在没有全表扫描的情况下，复杂查询需要30秒

Question

我在32位机器上运行MySQL 5.1，我使用Hibernate标准来生成下面的查询；出于某种原因，我不能理解它需要30秒才能执行，即使根据“解释”所说的，没有执行全表扫描。

我们有一个完整的细节，股票，stocks_groups，指标，indicator_definition (加上其他不太相关的表，如国家，交易所...)。stocks表包含大约18000行，groups表包含大约3000行，indicators表包含超过710,000行。所有的表都使用自动生成的id列，并且我在indicators表中创建了一个额外的索引，该索引由(id，stock_id和definition_id)组成。如果我从查询中删除指示符，它将在0.030秒内执行，这是我所期望的，所以我猜一定有什么问题，但我对数据库的知识有点有限，我陷入了寻找解决方案的困境。

任何帮助都将不胜感激，

提前谢谢你，

哈比尔。

Answer 1

好吧，这是一个相当大的查询，然而，它将依赖于每个表上的索引，如果您将where子句移动到als1表上的连接，这应该会有所帮助，因为目前您正在创建所有连接的母亲，然后在最后说“哦，我只想要这一点”。

你能确认所有的id字段都有索引吗？

Answer 2

我只能假设每个表的“自增”列"ID“分别有一个索引。此外，我会确保Stock_Groups表在Group_ID上有索引...在virtual_groups_components上，virtual_group_id上的指标索引，stock_id上的指数

此外，由于您有如此多的连接组合，查询优化器可能会试图为您考虑太多应该首先使用哪个表，并得到一个糟糕的结果。我已经对表进行了排序，并将您的"Groups“表(别名1版本)移到了顶部，因为这是WHERE子句的基础。此外，我还添加了"STRAIGHT_JOIN“子句，它告诉编译器按照列出的确切顺序运行查询……因此，将首先查询"groups_als1_“版本，并应用where，获取您期望的最小记录集，然后连接到所有其他查找表以获得结果……显然，替换我的占位符"AllYourFields“。我会对结果感兴趣的。我以前已经用15+查找表对14+百万条记录进行了数据挖掘，并将查询从失败的30+小时减少到不到2小时(是的，检索和排序所有记录)。
