What's the most efficient way in MySQL to test whether a table exists?
I'm trying to remove/reduce wasteful queries in my application to improve the speed. One query I have checks to see whether a table exists. It does this by trying to select the primary key field from the table and adds 'Limit 1' to the end of the query so that it doesn't select the whole table.
My question is this: is the most efficient way to determine whether a table exists or is there an even more efficient way?
