这是我的基本查询:
$base_query = TableOne::join('table_two as p1', 'p1.order_id', '=', 'table_ones.id')
->join('table_threes as j1', 'p1.id', '=', 'j1.partner_order_id')
->select('table_ones.*')
->groupBy('table_ones.id', 'j1.status');
当有人需要筛选表2上的partner\u id之类的数据时,我们会添加这样的额外列,
$base_query->where(function ($query) {
$query->whereNull('p1.cancelled_at');
$query->orWhere('p1.cancelled_at', '=', DB::select(DB::raw("SELECT MAX(p2.cancelled_at) FROM partner_orders p2 WHERE p2.order_id = p1.order_id")));
$query->whereNotExists(function ($query) {
DB::select(DB::raw("SELECT * FROM partner_orders p3 WHERE p3.order_id = p1.order_id AND p3.cancelled_at IS NULL"));
});
});
但是在运行这个查询之后,他们的结果是一个错误
sqlstate[42s22]:找不到列:“where子句”中的1054未知列“p1.order\u id”(sql:select max(p2.cancelled\u at)from partner\u orders p2 where p2.order\u id=p1.order\u id)
我想,他们在这个问题上有些分歧。
$base_query->where(function ($query) {
$query->whereNull('p1.cancelled_at');
$query->orWhere('p1.cancelled_at', '=', DB::select(DB::raw("SELECT MAX(p2.cancelled_at) FROM partner_orders p2 WHERE p2.order_id = p1.order_id")));
$query->whereNotExists(function ($query) {
DB::select(DB::raw("SELECT * FROM partner_orders p3 WHERE
p3.order_id = p1.order_id AND p3.cancelled_at IS NULL"));
});
});

DB::select()
直接执行查询。如果是
orWhere()
,仅使用原始表达式。如果是
whereNotExists()
,使用whereRaw()
:在这两种情况下,还可以使用闭包并手动生成查询:
