mysql：游标嵌套使用

解决方案：

从A表取一个字段的值和从B表取一个字段的值一一组合作为插入数据源。

drop procedure  if exists test_team_user;
create PROCEDURE test_team_user()


BEGIN
DECLARE done INT DEFAULT 0;
DECLARE userid VARCHAR(32);
DECLARE teamid VARCHAR(32);
DECLARE id int DEFAULT 100;
/*声明一个游标*/
DECLARE  c_userid  cursor for select user_id from sys_user where account like 'dor%'or account like 'nur%';
/* 异常处理 */
declare CONTINUE HANDLER FOR SQLSTATE '02000' SET done=1;
/*打开游标*/
open c_userid;


while done<>1 do
FETCH c_userid into userid;
begin
DECLARE inner_done INT DEFAULT 0;
/*声明一个游标*/
DECLARE  c_teamid  cursor for select team_id from sys_team;
/* 异常处理 */
declare CONTINUE HANDLER FOR SQLSTATE '02000' SET inner_done=1;
open c_teamid;
/*循环插入数据*/
while inner_done<>1 do
FETCH c_teamid into teamid;
INSERT INTO `sys_team_user` (`ID`, `TEAM_ID`, `USER_TYPE`, `USER_ID`, `JOIN_TIME`, `JOIN_STATUS`) VALUES (id, teamid, '1', userid, '2016-10-26 17:45:45', '1');
set id=id+1;
end while;
/*关闭游标*/
CLOSE c_teamid;
end;
end while;
/*关闭游标*/
CLOSE c_userid;
END;
