The Sys_Calendar.CALENDAR system view helps to extend the properties of a DATE data type column by means of a join. The columns of the view contain data only for the active calendar for the session.
The calendar dates range from 1900 to 2100 and are stored in a table in the Sys_Calendar database.
The administrator must run DIPCAL SQL and DIPSYSFNC scripts from the DIP utility to create the Sys_Calendar database and the versions of the Calendar view.
- Sys_Calendar.CALENDAR_TD_ISO_COMPATIBLE (view used for the current release)
- Sys_Calendar.CALENDAR_TD1310 (legacy view that uses arithmetic to compute column values)
Sys_Calendar.CALENDAR and Sys_Calendar.CALENDAR_TD_ISO_COMPATIBLE have the same definition after running the DIP utility.
The current version (Sys_Calendar.CALENDAR_TD_ISO_COMPATIBLE) is an internal view and can only be accessed by user DBC.
