Thread: Triggers: FROM Inserted

Triggers: FROM Inserted

Hi

I am trying to migrate an application from MS SQL Server to Postgres.  In MS SQL triggers I have been used to declaring variables inserted into a table using the syntax 'SELECT . . . FROM Inserted'.  Can anyone tell me if it is possible to use the same syntax (ie FROM Inserted) in Postgres?  If not, is there an alternative?

Thanks.

No.

Yes ;-)

You can use NEW and OLD - variables. Read more about this:
