OUT输出参数:该值可在存储过程内部被改变,并可返回 INOUT输入输出参数:调用时指定,并且可被改变和返回 . IN参数例子 : 1. mysql > DELIMITER // 2. mysql > CREATE PROCEDURE demo_in_parameter(IN p_in int) 3. -> BEGIN 4. -> SELECT p_in; 5. -> SET p_in=2; 6. -> SELECT p_in; 7....
3 3、创建存储过程：create procedure procedure_name([procedure_parameter …..])routine_bodyprocedure_parameter：表示存储过程的参数，3种参数类型：in输入参数：只能传入，out输出参数，inout:输入输出参数 4 4、举个例子：首先右击stored PROCEDURE,选择第一个选项，双击进去，如图所示：5 5、然后把创建存储过程...
mysql > DELIMITER // mysql > CREATE PROCEDURE demo_out_parameter(OUT p_out int) -> BEGIN -> SELECT p_out; -> SET p_out=2; -> SELECT p_out; -> END; -> // mysql > DELIMITER ; 执行结果: mysql > SET @p_out=1; mysql > CALL sp_demo_out_parameter(@p_out); +---+ | p...
CALL proc_name ([parameter[,...]]) 1. 示例: call sp_simon_test("夏") 1. 二、存储过程的参数 MySQL存储过程的参数用在存储过程的定义,共有三种参数类型,IN,OUT,INOUT create procedure 过程名字(IN | OUT | INOUT 参数名 参数类型) 1. ...
OUT 输出参数:该值可在存储过程内部被改变,并可返回 INOUT 输入输出参数:调用时指定,并且可被改变和返回 Ⅰ. IN参数例子 创建: mysql > DELIMITER // mysql > CREATE PROCEDURE demo_in_parameter(IN p_in int) -> BEGIN -> SELECT p_in; -> SET p_in=2; ...
