SQL

create procedure spInsertArts(
@artsId int out,
@name varchar(50),
@category varchar(50),
@artistId int
)
as
     begin
	select @artistId=SCOPE_IDENTITY()
		if exists(select artistId from artist)
         insert into arts(name,category,artistId) values(@name,@category,@artistId)
      end

when i execute it,it is giving error as:Procedure or function 'spInsertArts' expects parameter '@artistId', which was not supplied.i want to set artistId to latest value of artistId in artist Table.pls help.

If artsID is an identity column (guaranteeing uniqueness and monotonicity), you could ask for

SQL

SELECT @artsID = max(artID) from arts

(assuming that's the column name) It may be sensible for you to use this in a subquery, depending upon how you arrange things.

Now, after an insert, and before you close the connection, you can use

SELECT TOP 1 @@IDENTITY From arts

and it would be returned from your stored procedure.

Do not forget to include

SET NOCOUNT ON

in your procedure or the return record set will be a mess

change like this

create procedure spInsertArts(
@artsId int out=null,
@name varchar(50)=null,
@category varchar(50)=null,
@artistId int<pre>=null
)
as
     begin
	select @artistId=SCOPE_IDENTITY()
		if exists(select artistId from artist)
         insert into arts(name,category,artistId) values(@name,@category,@artistId)
      end
