SP not saving records as expected

Question

Hi folks, I’m not sure why my SP is not saving the data as expected, instead of saving the data within the designated record set i.e. where LinkID = @LinkID, it creates a new record....
What have I done wrong...
GO
ALTER PROCEDURE [dbo].[AddTermsCondition]
/******tblLink_OrderProduct******/
@Terms bit,
@TermsEmail bit,
@LinkID int
AS
SET NOCOUNT ON
SELECT LinkID
FROM Link_OrderProduct
WHERE LinkID = @LinkID
BEGIN
Begin TRANSACTION
INSERT INTO [TyreSanner].[dbo].[Link_OrderProduct](Terms, TermsEmail)
VALUES (@Terms,@TermsEmail)
COMMIT TRANSACTION
END

Answer 1

Hi,
I HIGHLY recommend to learn basic SQL!
We can help in any nees probably, but do you really want to waste your time, to write a new question each time, while you can learn the basics in 1 week, and then even help others? for more complex need or for question during learning it will be our pleasure
to help you. I might be wrong, but I am guessing that you did not tried to learn the basic till now, in ordered manner :-(
* your query insert new row to the table since you wrote a simple insert query, instead of UPDATE query. check Jingyang's
solution.
This is short tutorial to learn SQL (SQL is the basic language for all common databases which works with tables). In one week you can learn the language and become "expert" :-)
Next you can learn the extantion language for SQL Server which named transact-sql :-)

** I might be mistaking and the explanation is not clear :-)
if you want to do more then "just" update, then pls clarify. You might want to do INSERT if the LinkID is not exist and UPDATE if it is exist. In this case you can use MERGE statement as explained here: http://msdn.microsoft.com/en-us/library/bb510625.aspx
