        幾個MySql的筆試題

          Which will be faster out of these two queries – one with OR or one with IN?

          Where does MyISAM cache table records?

          Which will be faster out of queries with explicit INNER JOIN and implicit one?

          Is InnoDB faster/better than MyISAM?

          Is CHAR faster than VARCHAR?

          Is VARCHAR(80) faster than VARCHAR(255)?

          Are there performance issues when joining tables from different storage engines?

        幾個MySql的筆試題

          If I change a derived table to a view, will performance increase?

          If I see Using temporary; Using filesort” in the Extra column of EXPLAIN output, does that mean a temporary table is created on disk?

          Is it possible to do a FULL OUTER JOIN in MySQL?
