@MaxGekk I meet a case

IntervalUtils.fromDayTimeString("2:03:04") throw exception

[info]   Cause: java.lang.IllegalArgumentException: requirement failed: Interval string must match day-time format of '^(?<sign>[+|-])?(?<day>\d+) (?<hour>\d{1,2}):(?<minute>\d{1,2}):(?<second>(\d{1,2})(\.(\d{1,9}))?)$': 2:03:04, set spark.sql.legacy.fromDayTimeString.enabled to true to restore the behavior before Spark 3.0.

It's a But right? since IntervalUtils.fromDayTimeString's comment is

  /**
   * Parse dayTime string in form: [-]d HH:mm:ss.nnnnnnnnn and [-]HH:mm:ss.nnnnnnnnn
   *
   * adapted from HiveIntervalDayTime.valueOf
   */
  def fromDayTimeString(s: String): CalendarInterval = {
    fromDayTimeString(s, DAY, SECOND)
  }

@AngersZhuuuu Is it still WIP? Please, ping me when it is ready.

AngersZhuuuu · 2021-05-01T02:09:25Z

@MaxGekk Can be reviewed now, but currently this method does not seem to be very efficient，Maybe should I add a new method to calculate calculate total microseconds separately?

AngersZhuuuu · 2021-05-01T03:02:55Z

@MaxGekk I think it's ready for review now, but I am confused how can I use
dayTimePattern(DAY -> SECOND) in match case ?

When I write

val regex = dayTimePattern(DAY-> SECOND)

intervalStr match {
    case dayTimePattern(sign, day, hour, minute, secondAndMicro)
.......
}

It can't match, do you know how to match this? If it can be done, we can simplify more code.

Could you check INTERVAL in lower case + spaces:

checkEvaluation(cast(Literal.create("INTERVAL '0 0:0:0' DAY TO SECOND"),

checkEvaluation(cast(Literal.create(" interval '0 0:0:0' Day TO second "),
