Date and time data types

This section examines how date values are handled internally by SQL Anywhere, and how SQL Anywhere handles ambiguous date information, such as the conversion of a two digit year string value.

The following list provides a quick overview of how dates are handled:

  • SQL Anywhere always returns correct values for any legal arithmetic and logical operations on dates, regardless of whether the calculated values span different centuries.
  • At all times, the SQL Anywhere internal storage of dates explicitly includes the century portion of a year value.
  • The operation of SQL Anywhere is unaffected by any return value, including the current date.
  • Date values can always be output in full century format.
