Class TimeSlice

java.lang.Object
dev.frostlake.functions.BuiltInFunction
dev.frostlake.functions.scalar.datetime.TimeSlice

public class TimeSlice extends BuiltInFunction
TIME_SLICE(t, n, unit [, 'START'|'END']) — the start (default) or end of the n-unit bucket containing t. Second/minute/hour/day/week buckets align on the epoch (weeks on Monday 1970-01-05 per Snowflake); month/quarter/year buckets count calendar months from 1970-01.

    • evaluate

      public Object evaluate(List<Object> args)
      Description copied from class: BuiltInFunction
      Computes the function's result over its already-evaluated argument values. A SQL NULL argument arrives as Java null, and returning null makes the SQL result NULL.
      Specified by:
      evaluate in class BuiltInFunction
      Parameters:
      args - the argument values, in call order
      Returns:
      the function's value for these arguments, or null for SQL NULL
    • getMinArgCount

      public int getMinArgCount()
      Description copied from class: BuiltInFunction
      The fewest arguments a call to this function may pass; fewer is an argument-count error.
      Specified by:
      getMinArgCount in class BuiltInFunction
      Returns:
      the minimum accepted argument count
    • getMaxArgCount

      public int getMaxArgCount()
      Description copied from class: BuiltInFunction
      The most arguments a call to this function may pass; Integer.MAX_VALUE marks a variadic function (see BuiltInFunction.isVariadic()).
      Specified by:
      getMaxArgCount in class BuiltInFunction
      Returns:
      the maximum accepted argument count
