What I have tried:

 cmd.CommandText = "insert into CDRReportView Values ('" + Convert.ToInt64(item.cdrRecordType) + "','" + Convert.ToInt64(item.globalCallID_callManagerId) + "','"
                                        + Convert.ToInt64(item.globalCallID_callId) + "','" + Convert.ToInt64(item.origLegCallIdentifier) + "' , '"
                                           + Convert.ToInt64(item.dateTimeOrigination) + "','" + Convert.ToInt64(item.origNodeId) + "','"

The chances of your code succeeding with those statements is not high. Start by extracting the data from the csv into proper groups of items. Make sure that you validate each item as you read it in; your code above will just fail if any item is not a valid number. Once you have all the items read in then you can create a proper INSERT statement, using parameters rather than trying to concatenate integers into strings.
