Обсуждение: pgsql procedures??
What we are trying to figure out is if postgresql supports
returning multiple result sets from a stored procedure (psql
function?)
For example in MSSQL's Northwind database you can create the
following stored procedure:
<mssql-proc>
CREATE PROCEDURE "test"
AS
SELECT * FROM Orders
SELECT * FROM Customers
GO
</mssql-proc>
This would return two datasets from the procedure.
We are unsure as to how to map this in to a pgsql equivalent.

But it can if you switch to one of the other languages like plpgsql, which isn't terribly complicated but does require the language to be installed in the database. -- Nigel J. Andrews

You might be able to fake it by returning multiple cursors, however.
