Description:
------------
Using PDO/OCI via Yii framework. Inserts/updates to varchar2(4000) column fail with error ORA-01461 when value exceeds 1332 characters. 

Line 300 of source php-5.4.9/ext/pdo_oci/oci_statement.c:

value_sz = 1332; /* maximum size before value is interpreted as a LONG value */

Why???  

I changed to "value_sz = 4000", recompiled, and inserts/updates work fine. I'm not using CLOBs, only varchar2() columns. 


Test script:
---------------
$dbh = new PDO($dsn, $dbuser, $dbpass);
 
$sth = $dbh->prepare('insert into some_table (some_varchar4000_column) values (:p1)');
 
$big_value = str_repeat('ABCDEFGHIJ', 300);
$sth->bindValue(':p1', $big_value, PDO::PARAM_STR);
 
$sth->execute();
print_r($sth->errorInfo());


Expected result:
----------------
Array
(
    [0] => 00000
    [1] => 
    [2] => 
)


Actual result:
--------------
Array
(
    [0] => HY000
    [1] => 1461
    [2] => OCIStmtExecute: ORA-01461: can bind a LONG value only for insert into a LONG column
 (/usr/local/src/php-5.4.5/ext/pdo_oci/oci_statement.c:146)
