在mySQL中创建过程

我在phpmyadmin中创建了一个mySQL过程，它一直抛出这个错误：＃1064 - 你的SQL语法错误;检查对应于您的MySQL服务器版本的手册，以便在第18行使用正确的语法在mySQL中创建过程

我试过下面的代码，没有使用分隔符，没有用。任何人都可以指出这段代码有什么问题吗？谢谢！

DELIMITER \\ 
CREATE PROCEDURE ORDERBOOKS(IN store VARCHAR(10), IN title VARCHAR(50)) 
BEGIN 
    DECLARE order_num VARCHAR(100); 
    DECLARE tod DATE; 
    SELECT @ordered_qty := qty FROM customer_sales WHERE customer_sales.store_id = store AND customer_sales.title_id = title; 
    SELECT @in_stock := qty FROM store_inventories WHERE store_inventories.stor_id=store AND store_inventories.title_id = title; 
    SELECT @threshold := minStock FROM store_inventories WHERE store_inventories.stor_id=store AND store_inventories.title_id = title; 
    SET order_num = CONCAT(store, title); 
    SET tod = GETDATE(); 
    IF (@ordered_qty < (@in_stock - @threshold)) THEN UPDATE store_inventories SET qty = (@in_stock - @ordered_qty) WHERE store_inventories.stor_id = store and store_inventories.title_id = title; 
    ELSE 
     INSERT INTO pending_orders(stor_id, ord_num, title_id, qty, date, fulfilled) VALUES(store, order_num, title, (@ordered_qty + @threshold), tod ,1); 
     INSERT INTO sales VALUES(store, order_num, tod); 
     INSERT INTO salesdetail VALUES(store, order_num, title , (@ordered_qty + @threshold),0); 
     UPDATE pending_orders SET fulfilled=0 WHERE pending_orders.stor_id = store AND pending_orders.title_id = title; 
     UPDATE store_inventories SET qty = (@threshold + @in_stock) WHERE store_inventories.stor_id = store and store_inventories.title_id= title; 
     DELETE FROM pending_orders WHERE pending_orders.stor_id = store AND pending_orders.title_id = title; 
END\\ 

DELIMITER ;

缺少结束如果 – e4c5

相依尖端：分配用户定义'@'变量是安全的（且无声）如果使用标量子查询：'SET @ordered_qty = （SELECT qty FROM customer_sales WHERE customer_sales.store_id = store AND customer_sales.title_id = title）;'如果你决定重构这个，你可能会倾向于将原来的语句重写为'SELECT ... INTO'，（经常）[意外后果]（http://dba.stackexchange.com/a/35207/11651）旧值从调用到同一连接的调用。现在更好地使用更安全的任务范例，fwiw。 –

尝试这一个：

CREATE PROCEDURE ORDERBOOKS(IN store VARCHAR(10), IN title VARCHAR(50)) 
BEGIN 
    DECLARE order_num VARCHAR(100); 
    DECLARE tod DATE; 
    SELECT @ordered_qty := qty FROM customer_sales WHERE customer_sales.store_id = store AND customer_sales.title_id = title; 
    SELECT @in_stock := qty FROM store_inventories WHERE store_inventories.stor_id=store AND store_inventories.title_id = title; 
    SELECT @threshold := minStock FROM store_inventories WHERE store_inventories.stor_id=store AND store_inventories.title_id = title; 
    SET order_num = CONCAT(store, title); 
    SET tod = GETDATE(); 
    IF (@ordered_qty < (@in_stock - @threshold)) THEN UPDATE store_inventories SET qty = (@in_stock - @ordered_qty) WHERE store_inventories.stor_id = store and store_inventories.title_id = title; 
    ELSE 
     INSERT INTO pending_orders(stor_id, ord_num, title_id, qty, date, fulfilled) VALUES(store, order_num, title, (@ordered_qty + @threshold), tod ,1); 
     INSERT INTO sales VALUES(store, order_num, tod); 
     INSERT INTO salesdetail VALUES(store, order_num, title , (@ordered_qty + @threshold),0); 
     UPDATE pending_orders SET fulfilled=0 WHERE pending_orders.stor_id = store AND pending_orders.title_id = title; 
     UPDATE store_inventories SET qty = (@threshold + @in_stock) WHERE store_inventories.stor_id = store and store_inventories.title_id= title; 
     DELETE FROM pending_orders WHERE pending_orders.stor_id = store AND pending_orders.title_id = title; 
    END IF 
END

';'在'END IF'之后是必需的，为了清晰起见，您应该将语句分隔符和分隔符声明留在中。 –
