Overview
As mentioned in the tutorial overview a stored procedure is nothing more than stored SQL code that you would like to use over and over again. In this example we will look at creating a simple stored procedure.
Explanation
Before you create a stored procedure you need to know what your end result is, whether you are selecting data, inserting data, etc..
In this simple example we will just select all data from the Person.Address table that is stored in the AdventureWorks database.
So the simple T-SQL code excuting in the AdventureWorks database would be as follows which will return all rows from this table.
SELECT * FROM Person.Address
To create a stored procedure to do this the code would look like this:
USE AdventureWorks GO CREATE PROCEDURE dbo.uspGetAddress AS SELECT * FROM Person.Address GO
To call the procedure to return the contents from the table specified, the code would be:
EXEC dbo.uspGetAddress -- or EXEC uspGetAddress --or just simply uspGetAddress
When creating a stored procedure you can either use CREATE PROCEDURE or CREATE PROC. After the stored procedure name you need to use the keyword "AS" and then the rest is just the regular SQL code that you would normally execute.
One thing to note is that you cannot use the keyword "GO" in the stored procedure. Once the SQL Server compiler sees "GO" it assumes it is the end of the batch.
Also, you can not change database context within the stored procedure such as using "USE dbName" the reason for this is because this would be a separate batch and a stored procedure is a collection of only one batch of statements.
