下面的这个过程返回
错误代码:1222:使用的 SELECT 语句的列数不同
CREATE PROCEDURE `dev_getDashBoard`(cognito VARCHAR(100))
BEGIN
DECLARE id_user,team_last INT;
SELECT ct.hasInvoice,ct.currentCredits,ct.hasPremium,u.lastTeam INTO team_last FROM configTeam ct
INNER JOIN users u ON u.lastTeam = ct.team_id
WHERE u.identityId = cognito COLLATE utf8_unicode_ci LIMIT 1
CALL otherProcedure(team_last);
END
sql 总是返回一行。为什么mysql返回错误?
