MySql創(chuàng)建存儲(chǔ)過(guò)程

1.存儲(chǔ)過(guò)程描述

   用于修改主鍵生成表中的遞增值

2.存儲(chǔ)過(guò)程實(shí)現(xiàn)

SELECT @@global.sql_mode;

SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY','')); ##當(dāng)前session變量生效

DELIMITER //

-- proc_modify_primary_key_value:存儲(chǔ)過(guò)程名稱

DROP PROCEDURE IF EXISTS `proc_modify_primary_key_value`;

-- table_name:表名 set_column_name:需求設(shè)置的列 set_column_name_value：需求設(shè)置的列對(duì)應(yīng)的值 condition_column_name：條件列 condition_column_name_value：條件列值

CREATE PROCEDURE `proc_modify_primary_key_value` (IN table_name VARCHAR(20),IN set_column_name VARCHAR(30),IN set_column_name_value VARCHAR(30),IN condition_column_name VARCHAR(30),IN condition_column_name_value VARCHAR(30))

COMMENT '用于修改主鍵生成表中的遞增值'

BEGIN

set @sql_update = CONCAT("UPDATE ",table_name," SET ",set_column_name," = ",set_column_name_value," WHERE ",condition_column_name," = ",condition_column_name_value);

PREPARE sql_update from @sql_update;

EXECUTE sql_update;

DEALLOCATE PREPARE sql_update;

END;

//

DELIMITER ;

3.調(diào)用存儲(chǔ)過(guò)程

SELECT @@global.sql_mode;

SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY','')); ##當(dāng)前session變量生效

CALL proc_modify_primary_key_value('primary_key_generator_table','value','1','name','PK_CUSTOMER_ID')
