I have a Pl/Perlu function in which I have written an insert statement in tbl_xyz. If there's not foreign key in this table, insert works fine. As soon as i make one of its fields refer to tbl_abc i.e field a in tbl_xyz refering to field a in tbl_abc, insert fails. Now the problem is, I can't see the actual error, i mean the place where it fails. Is there any way by which I can include a few lines of code that would log any error in a file whenever the insert fails.
