I'm having a noob problem passing a data table type to a stored procedure.

Here is the implementation :

DECLARE @T TVARIABLE



    INSERT INTO  @T   VALUES ( '#var1','1')

    INSERT INTO  @T   VALUES ( '#var1','1')

    INSERT INTO  @T   VALUES ( '#var2','2')

    INSERT INTO  @T   VALUES ( '#var3','3')

    INSERT INTO  @T   VALUES ( '#var4','4')

    INSERT INTO  @T   VALUES ( '#var5','5')

    INSERT INTO  @T   VALUES ( '#var6','6')

    INSERT INTO  @T   VALUES ( '#var7','7')

    SELECT * FROM @T

    EXEC SP_NUEVO_VAR   @T

Here is the type I have created:

CREATE TYPE  [dbo].[TVARIABLE] AS TABLE

      (

         variable varchar(25),

         valor    varchar(25)

      )

Here is the stored procedure:

 CREATE PROCEDURE SP_NUEVO_VAR

    @T_Variable TVARIABLE READONLY

AS

BEGIN

BEGIN TRAN SAV_VAR

BEGIN TRY

    DECLARE @Output_T TVARIABLE

    DECLARE @variable       as varchar(50),

            @valor          as varchar(50),

            @folio_terminal as int,

            @new_var        as int,

            @sp             as varchar(50),

            @LOG            AS VARCHAR(Max)  



    DECLARE VARIABLES CURSOR FOR SELECT * FROM  @T_Variable;

     SET @sp='SP_NUEVO_VAR'

     EXEC SP_LOGDB 'START',@sp



    SELECT @folio_terminal = folio_terminal FROM terminal 

    --WHERE no_serie=@no_serie



    SET @LOG='@folio_terminal:['+CAST(@folio_terminal AS VARCHAR(10))+']'

     EXEC SP_LOGDB 'START',@sp



    OPEN VARIABLES

    FETCH NEXT FROM VARIABLES INTO @variable,@valor

      WHILE @@FETCH_STATUS = 0

       BEGIN

              SELECT @new_var=NEXT VALUE FOR dbo.seq_variable;   

              INSERT INTO dbo.variables (id_var,   folio_terminal,  variable,   valor)

              VALUES                    (@new_var, @folio_terminal, @variable, @valor) 

              FETCH NEXT FROM VARIABLES INTO  @variable,@valor

       END

       COMMIT TRAN SAV_VAR

END TRY

BEGIN CATCH

    ROLLBACK TRAN SAV_VAR

END CATCH 

END

COMMIT

GO

When I run the implmentation I get this error:

Mens 2766, Nivel 16, Estado 4, Procedimiento SP_NUEVO_VAR, Línea 12

La definición del tipo de datos definido por el usuario 'TVARIABLE' ha cambiado.

The error in English is that the type of data defined by the user 'TVARIABLE' has changed.

When I use this stored procedure from C#, the stored procedure works FINE, but running the procedure in T-SQL is not working.

Sorry, I haven't noticed about something:

I use a script to erase all the database, to start all from zero, this script is useful to test my stored procedures, so in the stored procdure
SP_NUEVO_BD (in the code below), I drop the stored procedure SP_NUEVO_VAR, I drop the type TVariable, then I create the type, then I create the stored procedure.

Something is happening that I cannot run the full script, but when I run it individually it works:

Here is the script below:

USE foxtrot

EXEC sp_configure 'show advanced options', 1

GO

-- To update the currently configured value for advanced options.

RECONFIGURE

GO

-- To enable the feature.

EXEC sp_configure 'xp_cmdshell', 1

GO

-- To update the currently configured value for this feature.

RECONFIGURE

GO

-- Nueva Base de datos

SET NOCOUNT ON

EXEC SP_NUEVO_DB 



-- Script de ejemplo, variables de ejemplo 



DECLARE @no_serie as varchar (20),

        @folio_terminal as int,

        @err_cod as int,

        @folio_solicitud as int

        SET @no_serie='282-716-200'



-- Tabla de ejemplos de nuevas variables



-- Nuevo Registro de terminal ùnica



EXEC SP_NUEVO_TERMINAL   @no_serie, @folio_terminal OUT, @err_cod OUT



PRINT 'No de serie:['   +@no_serie+']' PRINT 'Folio terminal:['+CAST(@folio_terminal as varchar(20))+ ']' PRINT '@err_cod:['+CAST(@err_cod as varchar(20))+']'



-- Nuevo Registro de terminal, con sistema operativo, modelo  



EXEC SP_NUEVO_REGISTRO_TERMINAL 'T00001','282-716-200','QTG5001','EOS123','VX610', @err_cod OUTPUT



PRINT 'err_cod:['+CAST(@err_cod as varchar(20))+']'



-- Script de nuevas variables 



DECLARE @T TVARIABLE 

INSERT INTO  @T   VALUES ( '#var1','1')

INSERT INTO  @T   VALUES ( '#var2','2')

INSERT INTO  @T   VALUES ( '#var3','3')

INSERT INTO  @T   VALUES ( '#var4','4')

INSERT INTO  @T   VALUES ( '#var5','5')

INSERT INTO  @T   VALUES ( '#var6','6')

INSERT INTO  @T   VALUES ( '#var7','7')

--SELECT * FROM @T

EXEC SP_NUEVO_VAR   @T_Variable=@T

Yu can see that the implmentation I refer in the first post is at the end of the script, when I executed indivudually it works fine, but when I run the complete script it doesn´t, considering I make all the process of deleting the stored procedure and the type, then I recreate it.
