I was just at a talk on relational database query optimization using
the technique of "Magic Sets".  I was wondering what RDBMSes use any
form of query optimization (i myself have been bitten quite a number
of times by not writing my SQL query the right way)? Is it still on
the user of SQL to format the query in the right way to get the answer
the fastest way?
