更改SQL Server Compact 4.0的排序规则

Question

Is it somehow possible to change collation of a .sdf-file? I have tried Management Studio 2008 but it only supports version 3.5, Management Studio 2012 does not support SQL Server Compact at all as far as I can see, the SQL Server Compact Toolbox for Visual Studio does not seem to offer this possibility and ALTER DATABASE also seems to be missing - is there any solution at all?

Answer 1

Yes, there is a solution, the SqlCeEngine Compact method allows you to do that from code (it effectivly recreates the database file), or you can do it via my sqlcecmd command line utility.

sqlcecmd -d "Data Source=C:\data\mydb.sdf" -z "Data Source=;LCID=1044"

I think that in order to change the collation on a .sdf file you will need to re-create it as a database in SQL Server:

USE master
GO
CREATE DATABASE "file.sdf" DATABASEPASSWORD '<Pwd>' COLLATE <the_Collation>
GO

If you have it already established as a database then you just need to alter the database:

USE master
GO
ALTER DATABASE <the_Database>
COLLATE <new_Collation>
GO

Then you can re-compact the database and it will have the collation you require.
