CENTURY attribute
The CENTURY
attribute defines expansion
of the year in a DATE
or DATETIME
field.
Syntax
CENTURY = { "R" | "C" |"F" | "P" }
Usage
The CENTURY
attribute specifies how to expand abbreviated one- and two-digit
year specifications in a DATE
and DATETIME
field.
Century expansion is based on this attribute and on the current year defined by the system clock.
The CENTURY
attribute
can specify any of four algorithms to expand abbreviated
years into four-digit year values that end with the same digits (or
digit) that the user has entered.
CENTURY
supports the same settings as the DBCENTURY
environment variable, but
with a scope that is restricted to a single field.
If the CENTURY
and DBCENTURY
settings
are different, CENTURY
takes precedence.
Unlike DBCENTURY
,
the CENTURY
attribute is not case sensitive. However,
we recommend that you use uppercase letters in the attribute.
