Inserting data to a . SDF database (SQL Server Compact Edition connection)

Question

Hi, all.
I'm working on a project that worked fine while connecting to SQL Server 2008. I used a connection string like this:
Driver={SQL Server Native Client 10.0};Server=myServerAddress;Database=myDataBase;Uid=myUsername;Pwd=myPassword;
Now, I've replaced all database connections in my project to work with SQL Server Compact Edition, and my connection string is something like this:
Provider=Microsoft.SQLSERVER.CE.OLEDB.3.5;Data Source=myDir\myDataBase.sdf; 
After changing the type of connection, I'm getting an error on "DB Tools Insert Data.vi". This is what I get:
Error -2147217872 occurred at NI_Database_API.lvlib:Cmd Execute.vi->NI_Database_API.lvlib: DB Tools Insert Data.vi->Main.vi
Possible reason(s):ADO Error: 0x80040E30 Exception occured in Microsoft SQL Server Compact OLE DB Provider: The given type name was unrecognized. [,,,,,] in NI_Database_API.lvlib:Rec Create - Command.vi->NI_Database_API.lvlib:Cmd Execute.vi->NI_Database_API.lvlib: DB Tools Insert Data.vi->Main.vi
This is a simplified block diagram (as I said, it worked perfectly while using SQL Server 2008 connection):
Could you please help me?
Thanks in advance,
Francisco

Hi, Steve. Thanks for your answers.
I worked around this problem by using directly a SQL query instead of this function (you were right, using DBTools Execute Query VI). But now I'm getting problems with other functions, when inserting data into the DB including NULL values.
I make a SQL query like this using DBTools Execute Query VI:
INSERT INTO Table1 (Column1, Column2, Column3, Column4, Column5, Column6) VALUES ('Value1', 'Value2', 'Value3', 'NULL', 'Value5', 'Value6') 
and get the following error:
ADO Error: 0x80040E07Exception occured in Microsoft SQL Server Compact OLE DB Provider: A literal value in the command could not be converted to the correct type due to a reason other than data overflow. [,,,,,] in NI_Database_API.lvlib:Conn Execute.vi->INSERT (new) restricción (DBCT).vi->Restricciones a Base de Datos (DBCT).vi->Definir - editar restricciones.vi->Main.vi
The same SQL query worked perfectly when using the SQL Server 2008 connection, so it's not a database structure issue.
Could somebody please help me?
