>   url = urlWithUserAndPass,
>   table = "TEST.seq",
>   columnName = "id",
>   lowerBound = 0,
>   upperBound = 4,
>   numPartitions = 0,
>   connectionProperties = new Properties)
> {noformat}
> Currently, Spark SQL generates wrong results due to wrong partitions:
> {noformat}
>   Part 0 id < 3 or id is null
>   Part 1 id >= 3 AND id < 2
>   Part 2 id >= 2
