原始查询 CASE WHEN 在 Lumen 中不起作用？

Question

我想在 Lumen 中使用 CASE WHEN，但它 returns 消息“糟糕！发生错误。服务器返回了 500 内部服务器错误。”

//Working
$result = DB::table('Users')
    ->select(DB::raw('count(*) as user_count'))
    ->where('user_id', 'A1')        
    ->get();

// Working
$result = DB::select('SELECT CASE WHEN user_status="new" THEN "New"  ELSE "Expired" END AS new_status FROM Users WHERE user_id="A1"');

//Failed
$result = DB::table('Users')
    ->select(DB::raw('CASE WHEN user_status="new" THEN "New"  ELSE "Expired" END AS new_status'))
    ->where('user_id', 'A1')        
    ->get();

为什么失败了？

请试试这个：

//Try
$result = DB::table('Users')
    ->select(DB::raw('CASE WHEN user_status=''new'' THEN ''New''  ELSE ''Expired'' END AS new_status'))
    ->where('user_id', 'A1')        
    ->get();

//Try2
$result = DB::table('Users')
    ->select(DB::raw("(CASE WHEN (user_status='new') THEN 'New'  ELSE 'Expired' END) AS new_status"))
    ->where('user_id', 'A1')        
    ->get();
