问题 At home, I have SQL Server 2008 R2 (Express) installed which is attached to a certain .mdf file. I'm in the process of installing SQL Server 2012 (Developer Edition). Can I attach 2012 to the same .mdf file? Logically, it seems like this would work as long as only one of the two instances of SQL Server is running. Thoughts? 回答1: You can go upwards - from an older version to a newer one, e.g. you can backup your database in 2008 R2 and restore that backup in your 2012 instance - but you CANNOT

问题 I have a query that uses 3 functions and a few different views beneath it, which are too complex to post here. The odd thing I am experiencing is when running the top level query, having more than 1 search key is causing the query to take around an hour to run, where splitting the query in two takes about 5 seconds per query. Here is the top level query: Select * from dbo.vwSimpleInvoice i inner join dbo.vwRPTInvoiceLineItemDetail d on i.InvoiceID = d.InvoiceID When I add this where clause:
