Question

I am trying to convert a big list of SQL statements into a PostgreSQL stored procedure that uses a variable, one that should be populated from the result of one SELECT.

If you want to see what has to be run, you can check it here

As far as I know PostgreSQL does not allow use to use variables inside stored procedures that are using SQL language, so I’m looking for solutions that would require a minimal number of changes.

Answer 1

It’s much easier after you find the right syntax:

Here is the procedure definition for plpgsql language:

DECLARE myvar integer;
BEGIN
SELECT INTO myvar FROM ...;
-- use myvar
END;
