  Some additional knowledge/information/logic is needed to complete this as djj mentioned, here is some quick code to get you started.

  😎

  USE tempdb;

  GO

  SET NOCOUNT ON;

  IF OBJECT_ID('dbo.Webs') IS NULL

  BEGIN

  Create Table dbo.Webs

  (

  FullURL nvarchar(255)

  );

  Insert Into dbo.Webs

  Select 'PWA/ENV0103' UNION ALL Select 'PWA/FBP.004' UNION ALL Select 'PWA/IP.CE361886' UNION ALL Select 'PWA/OFS.CE366077' UNION ALL

  Select 'PWA/NWK0108' UNION ALL Select 'PWA/TK.2347' UNION ALL Select 'PWA/DRHTest2' UNION ALL Select 'PWA/IDTS.CE363798' UNION ALL
