I have a table where one of the fields is "InDatabase" (SQL Server "bit" type) which does not allow nulls.

I create a table and add a few hundred rows to it, where InDatabase is always assigned a value (InDatabase refers to whether the row is in another database)

When I call SqlBulkCopy, it is giving me an InvalidOperationException Error, with the message of: 

```
"Column 'InDatabase' does not allow DBNull.Value."

```

Each Row Is Created as such:

```
ProductionDatabaseDataSet.EntriesV2Row NewRow = this.InsertTable.NewEntriesV2Row();

NewRow.MeetEntryID = MeetEntryID;
NewRow.EventID = EventID;
NewRow.MeetID = MeetID;
NewRow.AthleteID = AthleteID;
NewRow.Exhibition = Exhibition;
NewRow.Bonus = Bonus;
NewRow.EnterEvent = true;
NewRow.InDatabase = true;
if (AutoTime != null)
    NewRow.AutoTime = AutoTime ?? -1;
if (CustomTime != null)
    NewRow.CustomTime = CustomTime ?? -1;

this.InsertTable.AddEntriesV2Row(NewRow);

```

Then, after the above is called around 300 times, the SqlBulkCopy is called:

```
SqlBulkCopy bulkCopy = new SqlBulkCopy(this.Connection.ConnectionString);
bulkCopy.DestinationTableName = this.Adapter.TableMappings[0].DataSetTable;
            bulkCopy.BatchSize = BatchSize;
bulkCopy.WriteToServer(InsertTable); //Throwing the error

```

I use this exact same format on about a dozen other tables with no problem.
