Stored Procedure in SQL

This article I will give you some basic syntax about stored procedure in SQL.

Stored Procedure:

Stored Procedure is the prepared SQL codes that we can save, so the code can be reused over and over again.

It is suitable for some SQL queries we need to use frequently.

There are three kinds of stored procedure:

1. No parameter
2. One parameter
3. multiple parameters

•Stored Procedure (No parameter) Syntax

CREATE PROCEDURE procedure_name
AS
sql_statement
GO
EXEC procedure_name

•Stored Procedure (One parameter) Syntax

CREATE PROCEDURE [dbo].[oneparameter]
@ProductCatergoryID int
AS
SELECT *FROM Production.ProductCategoryID
GO
EXEC oneparameter @ProductCatergoryID = '4'

•Stored Procedure (multiparameter) Syntax

CREATE PROCEDURE [dbo].[multiparameter]
@ProductCategoryID int, @Name varchar(50)
AS
SELECT *FROM Production.ProductCategory pc
WHERE pc.ProductCategoryID = @ProductCategoryID and pc.Name = @Name
GO
EXEC multiparameter @ProductCategoryID = '4', @Name = 'Accessories'

I will record all knowledge I touch in my Data journey.
