我正在使用 laravel eloquent 從多個列中獲取數據。我正在使用數組從多個列中獲取數據。為簡單起見，我顯示了兩列的數據。這是我的數據庫表，其中包含callee_number和caller_number：這是我使用數組來獲取列的代碼： $paramArray = $params->all(); $Caller_number = ""; $Callee_number = ""; if (isset($paramArray['Caller_number']) && $paramArray['Caller_number'] != '') { $Caller_number = $params->input('Caller_number'); } if (isset($paramArray['Callee_number']) && $paramArray['Callee_number'] != '') { $Callee_number = $params->input('Callee_number'); } if($Caller_number!=null){ $querypart[] = "caller_number=$Caller_number"; } if($Callee_number!=null){ $querypart[] = "callee_number=$Callee_number"; } $FinalQueryPart = ''; if (!empty($querypart)) { $Seprator = ""; foreach ($querypart as $querypartValue) { $FinalQueryPart .= $Seprator . $querypartValue; $Seprator = " AND "; } } $FinalQueryPart = trim($FinalQueryPart); //Output: "caller_number=783 AND callee_number=77" 但是，在上面的代碼之后運行以下代碼后，我收到錯誤： $gets = Tbcdrnew::where(function ($query) use ($FinalQueryPart) { $query->MIN('uniqueid')->where($FinalQueryPart) ->from('cdrnew'); })->groupBy('uniqueid')->orderBy('Start_Date','DESC')->get();錯誤如下：Illuminate\Database\QueryException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'caller_number=783 AND callee_number=77' in 'where clause' (SQL: select * from `cdrnew` where (`caller_number=783 AND callee_number=77` is null) group by `uniqueid`不明白我的代碼中有什么問題。有人可以糾正我嗎？

我認為您在查詢中犯了一個錯誤。將以下行替換為這些行：
if($Caller_number!=null){
$querypart[] = "caller_number = '$Caller_number'";
}
if($Callee_number!=null){
$querypart[] = "callee_number = '$Callee_number'";
}
$Caller_number（請注意&上的單引號$Callee_number）。
另外，使用該whereRaw()方法而不是where()按照響應評論中建議的方法。

我添加了一個答案，建議一種通過使用 Laravel 集合方法消除所有條件來簡化代碼的方法if。
$query = Tbcdrnew::query(); //start a query string based on Tbcdrnew model OR you could do DB::table('cdrnew');
collect($paramArray)->filter(function($value, $key){ //convert paramArray into a collection
return $value != ''; //filter all null and empty values
})->each(function($value, $key) use ($query){ //iterate through all filtered values
$query->where(strtolower($key), $value); //assuming array key is always column key in lowercase
});
$result = $query->groupBy('uniqueid')->orderBy('start_date','desc')->get();
我不確定$query->MIN您的原始查詢中是否有有效的查詢生成器函數。
