这里的一点是，你可以使用左连接而不是内连接，我认为这会更快。在HAVAING子句中填入where条件。另请注意，我正在应用IF条件，同时选择so，如果为null，则总和为0，否则为1。

请发布您的完整查询，而不是您想要的部分：）检查我的postrun解释并发布结果：

解释选择accomodation\u id，总和（accomodation\u rooms.rooms）作为房间总数，总和（住宿房间。床*住宿房间。房间）按accomodation_id作为accomodation_rooms组的总人数

你有关于accomodation_id和rooms的索引吗？嗯，如果我添加解释，说明：你的SQL语法有错误；检查与你的MySQL服务器版本对应的手册，了解使用“EXPLAIN SELECT accomodation_id，SUM（accomodation_rooms.rooms）”附近的正确语法至于“嗯，当我选择“计算”然后使用“拥有”时，它看起来真的更快。但我还有一个问题。我如何修改它以同时显示结果，它没有指定的纬度和经度，因此计算不可用？在我的选择中，有两个关于加入db_城市的条件-按ID或按距离你可以设置一个or条件having子句中。

having Calculation<20或Calculation为NULL

。我猜只有在计算不可用时才会出现NULL。ok它正在工作，但我没有注意到另一个问题…现在它只在id上连接表db_cities，但我还需要按距离范围连接城市…嗯，好的，但这并不快…问题仍然在INNE中R与SUM连用-我认为SUM是problem@general666查看我修改的第二个查询。尝试并告诉它是否更快。这个查询应该是什么？它是对原始问题的回答吗？简短的描述很好，可以让它对其他人有用。
