Re: Can I User @@error of MS SQL in postgresql

PostgreSQL is much more strict about error handling.  MSSQLServer will continue merrily along without interrupting the
procedureor affecting the in-progress transaction if errors occur.  It is up to you to catch them and decide how to
handlethem.  PGSQL will ignore all further queries and roll back the transaction automatically if any errors are
returnedfrom a query.  In other words, you don't have to worry about it.  If there are cases where the action failing
wouldbe OK, you need to test for those cases (i.e. duplicate key already exists) before the action.  Keep in mind that
thosechecks will not always be valid given the status of other transactions and your isolation level. 

Isn't this fun?

I have a plpgsql function to insert a record into a table.  In MS SQL, I can user @@error to check the insert action is
completedor not.  What can I do in postgresql? 
Thanks a lot.
