-2

谁能告诉我，为什么这不起作用如何使用select查询创建临时表并将其插入到mysql中？

Create Procedure LeaveUpdate() 
Begin 
CREATE TEMPORARY TABLE leavebal AS (SELECT * FROM tbl_leave_balance WHERE month = month(DATE_SUB(now(), INTERVAL 1 MONTH)) and year = year(DATE_SUB(now(), INTERVAL 1 MONTH))); 
UPDATE leavebal SET leave_balance = 0 WHERE leave_balance < 0; 
UPDATE leavebal SET month = month(now()), year = year(now()), leaves_taken = 0, carry_forward = leave_balance, comp_off = 0; 
UPDATE leavebal SET total_leaves = carry_forward + leaves_allowed + comp_off, leave_balance = carry_forward + leaves_allowed + comp_off; 
INSERT INTO tbl_leave_balance (emp_id, month, year, carry_forward, leaves_allowed, comp_off, total_leaves, leaves_taken, leave_balance) 
SELECT emp_id, month, year, carry_forward, leaves_allowed, comp_off, total_leaves, leaves_taken, leave_balance FROM leavebal; 
End

必须使用delimiter，试试这个：

DELIMITER $$ 

    DROP PROCEDURE IF EXISTS `LeaveUpdate` $$ 
Create Procedure LeaveUpdate() 
Begin 
CREATE TEMPORARY TABLE leavebal AS (SELECT * FROM tbl_leave_balance WHERE month = month(DATE_SUB(now(), INTERVAL 1 MONTH)) and year = year(DATE_SUB(now(), INTERVAL 1 MONTH))); 
UPDATE leavebal SET leave_balance = 0 WHERE leave_balance < 0; 
UPDATE leavebal SET month = month(now()), year = year(now()), leaves_taken = 0, carry_forward = leave_balance, comp_off = 0; 
UPDATE leavebal SET total_leaves = carry_forward + leaves_allowed + comp_off, leave_balance = carry_forward + leaves_allowed + comp_off; 
INSERT INTO tbl_leave_balance (emp_id, month, year, carry_forward, leaves_allowed, comp_off, total_leaves, leaves_taken, leave_balance) 
SELECT emp_id, month, year, carry_forward, leaves_allowed, comp_off, total_leaves, leaves_taken, leave_balance FROM leavebal; 
End$$ 

    DELIMITER ;
