Fatal error: Cannot use object of type stdClass as array in sites\all\modules\domain\domain.module on line 1080

update: use oracle $domain is stdClass object
but use mysql $domain is null

so what should to do? I'm not familiar with code. and why there is no error use mysql.

update: and you said It's oracle driver bug in another duplicate issue I post.

update:
$result = db_query("SELECT domain_id, subdomain, sitename, scheme, valid, weight, is_default, machine_name FROM {domain}", array(), array('fetch' => PDO::FETCH_ASSOC))->fetchAllAssoc('domain_id');
$result return different use oracle or mysql

mysql

array(1) (
  [1] => array(8) (
    [domain_id] => (string) 1
    [subdomain] => (string) fbw.com
    [sitename] => (string) fbw
    [scheme] => (string) http
    [valid] => (string) 1
    [weight] => (string) -1
    [is_default] => (string) 1
    [machine_name] => (string) fbw_com
  )
)

but oracle

array(1) (
  [0] => stdClass object {
    domain_id => (string) 0
    subdomain => (string) fbw.com
    sitename => (string) fbw.com
    scheme => (string) http
    valid => (string) 1
    weight => (string) -1
    is_default => (string) 1
    machine_name => (string) fbw_com
  }
)

change
$result = db_query("SELECT domain_id, subdomain, sitename, scheme, valid, weight, is_default, machine_name FROM {domain}", array(), array('fetch' => PDO::FETCH_ASSOC))->fetchAllAssoc('domain_id');
to
$result = db_query("SELECT domain_id, subdomain, sitename, scheme, valid, weight, is_default, machine_name FROM {domain}", array(), array('fetch' => PDO::FETCH_ASSOC))->fetchAllAssoc('domain_id',PDO::FETCH_ASSOC);

It's work!

=================================
update: not work!

use oracle return:

array(1) (
  [0] => array(8) (
    [domain_id] => (string) 0
    [subdomain] => (string) fbw.com
    [sitename] => (string) fbw.com
    [scheme] => (string) http
    [valid] => (string) 1
    [weight] => (string) -1
    [is_default] => (string) 1
    [machine_name] => (string) fbw_com
  )
)

mysql return:

array(1) (
  [1] => array(8) (
    [domain_id] => (string) 1
    [subdomain] => (string) fbw.com
    [sitename] => (string) fbw
    [scheme] => (string) http
    [valid] => (string) 1
    [weight] => (string) -1
    [is_default] => (string) 1

  )
)
