Description:
------------
I have Oracle 8.1.7 working on linux. Some Oracle params:
NLS_RDBMS_VERSION => 8.1.7.2.0
NLS_CHARACTERSET => CL8ISO8859P5
I have table named utf8_test.
SQL> desc utf8_test;
Name Type Nullable Default Comments
---- ------------ -------- ------- --------
ID NUMBER Y
NAME VARCHAR2(10) Y
SQL> select * from utf8_test;
ID NAME
---------- ----------
1 ����
2 ��������
The result of fetching data is depended from NLS_LANG.
When I fetched data from this table a result is depended from NLS_LANG
variable.
1) When I fetch data with NLS_LANG=RUSSIAN_CIS.CL8MSWIN1251 character
set, I receive 2 rows with correct data.
2) When I fetch data with NLS_LANG=RUSSIAN_CIS.UTF8 character set, I
receive 2 rows, with incorrect data. Data in NAME field in 2-nd row is
incorrect (FALSE instead of '��������'). But 1-st row is correct.
I think the problem maybe in the folowing:
This field is defined in database as varchar2(10);
Length of the 1-st row NAME in UTF8 character set is 4*2=8 byte.
(8<10)
Length of the 2-nd row NAME in UTF8 character set is 8*2=16 byte.
(16>10).
Reproduce code:
---------------
<?
// oracle client NLS_LANG=RUSSIAN_CIS.UTF8
$conn = oci_new_connect( 'scott', 'tiger', 'DB' );
$cursor = oci_parse( $conn, 'select id, name from utf8_test' ); //
tested with all oci_fetch_* functions
oci_execute( $cursor, OCI_DEFAULT );
oci_fetch_all( $cursor, $result, 0, -1, OCI_FETCHSTATEMENT_BY_ROW );
print "<pre>";
var_dump($result);
?>
Expected result:
----------------
array(2) {
[0]=>
array(2) {
["ID"]=>
string(1) "1"
["NAME"]=>
string(8) "����"
}
[1]=>
array(2) {
["ID"]=>
string(1) "2"
["NAME"]=>
string(16) "��������"
}
}
Actual result:
--------------
array(2) {
[0]=>
array(2) {
["ID"]=>
string(1) "1"
["NAME"]=>
string(8) "����"
}
[1]=>
array(2) {
["ID"]=>
string(1) "2"
["NAME"]=>
bool(false)
}
}
