Did you try creating a view with that select statement, then just selecting from the view? I don't know if there is a restriction on using a function like that in a view definition or not.

I use it in select statements: ohc=> SELECT sample_id, is_wipe_positive(tblleadwipe.sample_id) AS positive FROM tblleadwipe WHERE hud_building_id IS NOT NULL; sample_id | positive -----------+---------- 73 | f 81 | t (2 rows) I see that I cannot change my WHERE statement to WHERE positive = 't' because the column positive does not exist. Now I am looking for the best way to return all records that are found positive or negative using a query. Can anyone offer any guidance to how I can return all the positives (or negatvies)? Or do I need to write another function that does that? -- Robert ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
