I am getting the following error itermittently on a SQLBulkCopy. I have search Google high and low, but it looks like I may be the only one to ever get it given the Google result set I received... Any idea why this is happening?System.IndexOutOfRangeException: Index was outside the bounds of the array. at System.Data.SqlClient.SqlDataReader.GetLocaleId(Int32 i) at System.Data.SqlClient.SqlBulkCopy.AnalyzeTargetAndCreateUpdateBulkCommand(BulkCopySimpleResultSet internalResults) at System.Data.SqlClient.SqlBulkCopy.WriteToServerInternal() at System.Data.SqlClient.SqlBulkCopy.WriteRowSourceToServer(Int32 columnCount) at System.Data.SqlClient.SqlBulkCopy.WriteToServer(IDataReader reader) at DEER_DAQ.modFunctions.SQLBulkCopyCode() Public Sub SQLBulkCopyCode() Dim tempReader As SqlDataReader Dim BufferRowCount As UInt16 Try If inSQLBulkCopyCode Then Exit Sub inSQLBulkCopyCode = True While SQLBufferConn.State <> Data.ConnectionState.Open PostMessageToStatusTab(vbNewLine & "Lost Connection to SQLBufferConn") If ConnectToSQL(2) Then PostMessageToStatusTab(vbNewLine & "Restablished Connection to SQLBufferConn") Else PostMessageToStatusTab(vbNewLine & "Unable to Restablish Connection to SQLBufferConn") End If System.Threading.Thread.Sleep(500) End While While SQLDataConn.State <> Data.ConnectionState.Open PostMessageToStatusTab(vbNewLine & "Lost Connection to SQLDataConn") If ConnectToSQL(1) Then PostMessageToStatusTab(vbNewLine & "Restablished Connection to SQLDataConn") Else PostMessageToStatusTab(vbNewLine & "Unable to Restablish Connection to SQLDataConn") End If System.Threading.Thread.Sleep(500) End While ' Get the number of rows in the buffer table SQLBufferReadCmd = New SqlCommand("SELECT COUNT(*) FROM " & TestCell, SQLBufferConn) BufferRowCount = SQLBufferReadCmd.ExecuteScalar ' Get all rows from the buffer (should be 100) SQLBufferReadCmd = New SqlCommand("SELECT * FROM " & TestCell, SQLBufferConn) tempReader = SQLBufferReadCmd.ExecuteReader If Not SQLBulkCopyFirstRun Then Dim TempCount As UInt16 ' Create bulk copier SQLBulkCopier = New SqlBulkCopy(SQLDataConn) SQLBulkCopier.DestinationTableName = TestCell ' Map column headers properly For TempCount = 0 To tempReader.FieldCount - 1 SQLBulkCopier.ColumnMappings.Add(tempReader.GetName(TempCount), tempReader.GetName(TempCount)) 'PostMessageToStatusTab(tempReader.GetName(TempCount)) Next SQLBulkCopyFirstRun = True End If ' Start the bulk copy SQLBulkCopier.BatchSize = BufferRowCount SQLBulkCopier.WriteToServer(tempReader) ' Delete all data from the buffer table SQLBufferReadCmd = New SqlCommand("DELETE FROM " & TestCell, SQLBufferConn) SQLBufferReadCmd.ExecuteNonQuery() ' Reset the buffer size counter SQLBufferSize = 0 Catch ex As Exception SQLBulkCopyError = True PostMessageToStatusTab("Error in SQL bulk Copy!" & vbNewLine & vbNewLine & ex.ToString) TextMessage("Error in SQL bulk Copy!" & vbNewLine & vbNewLine & ex.ToString) Finally inSQLBulkCopyCode = False tempReader.Close() End Try End sub
