Moving From Top To Bottom in Detailed Block in Oracle Forms

Suppose you want to scan a tabular grid block (loop through all records in detail block) from top to bottom in Oracle forms. You can do this task by using :system.last_record system variable to determine whether it is last record in a block and then exit.

 

Example:

 

Begin

   go_block('yourblock');

   --- then move to first record

   first_record;

   Loop

      --- do some processing

      null;

      if :system.last_record = 'TRUE' then

         exit;

      End if;

      next_record;

   End Loop;

   --- after exiting move to top

   first_record;

End;
