CREATE TABLE t1 (a INT);
|
INSERT INTO t1 VALUES (1),(2);
|
|
--connect (con1,localhost,root,,)
|
CREATE TABLE t2 AS SELECT a, GROUP_CONCAT(LENGTH(a), 1/ROW_COUNT()) AS f FROM t1 GROUP BY a WITH ROLLUP;
|
|
# Cleanup
|
--disconnect con1
|
--connection default
|
DROP TABLE t1, t2;
|
Same effect can be achieved within a single connection, if there is no INSERT, or ROW_COUNT value is otherwise reset to 0.
