The following seems a little strange (in 7.02/Linux): zzz=# create table t1(f1 integer); zzz=# create temporary table t2(f1 integer, f2 integer); zzz=# Update t1 Set f1 = (select x.junk from t2 x where x.junk2 = t1.f1); ERROR: Unable to locate type name 't2' in catalog zzz=# drop table t2; zzz=# create table t2(f1 integer, f2 integer); zzz=# Update t1 Set f1 = (select x.junk from t2 x where x.junk2 = t1.f1); ERROR: No such attribute or function 'junk' ie. I get different errors for a temporary table... ---------------------------------------------------------------- Philip Warner | __---_____ Albatross Consulting Pty.
