NLS_Date_Format
|
|
Allows you to use a date format other than the Oracle Lite default. When a literal
|
|
character string appears where a date value is expected, the Oracle Lite database
|
|
tests the string to see if it matches the formats of Oracle, SQL-92, or the value
|
|
specified for this parameter in the POLITE.INI file. Setting this parameter also
|
|
defines the default format used in the TO_CHAR or TO_DATE functions when no
|
|
other format string is supplied.
|
|
|
|
For Oracle the default is dd-mon-yy or dd-mon-yyyy, and for SQL-92 the default is
|
|
yy-mm-dd or yyyy-mm-dd.
|
|
|
|
Using 'RR' in the format forces two-digit years less than or equal to 49 to be
|
|
interpreted as years in the 21st century (2000-2049), and years over 50 as years in
|
|
the 20th century (1950-1999). Setting the RR format as the default for all two-digit
|
|
year entries allows you to become year-2000 compliant. For example:
|
|
NLS_DATE_FORMAT='RR-MM-DD'
|
|
|
|
You can also modify the date format using the ALTER SESSION command.
