Description:
------------
I have a column described as:
all_tab_columns.data_type = SDO_GEOMETRY

If I try to select this Column, the following error is generated:

 Error: SQLSTATE[HY000]: General error: 932 OCIStmtFetch: ORA-00932: inconsistent datatypes: expected CHAR got ADT (/usr/local/src/php7.0-7.0.19/ext/pdo_oci/oci_statement.c:497) 

Test script:
---------------
 CREATE TABLE "TEST"."ULITEST" 
   (
	"GEO_ID" NUMBER(38,0), 
	"GEOMETRIE" "MDSYS"."SDO_GEOMETRY" 
);

Insert into TEST.ULITEST (GEO_ID,GEOMETRIE) values (3,MDSYS.SDO_GEOMETRY(2001,31467,MDSYS.SDO_POINT_TYPE(3457079.42,5270387.7,null),null,null));

php > $r = $pdo->query("SELECT * FROM TEST.ULITEST");
php > foreach($r as $row) print_r($row);
PHP Warning:  Uncaught PDOException: SQLSTATE[HY000]: General error: 932 OCIStmtFetch: ORA-00932: inconsistent datatypes: expected CHAR got ADT

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