Laravel查询未正确绑定值

Question

我的查询返回错误的结果，我认为这是因为最终参数（分钟）没有绑定到查询。当我得到querylog一切似乎都很好，但错误的结果正在返回。如果我将minutes参数直接放入查询中，它会按预期返回正确的结果，但该值必须是变量。

要解释查询，它会计算所有记录，直到总分钟达到设定数字，在我的示例中使用500。

此查询可以正常工作并返回结果：

DB::select('SELECT NULL AS session_total_charges, NULL AS call_date, NULL AS inbound_duration, NULL AS total
  FROM dual
 WHERE @total := 0 
 UNION ALL
SELECT session_total_charges, call_date, inbound_duration,  @total := @total + inbound_duration AS total
 FROM (SELECT * FROM records  ORDER BY call_date) C where calling_user =:user and call_date LIKE :date AND outbound_zone_id IN ("UKX","UKM","UKLR","UKNR") and @total < 500', ["user"=>$user, "date"=>$date]);

此查询不起作用，只返回一行

DB::select('SELECT NULL AS session_total_charges, NULL AS call_date, NULL AS inbound_duration, NULL AS total
  FROM dual
 WHERE @total := 0 
 UNION ALL
SELECT session_total_charges, call_date, inbound_duration,  @total := @total + inbound_duration AS total
 FROM (SELECT * FROM records  ORDER BY call_date) C where calling_user =:user and call_date LIKE :date AND outbound_zone_id IN ("UKX","UKM","UKLR","UKNR") and @total < :minutes', ["user"=>$user, "date"=>$date, "minutes"=>$minutes]);


[query] => SELECT NULL AS session_total_charges, NULL AS call_date, NULL AS inbound_duration, NULL AS total


    FROM dual
     WHERE @total := 0 
    UNION ALL
    SELECT session_total_charges, call_date, inbound_duration,  @total := @total +  inbound_duration AS total
     FROM (SELECT * FROM records  ORDER BY call_date) C where calling_user =:user and call_date LIKE :date AND outbound_zone_id IN ("UKX","UKM","UKLR","UKNR") and @total < :minutes
