Comparing Databases On SQL Server Instances

Andrew Pruski has written a quick comparison script to check if two instances have the same set of databases or the same configuration settings:

For instance, last week I was working with two instances that contained databases part of an Always On availability group and needed to ensure that all databases on the primary were on the secondary.

Now I know there’s a few ways to do this but I needed a quick and easy method as there were over 300 dbs involved.

The method I used to do this implemented the powershell cmdlet Compare-Object

What this does is pretty much what it says on the tin. The cmdlet takes two objects and compares them based on a input property (in this case it’ll be database name).

This can turn into a much more complicated comparison, but Andrew shows that the basic concept is quite straightforward.

So, in Windows PowerShell executing the command […]
