：你能看看上面的编辑吗？我现在很迷茫。我目前正在阅读MySQL手册，运气不太好。我很想在我的查询中使用它。你不能仅仅用表列替换

，因为内部查询在我尝试时显然不知道外部表：@mellamokb:你是对的。将我的查询集成到Brandon的查询中会有点太麻烦（好吧，太麻烦了）。这就是为什么我给我的答案添加了一个存储函数。@ MelaMaMb:你在查询的中间留下了额外的分号，就在驻地细节之前。你的国王，解决了这个问题。我想在查询性能问题时保留这一点，并将PHP编码保持在最低限度。感谢大家的帮助。我相信我会有更多关于查询的问题。我在这里看到了很多潜力。你能看看上面的编辑吗？我现在很迷茫。我目前正在阅读MySQL手册，运气不太好。我很想在我的查询中使用它。你不能仅仅用表列替换
