无法创建过程phpMyAdmin MYSQL错误

Question

救命！！ 我被卡住了，我不知道怎么了。
我正在使用MySql，但是它不会创建过程，我没有主意。

CREATE PROCEDURE sc_new_ord(IN inscid INT, IN incust_id INT, IN indeltype_id INT, IN duty_it INT, IN delcost INT, OUT ttmount INT, OUT outordid INT)
BEGIN
  DECLARE ord_id INT;
  DECLARE total INT;

  INSERT INTO tbl_orders (customer_id, ship_type_id, rate_id, status) VALUES
         (incust_id, indeltype_id, duty_it,0);

  SELECT LAST_INSERT_ID() INTO inscid;

  INSERT INTO tbl_ord_det (ord_id,inv_id, item, qtty, price)
  SELECT ord_id, tbl_inventory.Inv_id, tbl_inventory.Item, tbl_shp_ct.qtty,
              COALESCE(NULLIF(tbl_inventory.Offer_Price, 0), tbl_inventory.Price) AS price
  FROM        tbl_shp_ct
  INNER JOIN  tbl_inventory
                ON tbl_shp_ct.inv_id = tbl_inventory.Inv_id
  WHERE tbl_shp_ct.sc_id = inscid AND tbl_shp_ct.buy_now;
    -- total amount
  UPDATE tbl_orders
  SET    tt_mnt = (SELECT SUM(price * qtty)FROM tbl_ord_det WHERE ord_id = ord_id)
  WHERE  ord_id = ord_id;
  CALL sc_empty (inscid);
  SELECT (SUM(price * qtty) FROM tbl_ord_det WHERE  ord_id = ord_id) as tt INTO total;
  SELECT total, delcost, (total+delcost) INTO ttmount;
  SELECT ord_id INTO outordid;
END

完全错误：MySQL说：文档

1064-您的SQL语法有误； 检查与您的MariaDB服务器版本相对应的手册以获取在第3行的''附近使用的正确语法

如果您使用的是mysql数据库，请尝试按以下方法操作，如果仍然遇到错误，则共享错误-

DELIMITER $$
CREATE PROCEDURE sc_new_ord(IN inscid INT, IN incust_id INT, IN indeltype_id INT, IN duty_it INT, IN delcost INT, OUT ttmount INT, OUT outordid INT)
BEGIN
  DECLARE ord_id INT;
  DECLARE total INT;

  INSERT INTO tbl_orders (customer_id, ship_type_id, rate_id, status) VALUES
         (incust_id, indeltype_id, duty_it,0);

  SELECT LAST_INSERT_ID() INTO inscid;

  INSERT INTO tbl_ord_det (ord_id,inv_id, item, qtty, price)
  SELECT ord_id, tbl_inventory.Inv_id, tbl_inventory.Item, tbl_shp_ct.qtty,
              COALESCE(NULLIF(tbl_inventory.Offer_Price, 0), tbl_inventory.Price) AS price
  FROM        tbl_shp_ct
  INNER JOIN  tbl_inventory
                ON tbl_shp_ct.inv_id = tbl_inventory.Inv_id
  WHERE tbl_shp_ct.sc_id = inscid AND tbl_shp_ct.buy_now;
    -- total amount
  UPDATE tbl_orders
  SET    tt_mnt = (SELECT SUM(price * qtty)FROM tbl_ord_det WHERE ord_id = ord_id)
  WHERE  ord_id = ord_id;
  CALL sc_empty (inscid);
  SELECT (SUM(price * qtty) FROM tbl_ord_det WHERE  ord_id = ord_id) as tt INTO total;
  SELECT total, delcost, (total+delcost) INTO ttmount;
  SELECT ord_id INTO outordid;
END$$
DELIMITER ;

Answer 2

更改

SELECT (SUM(price * qtty) FROM tbl_ord_det WHERE  ord_id = ord_id) as tt INTO total;

至

SELECT SUM(price * qtty) as tt FROM tbl_ord_det WHERE  ord_id = ord_id INTO total;

通过将as tt移动到正确的位置。
