问题
I'm using a SQL Server CE database via Microsoft's OLEDB 3.5 SQL CE Driver. Here's my connection string:
Provider=Microsoft.SQLSERVER.CE.OLEDB.3.5;Data Source=C:\Users\me\Desktop\test1.sdf
This query works fine:
SELECT Thing FROM OtherThing WHERE name = 'TextThing'
This query fails:
SELECT Foo FROM Stuff
And this is the error I get:
Multiple-step operation generated errors. Check each status value.
The only structural difference in the table themselves is that one has a text primary key and the other has a bigint identity field as a primary key.
What I've tried:
- http://support.microsoft.com/kb/269495 (neither of the resolution conditions are true for me)
- Switched the cursorLocation property from adUseClient to adUseServer (this caused none of my queries to work - same error). That said, I think maybe I shouldn't give up on this one (thoughts?).
回答1:
The problem has to do with the fact that the tables that caused that exception to be thrown were ones with fields of type nvarchar and sizes of 255. I changed those to ntext or reduced the size to 100 and no exception was thrown.
