Ok, I hadn't notices the improvements in SSMS.

Running my very short code there raised an error that is easy to locate:
Msg 102, Niveau 15, État 1, Procédure T_U_Catalogue, Ligne 60
Syntaxe incorrecte vers '@error_number'.

So the trigger is the cause. Here is the code (generated by xCase):

USE [Softex];
GO
SET ANSI_NULLS ON;
GO
SET QUOTED_IDENTIFIER ON;
GO

           @error_message   VARCHAR(255)

    SELECT @row_count = @@rowcount
    IF @row_count = 0
       RETURN

IF UPDATE([FK_iOldCodeId])
   BEGIN
        SELECT @null_row_count =

           IF (
               SELECT COUNT(*)

                          @error_message='Cannot update child in "[dbo].[Catalogue]".'
                   GOTO error
              END
   END

               )
        BEGIN

RETURN

We are approaching.
