY and EXECUTE_QUERY to see if a row is returned. If yes, then add the rest of your code back one line at a time.
Hope this helps,
