MySQL页面上的查询的查询占用了我所有的时间，我想使用索引，但是我使用的是->这里有太多的地方，太多的特定东西对您有帮助吗?我不太确定如何优化它，因为加载页面需要花费很多时间

Cuz of the queries on MySQL page take forever to load I'm thinking to use indexing but I'm using ->Where too much here and too many specific things any help? I'm not really sure how to optimize it cuz it takes so many to load the page

推荐答案

好的！来吧.

首先，我强烈建议使用barryvdh/laravel-debugbar( GitHub ).这将准确告诉您触发了多少个查询以及每个查询花费了多少时间.

First of all, I highly recommend using barryvdh/laravel-debugbar (GitHub). This will tell you exactly how many queries were fired and how much time each one took.

现在，让我们谈谈优化.

• 尽可能使用select().如果一个表有20列且大约有1000行，而您要做的只是count()或sum()，则获取所有数据是没有意义的.
• 您的\App\Models\Drivers被多次使用.这是我的建议:
  • 查询1-> \App\Models\Drivers::where('is_approved', 1)->count();
  • 查询2-> \App\Models\Drivers::where('is_approved', 0)->count();
  • 解决方案-> $drivers = \App\Models\Drivers::whereIn('is_approved', [0, 1])->get();
    在这里您可以尝试 Laravel Collection
    $drivers->where('is_approved', 1)->count()
$drivers->where('is_approved', 0)->count()
    在查询运行两次之前，现在仅使用一次collect().
  • Use select() whenever possible. If a table has 20 columns and about 1000 rows and all your are doing is count() or sum() then fetching all the data doesn't make sense.
  • Your \App\Models\Drivers is being used multiple times. Here's what I recommend:
    • Query 1 -> \App\Models\Drivers::where('is_approved', 1)->count();
    • Query 2 -> \App\Models\Drivers::where('is_approved', 0)->count();
    • Solution -> $drivers = \App\Models\Drivers::whereIn('is_approved', [0, 1])->get();
      Here you can take adcantage of Laravel Collection
      $drivers->where('is_approved', 1)->count()
$drivers->where('is_approved', 0)->count()
      Before your query was running twice and now with collect() only once.

    希望这会有所帮助.干杯！

    Hope this helps. Cheers!
