Debug SQL in pgAdmin when SQL contains variables

Question

In SQL Server I could copy sql code out of an application and paste it into SSMS, declare & assign vars that exist in the sql and run. yay great debugging scenario.

Answer 1

I would give a shot at writing a SQL function that wraps your query. It can be something as simple as

CREATE OR REPLACE FUNCTION my_function(integer, integer) 
RETURNS integer
AS
$$
    SELECT $1 + $2;
$$ 
LANGUAGE SQL;

SELECT my_function(1, 2);

I would do this instead of a PREPARE since it will be simpler to update it. Depending on how complex the function is, you might want to also look at some of the other PL's in Postgres.
