  1. Which system variable when set to 1, makes all temporary tables to get stored on disk rather than in memory?
    1. big_tables
    2. basedir
    3. bind_address
    4. back_log
    5. None of these
Correct Option: A

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.
