5つの乱数を生成するMySQLストアドプロシージャを作成しますか？

次のクエリを使用して、5つの乱数を生成するストアドプロシージャを作成できます-

mysql> DELIMITER //
mysql> DROP PROCEDURE IF EXISTS RandomNumbers;
    -> CREATE PROCEDURE RandomNumbers()
    -> BEGIN
    -> SET @i = 0;
    -> REPEAT
    -> SELECT RAND() AS 'Random Number';
    -> SET @i = @i + 1;
    -> UNTIL @i >=5 END REPEAT;
    -> END
    -> //
Query OK, 0 rows affected (0.16 sec)

Query OK, 0 rows affected (0.16 sec)

次に、プロシージャを呼び出して結果を取得します-

mysql> DELIMITER ;
mysql> CALL RandomNumbers();
