Hi:
I tried the following: CREATE TABLE x( a NUMERIC(5,0), b VARCHAR(5) );
CREATE TABLE y( a INTEGER, b VARCHAR(5) );
INSERT INTO x(b) VALUES ('LUDZ'); INSERT INTO y(b) VALUES ('TEST');
SELECT x.b,y.b FROM x,y WHERE x.a=y.a returns zero rows.
However: SELECT b FROM x WHERE a IS NULL returns 'LUDZ' SELECT b from y WHERE a IS NULL returns 'TEST'
I also tried SELECT x.b,y.b FROM x,y WHERE x.a = CAST(y.a AS INTEGER);
But it also returns zero rows.
Thank you in advance,
ludwig.
