END

I try to use when then for update my ID and Name

If Id is greater than 1 i want to update otherwise no update.

Answer 1

I think this is what you are after:

ALTER PROCEDURE [dbo].[SP_MY_STORE_PROCEDURED]
(
@ID INT,
@NAME VARCHAR(50)
)
AS
BEGIN
    UPDATE MY_TABLE
    SET NAME = @NAME
    WHERE ID = @ID
END

You do not need to check ID>1 since you are checking the equality with @ID. If you want to be sure that this doesn't happen if @ID <=1 then you may try the following:

ALTER PROCEDURE [dbo].[SP_MY_STORE_PROCEDURED]
(
@ID INT,
@NAME VARCHAR(50)
)
AS
BEGIN
    IF @ID > 1
        UPDATE MY_TABLE
        SET NAME = @NAME
        WHERE ID = @ID
END

I'm not sure exactly what you're trying to update. Are you trying to change the name on a user record with id = @ID?

ALTER PROCEDURE [dbo].[SP_MY_STORE_PROCEDURED]
(
@ID INT,
@NAME VARCHAR(50)
)
AS
BEGIN

    UPDATE MY_TABLE
    SET Name = @Name
    WHERE Id = @ID and @ID > 1

END

This should do it.

ALTER PROCEDURE [dbo].[SP_MY_STORED_PROCEDURE] ( @ID INT, @NAME VARCHAR(50) )
AS
BEGIN
    IF @ID > 1
        UPDATE MY_TABLE
        SET Name = @Name
        WHERE Id = @ID
END
