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)
)

value_sz is set to allow for character set conversion due to different client and 
server character sets.  This might increase the storage requirements when the 
data is stored in the server. The hardcoded choice of the ratio is questionable.

You can get around this by adding the size to the bind statement:

$sth->bindValue(':p1', $big_value, PDO::PARAM_STR, 4000);
