+Summary: OdbcDataAdapter.Fill method returns empty DataTable
+
+Description of Problem:
+OdbcDataAdapter.Fill() method returns DataSet with DataTable with zero 
+rows filled.
+
+Steps to reproduce the problem:
+Run following code with created ODBC connection and database filled with 
+some data.
+
+Dim connStr As String = "DSN=xxx;UID=xxx;PWD=xxx"
+Dim sqlStr As String = "select * from xxx"
+
+Dim conn As IDbConnection conn = New OdbcConnection(connStr)
+conn.Open()
+Dim command As IDbCommand = conn.CreateCommand()
+command.CommandText = sqlStr
+
+Dim dataAdapter As IDbDataAdapter = New OdbcDataAdapter
+Dim ds As New DataSet
+dataAdapter.SelectCommand = command
+dataAdapter.FillSchema(ds, SchemaType.Source)
+Dim rowsFilled As Integer = dataAdapter.Fill(ds)
+
+Dim dt As DataTable
+For Each dt In ds.Tables
+   Console.WriteLine("dt: " & dt.TableName & "  rowsCount: " & 
+dt.Rows.Count)
+Next
+
+Actual Results:
+dt: xxx rowsCount: 0
+
+Expected Results:
+dt: xxx rowsCount: 5
+
+How often does this happen? 
+Always when OdbcDataAdapter is used to fill DataSet with data.
+
+Additional Information:
+For the SqlDataAdapter method Fill works fine.
+I performed tests with OdbcDataAdapter for SQLServer and Progress 
+databases for Mono under Linux and Windows and results are the same: both 
+return non-filled DataTable.
