Date Functions

The transformation language includes a group of date functions to round, truncate, or compare dates, extract one part of a date, or perform arithmetic on a date.
You can pass any value with a date datatype to any of the date functions. However, if you want to pass a string to a date function, you must first use the TO_DATE function to convert it to a transformation Date/Time datatype.
The transformation language includes the following date functions:
  • ADD_TO_DATE
  • DATE_COMPARE
  • DATE_DIFF
  • GET_DATE_PART
  • IS_DATE
  • LAST_DAY
  • MAKE_DATE_TIME
  • MAX
  • MIN
  • ROUND(Date)
  • SET_DATE_PART
  • SYSTIMESTAMP
  • TO_CHAR(Date)
  • TIME_RANGE
  • TRUNC(Date)
Several of the date functions include a
format
argument. You must specify one of the transformation language format strings for this argument. Date format strings are not internationalized.
The Date/Time transformation datatype supports dates with precision to the nanosecond.
