Notice
Please note, there can be an incorrect result given when running a query using LIMIT with an offset. See the following example:
CREATE TABLE t1(a BIGINT PRIMARY KEY AUTO_INCREMENT, b INT); INSERT random integers into t1 so total row count is greater than LIMIT argument. SELECT COUNT(*) FROM t1 GROUP BY a ORDER BY a LIMIT 5,10; +----------+ | COUNT(*) | +----------+ | 1 | | 1 | | 1 | | 1 | | 1 | | 1 | | 1 | | 1 | | 1 | | 1 | +----------+ 10 rows in set (0.03 sec) SELECT FOUND_ROWS(); -- the result should be 10 +--------------+ | FOUND_ROWS() | +--------------+ | 15 | +--------------+ 1 row in set (0.00 sec)
