| 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. |

---|
| 854 | |
---|

| 865 | Some timings: |
---|
| 866 | ** Test table has 3 cols, and 1 index. Test to insert 1000 records |
---|
| 867 | Time 0.6081s (1644.60 inserts/sec) with direct OCIParse/OCIExecute |
---|
| 868 | Time 0.6341s (1577.16 inserts/sec) with ADOdb Prepare/Bind/Execute |
---|
| 869 | Time 1.5533s ( 643.77 inserts/sec) with pure SQL using Execute |
---|
| 870 | |
---|
| 871 | Now if PHP only had batch/bulk updating like Java or PL/SQL... |
---|
| 872 | |
---|
