[Mono-list] anyone got bDataAdapter.Fill Method work?

[Dennis Boylan]

I'm trying to chase this down myself.  I've got a .NET application which
runs fine under the Microsoft runtime, but I get a:

System.Data.SqlClient.SqlException: Error converting data type nvarchar to tinyint.

while trying to run the same application under mono.

I thought it was fill as well because the traceback looks like this:

in <0x00058> (wrapper remoting-invoke-with-check) System.Data.Common.DbDataAdapter:Fill (System.Data.DataTable)
in [0x00092] (at /home/dennis/Dev/new/DbLayer/Network.cs:1070) IA.DbLayer.DBNetwork:GetDTNetwork (int)

Where GetDTNetwork is trying to fill a DataTable with the values from a
MS SQL database on a remote machine.  It is the last part of my application
code before it gets lost in the weeds.

I thought it might be because the table was empty, so I wrote a little
standalone app to test it.  The standalone app works.

My first test was trying it without using my stored procedure.  It was
called test2.  The second uses a stored procedure like the application
normally does.  It was called test3.

These were my best approximations of what the code at the location was
trying to do.  The real code hides the type of database, so direct examples
would not be all that useful.

Now, mind you, I'm trying this on the bleeding edge.
