Description:
------------
The db2_columns function does not send any description of columns with a table which name is in lower case. On window system, this function work fine. 
DB2 tables where created in lowercase name for using with CakePHP. 

We're using Lampp on Linux for our developpment.

Reproduce code:
---------------
SQL 
create table TEST."sample"
(
  "id"            INTEGER not null generated BY DEFAULT AS identity (NO CACHE, INCREMENT BY 1),
  "title"         VARCHAR(50),
  "created"       TIMESTAMP DEFAULT CURRENT TIMESTAMP,
  constraint P_USERS_U1 primary key ("id")
);


PHP
...
$stmt = db2_columns ($conn ,null , 'TEST' , 'sample' , '%' );
if ( $stmt ) 
{
  while ($rowC = db2_fetch_assoc($stmt)) 
  {
    var_dump( $rowC );
  }
}

Expected result:
----------------
Arrays of columns description 'sample' table.

Actual result:
--------------
None
