在数据库开发和管理中，获取只有一个特定值的行是相当常见的任务。这听起来好像很简单，但是将结果限制在那些只具有一个值而又不包含其他值的行上，这比听起来要棘手。原因是，虽然使用 != 不等于或 NOT IN 比较运算符筛选值是很简单，但它们仅隐藏不匹配的值，而不是告诉我们实际是否拥有其他值。好消息是，有一种简单的方法可以做到这一点。请继续阅读，了解如何做到！
按角色选择用户
所有数据库以及大多数应用程序都有用户。特别是，数据库用户倾向于拥有不同的角色。（尽管应用程序用户也可以有角色。）以下是 Navicat 的表设计器中此类表的例子：
在这种情况下，role_id 是一个外键（FK），它链接到一个角色表，该表将存储有关每个角色的其他信息。在用户表中，包含 role_id 会导致每个用户有多行的可能性。请记住这一点，因为稍后我们会再次讨论这点。
列出只有一个角色的用户的错误方式
如果现在要列出拥有仅具一个特定用户角色的用户，我们可能要编写类似以下的查询：
问题在于上面的查询仅列出了 role_id 为 1 的用户。它并不能让我们知道他们是否也具有其他 role_id。此外，添加其他条件（例如 AND role_id NOT IN (2,3,4,5,6,7,8,9)）无济于事，因为 1 显然不是唯一的其他数字！
那么，如何将用户限制为只有 role_id 为 1 且没有其他角色的用户？
列出只有一个角色的用户的正确方法
从技术上讲，这不是“正确的方法”，因为肯定还有其他方法。该解决方案包括计算每个用户的行数。这个想法是，如果一个用户拥有我们感兴趣的 role_id 并且表中只有一行，那么他们就是我们想要在结果中看到的用户。
我们可以使用 GROUP BY 获得表中每个用户的 user_id 计数。然后，HAVING 子句可以检查用户是否只有一行，并且他或她的一个 role_id 是否我们想要的：
现在，我们只看到一个 role_id 为 1 的用户，而他没有其他 role_id！
总结
这种方法的优点是可以轻松地对修改查询，以查找表中包含多个值或超过特定行数的行。
