创建一个生成五个随机数的MySQL存储过程？
借助以下查询，我们可以创建一个存储过程来生成五个随机数-
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
-> //现在，调用该过程以获取结果-
mysql> DELIMITER ; mysql> CALL RandomNumbers(); +---------------------+ | Random Number | +---------------------+ | 0.25968261739209536 | +---------------------+ 1 row in set (0.00 sec) +--------------------+ | Random Number | +--------------------+ | 0.1659662734400167 | +--------------------+ 1 row in set (0.01 sec) +---------------------+ | Random Number | +---------------------+ | 0.05078354575744229 | +---------------------+ 1 row in set (0.01 sec) +--------------------+ | Random Number | +--------------------+ | 0.7560189392008064 | +--------------------+ 1 row in set (0.04 sec) +------------------+ | Random Number | +------------------+ | 0.62774408946535 | +------------------+ 1 row in set (0.04 sec)
