Zend Framework gives strange Oracle query

Question

I'm trying to migrate an application from MySQL to Oracle. I'm a newbie to Oracle.
I want the PHP scripts to work on both MySQL and Oracle.
The query I want to do used to be (for MySQL via AdoDB):
SELECT DISTINCT (id)
FROM table1
INNER JOIN table2 ON table1.id = table2.record_id
AND table2.user_id = "XXX"
AND table1.status = table2.status_id
The following code works great for MySQL but generates some strange output for Oracle:
$db = Zend_Db::factory('Oracle', //Mysqli for the MySQL db connection
array(
'host' => 'hostName',
'dbname' => 'dbName',
'username'=> 'userName',
'password'=> 'userPasswd')
$select = $db->select();
$select->distinct();
$select->from(array('i' => 'table1'),array('id'));
$select->joinInner(array('u' => 'table2'),'i.id = u.record_id',array());
$select->where('u.user_id = ?', 'XXX');
$select->where('i.status=u.status_id');
This results in
for MySQL:
SELECT DISTINCT `i`.`id` FROM `table1` AS `i` INNER JOIN `table2` AS `u` ON i.id = u.record_id WHERE (u.user_id = 'XXX') AND (i.status=u.status_id)
this works fine.
for Oracle:
SELECT DISTINCT "i"."id" FROM "table1" "i" INNER JOIN *"table2" "u" ON i.id = u.record_id WHERE (u.user_id = 'XXX') AND (i.status=u.status_id)
this does not work:
ORA-00942: table or view does not exist
when I copy/paste this in SQL developer this gives an error too, complaining about ' *"table2" ' which does not exist.
The only query my SQL developer accepts is :
SELECT DISTINCT i."id" FROM table1 i INNER JOIN table2 u ON i."id" = u."record_id" WHERE (u."user_id" = 'XXX') AND (i."status"=u."status_id")
I have no idea how I can make this query with Zend Framework.
The query should have:
- no quotes around the table names
- quotes around the column names
- no * before the second table name (table2)
Is this a Zend Framework problem or is my Oracle db not very well made?

Answer 1

I believe there are some issues with ZF regarding quoting, e.g. see http://framework.zend.com/issues/browse/ZF-7267 (also note the comment about autoQuoteIdentifier).
I'd review open ZF bugs, upgrade to the latest ZF and report the issue if it still occurs.
At worst case, you may need a branch in your code that manually constructs the query when running against Oracle.
