Hello everyone.
In order to build some dynamic queries (EXECUTE under PL/PgSQL)
I'm taking in consideration to use the INTERSECT operator in order
to split a WHERE-condition in a static one and a dynamic one to be
built at runtime.
Instead of
SELECT * FROM joinedtables WHERE static_cond AND dynamic_cond;
I could use:
SELECT * FROM joinedtables WHERE static_cond
INTERSECT
SELECT * FROM joinedtables WHERE dynamic_cond
I'm wondering what'd be the difference in efficiency between these
two queries.
Is there any advise?
Many thanks in advance.
