NLS_Date_Format
|
|
|
29 |
Allows you to use a date format other than the Oracle Lite default. When a literal
|
|
|
30 |
character string appears where a date value is expected, the Oracle Lite database
|
|
|
31 |
tests the string to see if it matches the formats of Oracle, SQL-92, or the value
|
|
|
32 |
specified for this parameter in the POLITE.INI file. Setting this parameter also
|
|
|
33 |
defines the default format used in the TO_CHAR or TO_DATE functions when no
|
|
|
34 |
other format string is supplied.
|
|
|
35 |
|
|
|
36 |
For Oracle the default is dd-mon-yy or dd-mon-yyyy, and for SQL-92 the default is
|
|
|
37 |
yy-mm-dd or yyyy-mm-dd.
|
|
|
38 |
|
|
|
39 |
Using 'RR' in the format forces two-digit years less than or equal to 49 to be
|
|
|
40 |
interpreted as years in the 21st century (2000-2049), and years over 50 as years in
|
|
|
41 |
the 20th century (1950-1999). Setting the RR format as the default for all two-digit
|
|
|
42 |
year entries allows you to become year-2000 compliant. For example:
|
|
|
43 |
NLS_DATE_FORMAT='RR-MM-DD'
|
|
|
44 |
|
|
|
45 |
You can also modify the date format using the ALTER SESSION command.

* The FIRST_ROWS hint explicitly chooses the approach to optimize response

739 |
* time, that is, minimum resource usage to return the first row. Results

* As this uses complicated sql statements, we only use this if $offset >= 100.

* This idea by Tomas V V Cox.

* class will be used.

1172 |
* Some timings to insert 1000 records, test table has 3 cols, and 1 index.
|
|
|
1173 |
* - Time 0.6081s (1644.60 inserts/sec) with direct oci_parse/oci_execute
|
|
|
1174 |
* - Time 0.6341s (1577.16 inserts/sec) with ADOdb Prepare/Bind/Execute
|
|

1175 |
* - Time 1.5533s ( 643.77 inserts/sec) with pure SQL using Execute
|
|
|
1176 |
*
|

1177 |
* Now if PHP only had batch/bulk updating like Java or PL/SQL...
|
|

*
|

1179 |
