MYSQL通过SQL脚本创建存储过程(游标删除多表数据)

首先描述一下业务处理存储过程功能：删除除系统管理员创建的角色和对应的业务表数据。

--  CALL P_INTSYS('%_10006%','10006');
drop procedure if exists wmscloud_test.P_INTSYS;

CREATE PROCEDURE wmscloud_test.P_INTSYS(IN likeTableName VARCHAR(30),IN esCorCode VARCHAR(30))

BEGIN
 
  -- 需要定义接收游标数据的变量 
  DECLARE table_ VARCHAR(50);
  -- 遍历数据结束标志
  DECLARE done INT DEFAULT FALSE;
  -- 游标
  DECLARE cur CURSOR FOR SELECT TABLE_NAME FROM (SELECT TABLE_NAME from information_schema.tables WHERE TABLE_NAME LIKE likeTableName ) allTables;
  -- 将结束标志绑定到游标
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;
  -- 打开游标
  OPEN cur;
   -- 开始循环
  read_loop: LOOP

  -- 提取游标里的数据，这里只有一个，多个的话也一样；
  FETCH cur INTO table_;
  -- 声明结束的时候
  IF done THEN
    LEAVE read_loop;
  END IF;

  -- 这里做你想做的循环的事件
    SET @delete_table=CONCAT(' DELETE FROM ',table_,';');
    PREPARE delete_table FROM @delete_table;
    EXECUTE delete_table;
  

  END LOOP;
  -- 关闭游标
  CLOSE cur;

  -- 删除,除去系统管理员创建的外其余用户和角色
  SET @delete_table=CONCAT(' DELETE FROM es_user WHERE CREATOR!=1 and ES_COR_CODE=',esCorCode);
  PREPARE delete_table FROM @delete_table;
  EXECUTE delete_table;

  SET @delete_table=CONCAT(' DELETE FROM es_role WHERE CREATOR!=1 and ES_COR_CODE=',esCorCode);
  PREPARE delete_table FROM @delete_table;
  EXECUTE delete_table;

END

执行脚本生成的函数
