Could not be compared

staggerlee011

Hi all,

I had a table that was corrupt, and a backup with a non-corrupt version. I thought i would be able to use Data Compare to fix the issue doing a compare data and then re-syncing. but when i do a compare pre and post DBCC CHECKDB REPAIR_ALLOW_DATA_LOSS, the results are

"Tables or views could not be compared."

The table that im interested in has a create statement off:

CREATE TABLE [dbo].[NotificationItems](
[NotificationID] [uniqueidentifier] NOT NULL,
[Title] [nvarchar](4000) NOT NULL,
[Description] [nvarchar](max) NULL,
[CreatedAt] [datetime] NOT NULL,
[Ignored] [bit] NOT NULL,
[NotificationTypeID] [uniqueidentifier] NOT NULL,
[varchar](511) NULL,
[AcknowledgedAt] [datetime] NULL,
[AcknowledgedBy] [nvarchar](100) NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

GO

ALTER TABLE [dbo].[NotificationItems] ADD DEFAULT ((0)) FOR [Ignored]
GO

Objects with rows that can not be matched automatically are shown in the Tables or views that could not be compared group. To match rows in the two data sources, SQL Data Compare requires:
•a comparison key for each table or view
•mappings between objects in the data sources

In some cases, SQL Data Compare is unable to map objects and select comparison keys automatically.

You may need to set a custom comparison key or manually map the object.
