如何将此查询语句变成一条 查询语句
$data = $w -> field('id,picurl') -> select();
foreach ($data as $key => $value)
{
$data[$key]['logoes'] = $wa -> field('id,logo') -> where('classid='.$value['id']) -> select();
}$data = $w -> field('id,picurl') -> select();
foreach ($data as $key => $value)
{
$data[$key]['logoes'] = $wa -> field('id,logo') -> where('classid='.$value['id']) -> select();
}

$data = $w -> field('id,picurl') -> select();
//
$arr = $wa -> field('id,logo') -> wherein('classid',array_column($data,'id'))-> select();
$res = array_column($arr , null, 'id');
foreach ($data as $key => $value)
{
$data[$key]['logoes'] = $res[$value['id']];
}
