Thread: How to test something using ROLLBACK TRANSACTION
Coming from MS SQL server, if I ever change anything vital on a production system, or do any kind of major hackery on my own, I wrap it in a transaction first: BEGIN TRANSACTION; DELETE FROM vital_information WHERE primary_key = 10; ROLLBACK TRANSACTION; I then make sure that the result comes back and says 1 row(s) modified or something equally reassuring. I have horror stories where DBAs fat-fingered something and deleted data. But when I do this in pgadmin3, I get a dissatisfying result: Query returned successfully with no result in 15 ms. This response isn't wrong really... but it is not what I was hoping for. Any way to get the result of the commands that were inside the transaction?

Here's what I get from inside psql: smarlowe=# begin; BEGIN smarlowe=# delete from test where i between 4 and 6; DELETE 3 smarlowe=# rollback; ROLLBACK

Once your hooked, it is hard to use anything else. :o) -- Regards, Richard Broersma Jr. Visit the Los Angeles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug
