I try to create and chain expression with different conjunction, but it seems I do not undertood how does it work.
$e = new QueryExpression();
$e->add(['OR' => '1=2']);
$e->add(['AND' => '7=8']);
The result of the abode is
(1=2 AND 3=4 AND 5=6 AND 7=8)
Ho do I add AND and OR conjunctions?
there was orWhere() and andWhere() which I was use
but there is also info that they are deprecated.
The way I found is that you have to create a new QueryExpression for every part of it
$query->newExpr('3 = 4')
->add($query->newExpr('7 = 8');
