    The END IF is incorrect.

    Do it like this:

     DECLARE @error int

  If (SELECT ID_Projet FROM tblProjet WHERE No_Projet=@no_Projet)> 0
     SET @error=1

    or this:

     DECLARE @error int

  If (SELECT ID_Projet FROM tblProjet WHERE No_Projet=@no_Projet)> 0
  Begin
     SET @error=1
  End

    Check HERE for documentation.

    If you’re trying to see the number of rows with that restriction you should do it like this:

     DECLARE @error int

  If (SELECT count(ID_Projet) FROM tblProjet WHERE No_Projet=@no_Projet)> 0
  Begin
     SET @error=1
  End
