    Description

      Many built-in SQL functions and operators use long as internal representation of Timestamp type and only support millisecond precision. This ticket will check fix it and let them support nanosecond precision. The related SQL functions and operators are: 

      • timestamp compare
      • timestamp +/- interval
      • extract function
      • timestampadd/timestampdiff function
      • to_timestamp function
      • cast between timestamp with different precision
