Ejecutar una consulta como la lista a continuación, a partir de ella se puede ver:
- esquema nombre
- nombre de tabla/vista
- tipo de tabla (como: SYSTEM_TABLE, VIEW, SQL_TABLE_VALUED_FUNCTION, USER_TABLE, SQL_INLINE_TABLE_VALUED_FUNCT ION, INTERNAL_TABLE)
- nombre de la columna
- columna de tipo de datos (incluyendo longitud, precisión, etc)
- Anulabilidad
- la posición de esta columna en la clave principal
- completa clave principal, todas las columnas de PK concatenan juntos, si esta columna es parte de la PK
- de identidad (semilla, incremento y valor actual)
- cheque definición de restricción
- defini columnas calculadas ción

Puede eliminar el comentario de la WHERE para filtrar por el esquema/tabla/columna.
También puedes, simplemente crear un trigger para que le avise de los cambios:
create this log table first:
CREATE TABLE YourLogTable (EventID int not null identity(1,1), EventDateTime datetime null, EventDescription varchar(MAX) null)
USE [TheDatabase]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER [YourDatabaseTrigger]
ON DATABASE
FOR DDL_DATABASE_LEVEL_EVENTS --DDL_TABLE_EVENTS --DDL_EVENTS
AS
DECLARE @EventData xml
DECLARE @Message varchar(1000)
SET @EventData=EVENTDATA()
INSERT INTO YourLogTable
(EventDateTime,EventDescription)
VALUES (GETDATE(),--SUSER_NAME()
--+'; '[email protected]('(/EVENT_INSTANCE/ObjectType)[1]', 'varchar(500)')
--+'; '[email protected]('(/EVENT_INSTANCE/ObjectName)[1]', 'varchar(500)')
--+'; '[email protected]('(/EVENT_INSTANCE/TSQLCommand/CommandText)[1]','nvarchar(8000)')
CONVERT(varchar(max),@EventData)
)
RETURN
GO
SET ANSI_NULLS OFF
GO
SET QUOTED_IDENTIFIER OFF
GO
ENABLE TRIGGER [YourDatabaseTrigger] ON DATABASE
que le permitirá ver todos los cambios realizados a la base de datos.
Esto es realmente genial. No utilicé tu código como tal, pero me abrió muchas puertas, lo cual es mejor que simples modismos y scripts. – MetaHyperBolic
