Hello all. I'd like to write a query does a set subtraction A - B, but A is is a set of constants that I need to provide in the query as immediate values. I thought of something like
select a from (1,2,3.4) except select col_name from table; but I don't know the syntax to specify my set of constants. I thought of doing select 1 union select 2 union select 3 union ... except ... but I figure there must be a better way. The size of the set would be anywhere between 1 and about 5 or 6 elements. Is there a better way to do this? Thanks. Luca ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
