php - Brackets in Doctrine query -

hi have nest or / , conditions need brackets in sql statement in right order how make this

is should in form (... or ...) , ...

thnx

according blog post, "solving doctrine parenthesis problem", need $query->where("(conditiona or conditionb) , conditionc");

that may like:

doctrine_query::create()     ->from(...)     ->where('a = ? or b = ?', array(vala, valb))     ->andwhere('c = ?', valc);

the poster does, however, provide more generic solution, whereparenwrap(), extending doctrine_query:

dq::create() ->from(...) ->where('a = ?', vala) ->orwhere('b = ?', valb) ->whereparenwrap() ->andwhere('c = ?', valc);

TY
