When writing data to the database the following SQL datatypes are supported.
A list of character codes, or a list of atoms.
For backwards compatibility only, an atom is also accepted, but

compatibility with some ODBC drivers, the integer 0 and 1 are
allowed, meaning "0" and "1".
0 for false, or
1 for true.

date(Year, Month, DayOfMonth), as above.
time(Hour, Minute, Second), as above.
timestamp(Year, Month, Day, Hour, Minute, Second,
