RR Format String

RR Format String

The transformation language provides the RR format string to convert strings with two-digit years to dates. Using TO_DATE and the RR format string, you can convert a string in the format MM/DD/RR to a date. The RR format string converts data differently depending on the current year.
  • Current Year Between 0 and 49.
    If the current year is between 0 and 49 (such as 2003) and the source string year is between 0 and 49, the
    PowerCenter Integration Service
    returns the current century plus the two-digit year from the source string. If the source string year is between 50 and 99, the Integration Service returns the previous century plus the two-digit year from the source string.
  • Current Year Between 50 and 99.
    If the current year is between 50 and 99 (such as 1998) and the source string year is between 0 and 49, the
    PowerCenter Integration Service
    returns the next century plus the two-digit year from the source string. If the source string year is between 50 and 99, the
    PowerCenter Integration Service
    returns the current century plus the specified two-digit year.
The following table summarizes how the RR format string converts to dates:
