Mysql 执行查询需要花费多少时间？
我试图在一个模板中获取所有用户，但是下面的函数和查询要花很长时间才能加载！如何优化下面的函数和查询？如果用户在$search_params参数中超过6k，则该查询几乎需要1分钟来加载用户 假设搜索参数为： 查询：Mysql 执行查询需要花费多少时间？,mysql,sql,symfony1,symfony-1.2,Mysql,Sql,Symfony1,Symfony 1.2,我试图在一个模板中获取所有用户，但是下面的函数和查询要花很长时间才能加载！如何优化下面的函数和查询？如果用户在$search_params参数中超过6k，则该查询几乎需要1分钟来加载用户 假设搜索参数为： 查询： public static function getBtqUsers($search_params) { $criteria = new Criteria(); $criteria->clearSelectColumns(); $criteria->

谢谢，因为您有很多连接，而且很可能没有索引的字段上有更多的条件，所以查询可能需要一些时间。如果你有很多数据，1分钟对我来说很正常 您可以尝试添加一个可以调用
user\u indexuser\u索引。如果您的user\u索引始终准确不是必需的，那么您还可以创建一个cron作业，该作业每隔5分钟更新user\u索引。使用此方法，您的查询速度会快得多，但如果您在每次更改源表时更新user\u索引
，则保存操作会慢一些
还要检查您的条件中的字段是否已正确索引，user\u index
表中的相同帐户。可能是需要优化的数据库，以便更好地执行此查询时间。为数据库提供足够的RAM，正确配置数据库，创建一些缺少的索引是您可以执行的一些任务。即使有这么多的连接，10秒的执行时间已经太多了！
