Обсуждение: getting oid of an INSERT automatically
Hello all,
In pgplsql, is there any way to get the oid that is returned from an INSERT statement, without
doing a 'follow-up' SELECT for the oid?
failing that, is this possible in jdbc, odbc or DBI?
Thanks,
jb

From the Programmers' Guide (PL/pgSQL section): 23.5.5. Obtaining result status GET DIAGNOSTICS variable = item [ , ... ] ; This command allows retrieval ofsystem status indicators. Each item is a keyword identifying a state value to be assigned to the specified variable(which should be of the right data type to receive it). The currently available status items are ROW_COUNT, the number of rows processed by the last SQL query sent down to the SQL engine; and RESULT_OID, the Oid of the last rowinserted by the most recent SQL query. Note that RESULT_OID is only useful after an INSERT query. -- Oliver Elphick Oliver.Elphick@lfix.co.uk Isle of Wight, UK http://www.lfix.co.uk/oliver GPG: 1024D/3E1D0C1C: CA12 09E0 E8D5 8870 5839 932A 614D 4C34 3E1D 0C1C ======================================== "Ye lust, and have not; ye kill, and desire to have, and cannot obtain; yefight and war, yet ye have not, because ye ask not."

Gee, you'd kinda think I could have read half-a-page down from where I had been looking. I'm an idiot.
