21 | NLS_Date_Format |
---|
22 | Allows you to use a date format other than the Oracle Lite default. When a literal |
---|
23 | character string appears where a date value is expected, the Oracle Lite database |
---|
24 | tests the string to see if it matches the formats of Oracle, SQL-92, or the value |
---|
25 | specified for this parameter in the POLITE.INI file. Setting this parameter also |
---|
26 | defines the default format used in the TO_CHAR or TO_DATE functions when no |
---|
27 | other format string is supplied. |
---|
28 | |
---|
29 | For Oracle the default is dd-mon-yy or dd-mon-yyyy, and for SQL-92 the default is |
---|
30 | yy-mm-dd or yyyy-mm-dd. |
---|
31 | |
---|
32 | Using 'RR' in the format forces two-digit years less than or equal to 49 to be |
---|
33 | interpreted as years in the 21st century (20002049), and years over 50 as years in |
---|
34 | the 20th century (19501999). Setting the RR format as the default for all two-digit |
---|
35 | year entries allows you to become year-2000 compliant. For example: |
---|
36 | NLS_DATE_FORMAT='RR-MM-DD' |
---|
37 | |
---|
38 | You can also modify the date format using the ALTER SESSION command. |
