    Intervals in jOOQ

    +

    + jOOQ fills a gap opened by JDBC, which neglects an important SQL data type as defined by the SQL standards: INTERVAL types. SQL knows two different types of intervals: +

    +
      +
    • YEAR TO MONTH: This interval type models a number of months and years
      • +
    • DAY TO SECOND: This interval type models a number of days, hours, minutes, seconds and milliseconds
      • +
    + +

    + Both interval types ship with a variant of subtypes, such as DAY TO HOUR, HOUR TO SECOND, etc. jOOQ models these types as Java objects extending : (where Number.intValue() corresponds to the absolute number of months) and (where Number.intValue() corresponds to the absolute number of milliseconds) +

    + +

    Interval arithmetic

    +

    + In addition to the documented previously, interval arithmetic is also supported by jOOQ. Essentially, the following operations are supported: +

    +
      +
    • DATETIME - DATETIME => INTERVAL
      • +
    • DATETIME + or - INTERVAL => DATETIME
      • +
    • INTERVAL + DATETIME => DATETIME
      • +
    • INTERVAL + - INTERVAL => INTERVAL
      • +
    • INTERVAL * or / NUMERIC => INTERVAL
      • +
    • NUMERIC * INTERVAL => INTERVAL
      • +
    +     +
