[GENERAL] Rules and conditions

[George Silva]

Hello guys,

I can't seem to understand why a simples if is not working on the
creation of rules.

I tried both ways (am i missing something?):

Take a look:

CREATE OR REPLACE RULE instead_update AS ON UPDATE TO foo
DO INSTEAD
(
        IF exists(SELECT 1 FROM versioning.foo_version_1 WHERE oid = new.oid)
= TRUE THEN
                UPDATE versioning.foo_version_1 SET
                        oid = new.oid,
                        att1 = new.att1,
                        att2 = new.att2,
                        the_geom = new.the_geom,
                        status = 'UPDATE'
                WHERE oid = new.oid;
        ELSE
                INSERT INTO versioning.foo_version_1 VALUES (NEW.*,'UPDATE');
        END IF;
)

Any toughts?

Thanks
