Issue comparing tables using FILESTREAM data

kreitmey

Using SQL server 2012 (11.0.2100), I create the following table in two separate empty databases with FILESTREAM enabled


CREATE TABLE [dbo].[Document_FS](
[DocumentID] [int] IDENTITY(1,1) NOT NULL,
[GuidPK] [uniqueidentifier] ROWGUIDCOL NOT NULL,
[FileName] [varchar](512) NOT NULL,
[FileSize] [bigint] NOT NULL,
[FileDescription] [varchar](255) NULL,
[IsActive] [bit] NOT NULL,
[FileData] [varbinary](max) FILESTREAM NULL,
CONSTRAINT [PK_Documents_FS] PRIMARY KEY CLUSTERED
(
[DocumentID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] FILESTREAM_ON [FILESTREAM],
CONSTRAINT [UQ__Document_FS_GUIDPk] UNIQUE NONCLUSTERED
(
[GuidPK] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] FILESTREAM_ON [FILESTREAM]

GO

SET ANSI_PADDING OFF
GO

ALTER TABLE [dbo].[Document_FS] ADD CONSTRAINT [DF_Document_FS_GuidPK] DEFAULT (newid()) FOR [GuidPK]
GO


On one of the databases, i issue the following command

ALTER TABLE document_fs ADD testAdd1 bigint null

I then do a SQL compare using version 10.4.8.87 against the two databases i created. The deployment script created is as follows

/*
Run this script on:

dbn-sqldev-04\oms.b - This database will be modified

to synchronize it with:

dbn-sqldev-04\oms.a

You are recommended to back up your database before running this script

Any ideas on what is going on, and why I am recieving this error?

Sorry, at this point I don't know what is happening. This is a new error.

I have a backup from another customer experiencing the same problem so once that's up I will let you know what I find.

Brian Donahue

I have found an issue in SQL Compare that happens in SQL 2102 when you have a filestream column with a unique index on it.

If SQL Compare determines there should be a table rebuild, it does not properly construct a temporary index name to use for the index; it uses the index name from the original table instead. So when it tries to rename the index, it cannot find the proper index by name.

This has been logged as bug SC-6439.

Is there an estimate on when this bug will be fixed?
