我的SQL存储过程带有更新

I have a stored procedure that is used when a new transaction is inserted. This procedure inserts properly into the transactions table, but I also need to update another related table based on inserted values.

我有一个插入新事务时使用的存储过程。此过程正确插入到事务表中,但我还需要根据插入的值更新另一个相关表。

Based on the Product_ID I need to update PT_Pct_to_Salon in a table called 'Salon' with a value from a table called 'Zen_Products_Description'. The related salon can be found using the 'Salon_ID' from insert which is equivalent to the 'Salon' table's PK ID.

基于Product_ID,我需要在名为“Salon”的表中使用名为“Zen_Products_Description”的表中的值更新PT_Pct_to_Salon。可以使用插入中的'Salon_ID'找到相关的沙龙,它相当于'沙龙'表的PK ID。

The value I need to insert is in the 'web_share' field of the 'Zen_Products_Description' table. The related row in 'Zen_Products_Description' can be matched by matching the inserted value 'Product_ID' with the PK of 'Zen_Products_Description' which is called 'products_id'.

我需要插入的值位于'Zen_Products_Description'表的'web_share'字段中。 'Zen_Products_Description'中的相关行可以通过将插入的值'Product_ID'与'Zen_Products_Description'的PK匹配来匹配,该PK称为'products_id'。

I am using MySQL 5.

我正在使用MySQL 5。

BEGIN
INSERT INTO Transactions
(Cart_Trans_ID, Customer_ID, Pass_Through_Amt, Product_ID, Product_Name, Product_Qty, Salon_ID,  Stylist_ID, Trans_Type, customerAddress, customerCity, customerEmail, customerFirstName, customerLastName, customerPhone, customerPostal, customerState) 
VALUES (Cart_Trans_ID, Customer_ID, Pass_Through_Amt, Product_ID, Product_Name, Product_Qty, Salon_ID, Stylist_ID, Trans_Type, customerAddress, customerCity, customerEmail, customerFirstName, customerLastName, customerPhone, customerPostal, customerState);
Insert Into Zen_Products_Description
(products_id, products_name) 
Values (Product_ID, Product_Name) ON DUPLICATE KEY UPDATE
products_name = Product_Name;

//this is where I try unsuccessfully to update
update Salon
set PT_Pct_to_Salon = Zen_Products_Description.web_share
join Salon
on Salon.Salon_ID = Transactions.Salon_ID
join Zen_Products_Description
on Zen_Products_Description.products_id = Transactions.Product_ID;

END

lol - you forgot to ask a question... be succinct and i'll help you

大声笑 - 你忘了问一个问题......简洁,我会帮助你

BEGIN 
  INSERT INTO Transactions 
    (Cart_Trans_ID, Customer_ID, 
     Pass_Through_Amt, Product_ID, Product_Name, 
     Product_Qty, Salon_ID, Stylist_ID, 
     Trans_Type, customerAddress, customerCity, 
     customerEmail, customerFirstName, customerLastName, 
     customerPhone, customerPostal, customerState) 
  VALUES 
    (Cart_Trans_ID, Customer_ID, 
     Pass_Through_Amt, Product_ID, Product_Name, 
     Product_Qty, Salon_ID, Stylist_ID, 
     Trans_Type, customerAddress, customerCity, 
     customerEmail, customerFirstName, customerLastName, 
     customerPhone, customerPostal, customerState); 


Insert Into Zen_Products_Description 
  (products_id, products_name) 
Values 
  (Product_ID, Product_Name) 

ON DUPLICATE KEY 

UPDATE products_name = Product_Name

########## everything above here is immaterial

update Salon 
  set PT_Pct_to_Salon = Zen_Products_Description.web_share 
join Salon on Salon.Salon_ID = Transactions.Salon_ID 
join Zen_Products_Description 
  on Zen_Products_Description.products_id = Transactions.Product_ID;

############### here is update

UPDATE salon A 
INNER JOIN Transactions B ON A.salon_ID = B.salon_ID
INNER JOIN Zen_Products_Description C on C.Products_id = B.product_id
SET A.PT_Pct_to_Salon = C.web_share

## , a.x = b.x etc... ## and by the way - learn how to format your code so people can read it...
