一、DB類查詢

DB::connection()->enableQueryLog();     //開啟執行日誌
$count = DB::table(‘test‘)              //執行查詢
->whereNull(‘deleted_at‘)
->where(‘id‘, ‘=‘, 3)
->where(‘Name‘, ‘=‘, ‘測試‘)
->count();
print_r(DB::getQueryLog());             //獲取查詢語句、參數和執行時間

返回值：

Array
(
    [0] => Array
        (
            [query] 
 
=> select count(*) as aggregate from `test` where `deleted_at` is null and `id` = ? and `Name` = ?
            [bindings] => Array
                (
                    [0] => 3
                    [1] => 測試
                )
            [time] => 1
        )
)

如果是ORM封裝的語句

$query = CdbForumSellthreadSearch::where($params
 
)->orderBy("$orderby", "$ascDesc")->offset($start)->limit($limit);
$list = CdbForumSellthreadSearch::where($params)->orderBy("$orderby", "$ascDesc")->offset($start)->limit($limit)->get()->toArray();

//打印出的sql是預編譯的sql語句，帶有問號占位符的sql 
print_r($query->toSql());
echo ‘<pre>‘;

//
 
下面打印出占位符對應的變量的值，數組裏面的順序和占位符的順序是一致的
print_r($query->getBindings()); 

laravel 獲取某個查詢的查詢SQL語句
