I think what you are looking for is a parametrized view, but that doesn't exist. One obvious solution is to put this into a function, but that might not have the best performance, depending on what sort of contexts you want to use the view in. Another option would be using prepared statements. -- Peter Eisentraut http://developer.postgresql.org/~petere/
