These new number format elements have been added to SQL for Oracle7:
These new date format elements have been added to SQL for Oracle7:
If you used National Language Support in Oracle Version 6, the WW date format element may behave differently in Oracle7. In Version 6, depending on the territory component of the value of the LANGAUGE initialization parameter, WW returned a week number based on either the ISO standard or the number of days from January 1. In Oracle7, WW always returns a week number based on the number of days from January 1, regardless of the value of the NLS_TERRITORY initialization parameter, and the new IW date format element returns the ISO standard week number. If your Version 6 application used WW to return the ISO standard week number, replace WW with IW.
Oracle7 also has a new format model modifier FX and new functionality for the FM format model modifier. For information on format models, see the section "Format Models" .
