Hi,Shouldn't the final command below cause a 'column "b" does not exist error'? create table update_test (a int, b int); create table supdate_test(x int, y int); insert into update_test values (20, 30); insert into supdate_test values (40, 50); select a, (select b from supdate_test) from update_test; a ?column? ---------- ------------------------- 20 30 Is the problem with the code in colNameToVar or maybe we should add checks in transformSubLink?
I don't think so...the columns of update_test are visible to the scalar subquery...that way you can use fields from 'a' to filter the subquery... select a, (select y from supdate_test where x = a) from update_test; merlin ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
