1.	Which system variable when set to 1, makes all temporary tables to get stored on disk rather than in memory?(a) basedir(b) back_log(c) big_tables(d) bind_address
Answer» Correct answer is (c) big_tables Easy explanation: The variable ‘big_tables’ if set to 1, all temporary tables are stored on disk rather than in memory. This is a little slower but the error ‘The table tbl_name is full’ does not occur for SELECT operations that require a large temporary table.
