Later versions do allow anonymous blocks, also known as DO statements that allow you to execute some code to allow decision making like that. So the Oracle example is very similar code in PostgreSQL, except that you can't issue ROLLBACK and COMMIT. How do you do that?But then you don't need to because you can do a conditional error or drop through to a commit. Regards |
