SQL Server replication and Change Data Capture (CDC) are powerful features that allow you to replicate and track changes made to your database. However, sometimes you may encounter unexpected errors or situations that can be confusing to troubleshoot.

Recently, one of my followers on Facebook shared an interesting scenario where they faced an error related to replication or CDC. They had a database in their QA environment that was restored from the production environment, which had replication set up. In the QA environment, there was no replication or CDC configured. When they tried to rename a column in a table, they encountered the following error:

Msg 4928, Level 16, State 1, Procedure sp_rename, Line 611
Cannot alter column 'Bar' because it is 'enabled for Replication or Change Data Capture'.

Upon investigation, they verified that none of the tables had CDC enabled or were being tracked by CDC. They also confirmed that replication was disabled using the sp_removedbreplication stored procedure. However, the error message did not align with the verified data points, indicating a potential metadata issue.

After researching online, I came across a workaround that had helped others in similar situations. The workaround involved executing the sp_replicationdboption stored procedure to disable publishing for the database. Unfortunately, this did not resolve the issue.

Considering that the QA database was a restored copy of the production database, I decided to experiment with CDC by enabling and disabling it again. I provided the following script to enable and disable CDC on the table:

USE YOUR_DATABASE_NAME
GO
EXEC sys.sp_cdc_enable_db
GO
EXEC sys.sp_cdc_enable_table @source_schema = N'dbo'
    ,@source_name = N'foo'
    ,@role_name = NULL
    ,@filegroup_name = N'primary'
    ,@supports_net_changes = 1
GO
EXEC sys.sp_cdc_disable_table @source_schema = N'dbo'
    ,@source_name = N'foo'
    ,@capture_instance = N'ALL'
GO
EXEC sys.sp_cdc_disable_db
GO

After executing the above script, they were able to successfully rename the column without encountering any errors.

It’s important to note that encountering unexpected errors or misleading error messages can sometimes be attributed to metadata inconsistencies. In such cases, it’s worth exploring different approaches and workarounds to resolve the issue.
