Enumeration Type Documentation

DateTimeStorage

enum Wt::Dbo::backend::DateTimeStorage

strong

Configuration of date time storage.

The Sqlite3 backend does not provide real type support for date time. Instead, it offers 3 choices for storing a date time, each of these compatible with the use of the built-in arithmetic functions.

Enumerator
ISO8601AsText	As 'text' in ISO8601 format. This also interprets correctly dates stored in the database using the PseudoISO8601AsText format.
PseudoISO8601AsText	As 'text' in ISO8601-like format, but using a space (' ') instead of 'T' as a separator character between date and time. This is the behaviour of Wt::Dbo prior to Wt 3.2.3. This also interprets correctly dates stored in the database using the ISO8601AsText format.
JulianDaysAsReal	As 'real', the number of julian days. Note that this does not support second accuracy for a date time, but is the preferred format for a plain date.
UnixTimeAsInteger	As 'integer', number of seconds since UNIX Epoch.
