$arr = [
        ["рр","ыы","ыаы",20,"ыаы",2],
        ["ыпв","ып","вп",9,"впрр",4],
        [ "вр","вр","вр",30,"вр",5],
        ["врар","ароа","аоао",50,"ааоао",12]
    ];


    for($i = 0; $i < count($arr); $i++)
    {
        for($j = 0; $j < count($arr[$i]); $j++)
        {
        }
    }

WHERE YEAR(hire_date) IN (
SELECT MAX(salary), YEAR(hire_date)

вложенный селект вернет ДВА столбца, и как sqlю быть с этим?
