Cool SQL functions
Where can I find a site that explains all the SQL functions. I already know all the basic Selects, Joins... I'm looking for real useful stuff. For instance addition, concatonation, tops, sums...
Your Lord and Master, Foamy
SQL doesn't have functions. Each Database system implements their own functions for use within queries.
I think the basic math functions are standard SQL, e.g.
+, -, *, /
SUM, COUNT, MAX, MIN, AVG
Google is your friend, this is what I found immediately on searching for 'SQL Functions'
