MySQL创建函数

Question

我试图创建一个函数来插入表信息， 从数据库中自动实现的顺序id，最后我想返回它。

CREATE FUNCTION `New_Order`(
P_Customers_customer_id int(11), 
P_Employees_employee_id int(11), 
P_Shops_shop_id int(11), 
P_total double 
) RETURNS int(11) 
BEGIN 
INSERT INTO `shopsorders` 
      (`order_id`, 
      `Customers_customer_id`, 
      `Employees_employee_id`, 
      `Shops_shop_id`, 
      `total`, 
      `date`) 
     VALUES 
      (P_Customers_customer_id, 
      P_Employees_employee_id, 
      P_Shops_shop_id, 
      P_total, 
      sysdate()); 
RETURN LAST_INSERT_ID(); 
END 

Answer 1

尝试使用DELIMTER选项&修改SQL数据：

DELIMITER // 
CREATE FUNCTION `New_Order`(
P_Customers_customer_id int(11), 
P_Employees_employee_id int(11), 
P_Shops_shop_id int(11), 
P_total double 
) RETURNS int(11) 
modifies sql data 
BEGIN 
INSERT INTO `shopsorders` 
      (`order_id`, 
      `Customers_customer_id`, 
      `Employees_employee_id`, 
      `Shops_shop_id`, 
      `total`, 
      `date`) 
     VALUES 
      (P_Customers_customer_id, 
      P_Employees_employee_id, 
      P_Shops_shop_id, 
      P_total, 
      sysdate()); 
return LAST_INSERT_ID(); 
END // DELIMITER ;

你缺少分隔符选项。您需要定义一个自定义分隔符来包装您想要完成的工作的开始和结束。之后，您需要将分隔符设置为其默认值。

请参考此问题的完整示例。
