Question

我使用此查询，但出现错误：

 $description = $request->get('description');
        if (!empty($description)){
        $description_query = Transcationhistorique::where(['sender_id' => $user_id, "%$description%", 'LIKE','description'])
            ->orWhere('receiver_id', $user_id)->get();
        }else{
            $description_query  =  "" ;
        }

这是我得到的错误：

“ SQLSTATE [42S22]：找不到列：1054'where中的未知列'0' 子句”（SQL：从transcation_historique中选择*，其中（sender_id = 32，0 =％salaire％，1 =相似，2 = 说明）或receiver_id = 32）“

这就是我真正想要运行的：

select * from `transcation_historique` where (`sender_id` = 32 and `description` = %salaire%) or `receiver_id` = 32)

Answer 1

尝试一下，

$description_query = Transcationhistorique::where(
                         function($query) use ($user_id, $description){
                             return $query->where('sender_id', $user_id)
                                          ->where('description', 'like', '%' . $description .'%');

                         }
                     )
                     ->orWhere('receiver_id', $user_id)
                     ->get();

Answer 2

似乎您的where查询结构不正确。如果要使用除“ =”之外的其他运算符，则应使用以下结构 Source

    [DllImport("NativeCore.dll", CallingConvention = CallingConvention.Cdecl)]
    [return: MarshalAs(UnmanagedType.LPWStr)]
    public static extern string GetNodeName(IntPtr ptr);

}

我的建议是：

[DllImport( "my.dll", CallingConvention = CallingConvention.Cdecl, CharSet = CharSet.Unicode )]
private static extern void GetMyString(StringBuffer str, int len);
public string GetMyStringMarshal()
{
    StringBuffer buffer = new StringBuffer(255);
    GetMyString(buffer, buffer.Capacity);
    return buffer.ToString();
}

Answer 3

尝试这个：

Transcationhistorique::where('receiver_id', '=', $user_id)
        ->orWhere(function ($query) use ($user_id, $description) {
            $query->where('sender_id', '=', $user_id)->where('description', 'LIKE', "%".$description."%");
        })->get();

Answer 4

您可以将多个where方法用作and。您可以尝试遵循以下代码吗？

    $description = $request->get('description');
    if (!empty($description)){
        $description_query = Transcationhistorique::where('sender_id', $user_id)
        ->where("description", 'LIKE','%' . $description . '%')
        ->orWhere('receiver_id', $user_id)->get();
    }else{
        $description_query  =  "" ;
    }
