TYPO3 Core

Problem occures when using direct_mailSpecial recipient list / special query / "between"

I'm mot sure if this should be fixed in the core or in direct_mail.
I thing it's a core issue.

direct_mail
Recipient List
special query
typ3 "between"

TYPO3 6.2.nn

AND tx_rsmbsttools_newsletter LIKE '%101%' AND tx_rsmbsttools_newsletter LIKE '%%'

TYPO3 7.6.nn

AND tx_rsmbsttools_newsletter LIKE '%101%' AND tx_rsmbsttools_newsletter LIKE *'%#VALUE1#%'*)

The problem is inside the QueryGenerator.php (TYPO3\CMS\Core\Database\QueryGenerator)

6.2.nn

public function getQuerySingle($conf, $first) {
...
if ($conf['comparison'] == 37 || $conf['comparison'] == 36 || $conf['comparison'] *==* 66 || $conf['comparison'] == 67 || $conf['comparison'] == 100 || $conf['comparison'] == 101) {

7.6.nn

public function getQuerySingle($conf, $first){
...
if ($conf['comparison'] === 37 || $conf['comparison'] === 36 || $conf['comparison'] === 66 || $conf['comparison'] === 67 || $conf['comparison'] === 100 || $conf['comparison'] === 101) {

The $conf['comparison'] under 6.7.x will check the type, and the 66 is string-type, so that _$conf['comparison'] === 66 won't match.

The value of $conf['comparison'] is a result from a select list:

<option value="66">contains</option>

So it should be converted to int to let int comparison work.
