-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.

- Time 0.6081s (1644.60 inserts/sec) with direct OCIParse/OCIExecute
- Time 0.6341s (1577.16 inserts/sec) with ADOdb Prepare/Bind/Execute
- Time 1.5533s ( 643.77 inserts/sec) with pure SQL using Execute
