How can you read table data from your Sql backups.

Postby zaliis » Wed Mar 19, 2014 4:18 am

When I attempt to create an instance of the BackupConnection using the default ctor I get the following error message

SQL Backup Reader may not be called from user code

I also tried using RegisterForDataCompare and opening the BackupConnection and that returns the exception

No filenames specified.

I need to do a schema and data compare between two SQL Server 2008 database backups. If I detect a schema or data difference I need to output the tables in the target database to a Sql CE sdf.

I have the code working to output the database schema I just need to know how to read all records from each table in the backup using the SDK.

I think I can also accomplish what I need if I can compare a sql backup to an empty folder. Then I could read the data I need from the table differences object. But every time I try that type of compare there are no table differences.

Thanks in advance.

You may be creating an object that does not have a constructor meant for public use. If you want to compare data in a backup, here is an example. ... e_database

Hopefully this is useful for you.
