The only way I've found to do this is to use an external function, like this:
CLOSE DATABASES ALL *!* Source tables have 100 rows of random integers USE colmin1.dbf USE colmin2.dbf IN 0 USE colmin3.dbf IN 0 USE colmin4.dbf IN 0 CREATE CURSOR cout (f1 I, f2 I, f3 I, f4 I, minv I) INSERT INTO cout ; SELECT c1.f1, c2.f2, c3.f3, c4.f4, ; MinCol(c1.f1, c2.f2, c3.f3, c4.f4) As minv FROM colmin1 c1 ; JOIN colmin2 c2 ON c1.pk = c2.pk ; JOIN colmin3 c3 ON c1.pk = c3.pk ; JOIN colmin4 c4 ON c1.pk = c4.pk FUNCTION MinCol(n1, n2, n3, n4) As Integer RETURN CAST(MIN(n1,n2,n3,n4) As I) ENDFUNC I'd be interested to see another way of doing this.
