On a server I have a SQL Server 2008 r2 standard performing very bad.
To make a quick & dirty test I would like to try to install express edition.
This server is not administrated by me, it is a server of a customer.
A stupid query is not running on that standard SQL Server, it takes 45 minutes to execute, while on my laptop it takes 2 seconds with the same db.
So I suspect either SQL Server is corrupted or windows is corrupted (other ideas?).
This is why I would like to try to install express (to bypass "SQL Server is corrupted").
Is it possible to install express when standard is there?
