2 SQL queries in one stored procedure - sql

Question

Can I run 2 queries in one stored procedure ?
CREATE PROCEDURE AddProd
#Store_Name varchar(50),
#Price int,
#Prod_Name varchar(50),
#Qty int,
#ProductDescription varchar(50),
#RatingSum int,
#RatingCount int,
#ProductImage varchar(50),
#Prod_Date date,
AS
BEGIN
SELECT S.Store_ID
FROM Store S
WHERE StoreName=#StoreName
INSERT INTO Product (Store_ID, Price, Prod_Name, Qty, ProductDescription, RatingSum, RatingCount, ProductImage, Prod_Date)
VALUES (S.Store_ID, #Price, #Prod_Name, #Qty, #ProductDescrpition, #RatingSum, #RatingCount, #ProductImage, #Prod_Date)
END
GO
For this code above, I want retrieve a STORE_ID by giving the STORE_NAME the user give as a parameter.
I want to use this STORE_ID in the INSERT statement.
Can I do this ?!
AKA, is the S.store_ID returned from the first query, the same as that one I used in "Values" ?

Answer 1

Technically, you can do this in a single query:
INSERT INTO Product
(Store_ID, Price, Prod_Name, Qty, ProductDescription, RatingSum, RatingCount, ProductImage, Prod_Date)
SELECT S.Store_ID, #Price,#Prod_Name,#Qty,#ProductDescription,#RatingSum,#RatingCount,#ProductImage,#Prod_Date
FROM Store S
WHERE StoreName=#StoreName
I don't have test data handy to check, but you may have to give the appropriate names to each of the columns in the select clause from that query, instead of just the variable names. The only other reason this might not work is if you also wanted to return the selected storeID from the stored procedure, but even in that case you can just add an OUTPUT clause:
INSERT INTO Product
(Store_ID, Price, Prod_Name, Qty, ProductDescription, RatingSum, RatingCount, ProductImage, Prod_Date)
OUTPUT S.Store_ID
SELECT S.Store_ID, #Price,#Prod_Name,#Qty,#ProductDescription,#RatingSum,#RatingCount,#ProductImage,#Prod_Date
FROM Store S
WHERE StoreName=#StoreName
But for the title question, the answer is affirmative; you can execute multiple statements inside a single stored procedure.

Answer 2

unless you want to return the storeID from the sp remove that query and put it into the insert
INSERT INTO Product (Store_ID,Price,Prod_Name,Qty,ProductDescription,RatingSum,RatingCount,ProductImage,Prod_Date)
values (
(SELECT S.Store_ID FROM Store S WHERE StoreName=#StoreName),
#Price,#Prod_Name,#Qty,#ProductDescrpition,#RatingSum,#RatingCount,#ProductImage,#Prod_Date)

If StoreID is unique for each store name you can store it in a variable and use it in your insertion
CREATE PROCEDURE AddProd
#Store_Name varchar(50),
#Price int,
#Prod_Name varchar(50),
#Qty int,
#ProductDescription varchar(50),
#RatingSum int,
#RatingCount int,
#ProductImage varchar(50),
#Prod_Date date,
AS
BEGIN
DECLARE #StoreID [DataType]
SELECT #StoreID = S.Store_ID
FROM Store S
WHERE StoreName=#StoreName
INSERT INTO Product (Store_ID,Price,Prod_Name,Qty,ProductDescription,RatingSum,RatingCount,ProductImage,Prod_Date)
values (#StoreID,#Price,#Prod_Name,#Qty,#ProductDescrpition,#RatingSum,#RatingCount,#ProductImage,#Prod_Date)
END
GO
In any scenario you can use the following
CREATE PROCEDURE AddProd
#Store_Name varchar(50),
#Price int,
#Prod_Name varchar(50),
#Qty int,
#ProductDescription varchar(50),
#RatingSum int,
#RatingCount int,
#ProductImage varchar(50),
#Prod_Date date,
AS
BEGIN
INSERT INTO Product (Store_ID,
Price,
Prod_Name,
Qty,
ProductDescription,
RatingSum,
RatingCount,
ProductImage,
Prod_Date
)
SELECT
S.Store_ID
#StoreID,
#Price,
#Prod_Name,
#Qty,
#ProductDescrpition,
#RatingSum,
#RatingCount,
#ProductImage,
#Prod_Date
FROM Store S
WHERE StoreName=#StoreName
END
GO
