问题
I have some .SDF tables that are created in a Windows CE app (access table data is passed from a server app, and this is converted into SQL Server Compact records/tables).
I want to look inside them from my desktop machine in Visual Studio 2010. But attempting to create a new Data Connection in the Server Explorer, selecting either of the two "Microsoft SQL Server Compact" Data sources (3.5 and 4.0) fails.
When I choose 3.5 and then "Test Connection," it tells me:
This is not a valid SQL Server Compact Database file or this file version is not supported by current SQL Server Compact Engine.
When I choose 4.0 and then "Test Connection," it tells me:
Incompatible Database Version. If this was a compatible file, run repair. For other cases refer to documentation. [ Db version = 0, Requested version = 0,File name = MyRecalcitrantTable.SDF
Is there a way to make a connection to these tables so I can query them to see what they contain? How can I determine which version they were created with (apparently prior to 3.5) so that I can possibly use an earlier version of VS to view them (or some other tool?)
回答1:
You can use my SQL Server Compact Toolbox VS extension, it has a Detect file version feature, but they are probably version 2.0 files, and can only be opened on a Windows ce device (or emulator)
