Description:
------------
We just recently upgraded from Oracle 10g to Oracle 11g.  Since that move the ocicolumnscale and ocicolumnprecision functions have stopped returning the column length.  

Windows 2003 Enterprise Server
Zend Core 2.5.0
PHP 5.2.5

Reproduce code:
---------------
//  mynumber field is a 10,4 decimal
$sql = "SELECT mynumber FROM TABLENAME";
$R = OCIParse($c, $sql);
OCIExecute($R);
while (OCIFetch($R)) {
     $column_type  = ocicolumntype($R, $i);
     if( $column_type == "NUMBER" )
     {
          print ocicolumnscale($R, $i ) . "\n";
          print ocicolumnprecision($R, $i ) . "\n";
     }
}




Expected result:
----------------
Should Return

10
4

Actual result:
--------------
Returns

0
0

What's the version of the Oracle client libraries used by PHP?
What platform is the DB on?
Are client/server 32bit or 64bit?
What does phpinfo() show for the OCI8 "Revision"? (The problem could be related to http://bugs.php.net/bug.php?id=41917)

I've connected my code to both an 10g and 11g database the they both are returning the same incorrect data.  Is there a way for me to debug what is actually being returned? 

I've looked in the all_tab_columns table in both a 10g and 11g databases and the information is correct.  I'm also looking at a VARCHAR2  field that returns 0 as the field size.  In the table it shows it as a 18 char string but both ocicolumnscale(..) and ocicolumnprecision(..) return 0 and 0;

I've found a workaround for myself by querying the the all_tab_columns table but that is just a work around.  I 100% certain this worked months back but only assumed it was the 11g issue.  I'm not quite sure how to proceed on finding out what is wrong.

Oracle Client
10.2.0

Oracle Server
Windows 2003 Enterprise Server 32 Bit

Thank you for your bug report. This issue has already been fixed
in the latest released version of PHP, which you can download at 
http://www.php.net/downloads.php



In your version of OCI8 you don't have the fix for http://bugs.php.net/bug.php?id=41917

(i) try testing with PHP 5.2.6+ from php.net
(ii) ping Zend about updating OCI8 in ZCO (this is planned, but the schedule might have changed recently)
