Right click on the edited query editor page and execute it to save the changes to the stored procedure.(when you change and try to close it prompts you to change as a query, but not as the stored procedure.

The first two lines are an example of how to declare variables in your stored procedure. DECLARE…uh, declares the variable. SET assigns the variable with a value. You can also do something like SELECT 1 INTO FROM .

The block that the first lines belong too just serve as an example. Other than the variables it is much like this article explained. Obviously, in the third line, the parameter declaration has values assigned to them.

The second block is searching for an existing version of a stored procedure with the name ‘sproc_insertvendor’. If it exists, then drop it so that you can create your new one or your new version if you are running this more than once.

Nothing really new in the third block although I would like to add a side note. To make a parameter optional, you can add a default value (e.g. @countOfPayments INT = 0) which is extremely valuable information to me at least.

The fourth block introduces you to Raiserror. I don’t personally know if this is built into SQL Server or not, but it is setting the @@error variable. @@ delineates system or global variables the best I can tell.

Finally, the fifth block is inserting a row as long as the person doesn’t already exist.

One last side note: try not to write if exists(select *… If you just wanna know if it exists, if exists(select 1… is more performant and gives you the same information you wanted to know.

Good article, author. I need to find one for advanced beginners now.

This is the best article I have ever found online. Your instruction is extremely easy and helpfulfor me to understand and use for my work.
Truly appreciate you!
Best regards,

This was a really informative article for us beginner SQL developers. The procedure was not very complex and easy to understand. I have been studying from a high level SQL developer in order to understand SQL better and he very much confused me with the very advanced code that he was using. Example of more complex code

/*
declare @today datetime
SET @Today = getdate()
EXECUTE sproc_insertvendor @name = ‘something Else’, @countofpayments = 3, @lastpaydate = @Today, @nextpaydate = @Today, @Comments = null
*/

IF EXISTS (SELECT * FROM SYSOBJECTS WHERE Name = ‘sproc_insertvendor’)
DROP PROCEDURE sproc_insertvendor
GO

CREATE PROCEDURE sproc_insertvendor
@name varchar(200),
@countOfPayments int,
@LastPayDate datetime,
@nextpaydate datetime,
@comments ntext
AS

if exists (
select *
from vendor v
where v.name = @name
)
BEGIN
Raiserror(‘%s already exists!’,16,2,@name)
END

if @@error=0
BEGIN
INSERT INTO vendor (Name,CountOfPayments,LastPayDate,NextPayDate,Comments)
VALUES (@Name,@CountOfPayments,@LastPayDate,@NextPayDate,@Comments)
SELECT @@Identity
END

RETURN

GO

I was reading your article and I would like to appreciate you for making it very simple and understandable. This article gives me a basic idea of stored procedure and it will help me a lot.

Thank you very much!

create procedure insert1(@userid int,@username varchar(50))
as
begin
insert into emp(id,name)values(@userid,@username)
end

NOTE:(id,name) are the columns of table in which you want to insert data.

CALLING STORED PROCEDURE :

initialize this globally:
public partial class1:class
{
sqlconnection con;
sqlcommand cmd;
}

on page_load(): // write on page load()
{
con=new sqlconnection(“Connection string”);
cmd=new sqlcommand();
cmd.connection=con;
cmd.commandtype=commandtype.stored procedure;
}

on button_click() // write on insert button_clik event

{
cmd.parameters.clear();
cmd.commandtext=”insert1″;
// stored procedure name just created.
cmd.parameters.addwithvalue(“@userid”,textbox1.text);

cmd.parameters.addwithvalue(“@username”,textbox2.text);
con.open();
cmd.executenonquery();
messagebox.show(“stored procedure inserted…”);
con.close();
}
