PreparedStatement module
NextResult tries to retrieve the next result from preparedstat. If there are no results available, it returns NULL.
If a result is available, it will be an integer corresponding to an update statement, or a Result module corresponding to a query statement.
To issue a multi-statement SQL string, the Execute command must be used.
Some databases may require the processing of the current result be completed before the next result is returned by NextResult.
