mysql - Eloquent - 自己连接表

Question

我正在尝试自己连接一个表，但总是出错。这是我当前的代码。我也尝试过 Raw 语句。目前不确定该往哪个方向走。

我的代码:

$Calle = db('VoipBill')
                    ->table('billing')
                    ->join('billing', 'billing.srcnum', '=', 'billing.dstnum')
                    ->where('acct_name', '100080_company')
                    ->where('srcnum', $call->srcnum)
                    ->whereBetween('calldate', [$set_time_lower, $set_time_upper])
                    ->get();

这是错误:

SQLSTATE[42000]: Syntax error or access violation: 1066 Not unique table/alias: 'billing' (SQL: select * from billing inner join billing on billing.srcnum = billing.dstnum where acct_name = 100080_company and srcnum = +27******** and calldate between 2016-05-02 09:19:27 and 2016-05-02 09:19:37)

您必须为表设置别名。以这种方式尝试:

    $Calle = db('VoipBill')
        ->table('billing as bsrc')
        ->join('billing as bdst', 'bsrc.srcnum', '=', 'bdst.dstnum')
        ->where('bsrc.acct_name', '100080_company')
        ->where('bsrc.srcnum', $call->srcnum)
        ->whereBetween('bsrc.calldate', [$set_time_lower, $set_time_upper])
        ->get();
