Delete Cursor: What To Use In Select Clause?

I am using a SELECT ... FOR UPDATE cursor to perform DELETE ... WHERE CURRENT statements. Since I am not interested in the contents of the records I am deleting, I don't really need anything in the select clause of the SELECT statement, but it seems that syntax requires me to put something there. I'm currently just using the serial not null primary key field. Does it matter what goes there? I know that with the NOT EXISTS subquery, the manual says that you might as well use SELECT * "because the existence of the whole row is tested; specific column values are not tested" [Syntax v7.1 1-529]. (Is this true?) I apologize if this is a newbie question; I didn't see it in the FAQ. -- Alexander J. Oss Computer Systems Manager Films for the Humanities & Sciences
