Is this OleDbDataAdapter bug
- by ????
It doesn't look to me OleDbDataAdapter should throw an exception on trying to fill DataSet for a db table column of type decimal(28,3). The message is "The numerical value is too large to fit into a 96 bit decimal".
Could you just check this, I have no significant experience with ADO.NET and OLE DB components?
The VB.NET code we have in the application is this:
Dim dbDataSet As New DataSet
Dim dbDataAdapter As OleDbDataAdapter
Dim dbCommand As OleDbCommand
Dim conn As OleDbConnection
Dim connectionString As String
'parts where connectionString is set
conn = New OleDbConnection(connectionString)
'part where sqlQuery is set but it ends up being "SELECT Price As 'Price' From PricebookView" - Price is of type decimal(28,3)
dbCommand = New OleDbCommand(sqlQuery, conn)
dbCommand.CommandTimeout = cmdTimeout
dbDataAdapter = New OleDbDataAdapter(dbCommand)
dbDataAdapter.Fill(dbDataSet)
The last line is where the exception is thrown and the top of the stack trace is:
at System.Data.ProviderBase.DbBuffer.ReadNumeric(Int32 offset)
at System.Data.OleDb.ColumnBinding.Value_NUMERIC()
at System.Data.OleDb.ColumnBinding.Value()

at System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[] datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)
at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior)
at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet)
...
I am not sure why does it try to set the value to Int32.
Thank you for the time !
