Handle multiple input values in one SP Parameter

Hi ,

I'm using that SP

ALTER Procedure [dbo].[SP_GSK_Value]
(

@PSKUCode Varchar(50)=null)

RIGHT NOW , @PSKUCode can accept one value based on this ..

exec [SP_GSK_Value] 'AB001'

FROM [GSKCH].[dbo].[SKUWISE] A(NOLOCK)
   WHERE [PSKUCode]=ISNULL(@PSKUCode,PSKUCode)

But, I want that It can accept multiple dynamic values from Table directly

For example

exec [SP_GSK_Value] 'AB001,BC002,NF003'
