Sql-server – SQL server 2005 backup statistic

I don't know which version of NH you're using, but I'm using 3.1 with SQL 2008 and it does not have any special features to handle Parameter Sniffing. I know this because I've suffered quite a bit trying to overcome this issue.

I don't know if you use HQL/Criteria/QueryOver/LINQ, but I found two ways to (kind of) solve this:

• Appending "option(recompile)" on the query -> with an hook on the query execution if you're using the likes of QueryOver/LINQ.

Although this works, it no longer fetches existing query plans from the cache, and every query has to build it ground-up.

• Conditionally, add a dummy predicate to the query

Or something that would force a different query plan to be fetched. For example, if the date interval is less than a month add a .Where(x => true). It would then have a different plan for large intervals and a plan for small intervals.

First there's no way using the native tools to mount a backup file and read the data in it. That said, what you can do is write your version information into the description of the backup using the DESCRIPTION keyword. Then read this information using the RESTORE DATABASE WITH HEADERONLY to get the information and make sure that they have the correct version.
