Sql 这个查询错误？

错误为“上下文中指定的非布尔类型的表达式” 如果需要条件，则在“'）”附近。“

你的where没有任何意义。使用此

Where子句

这个子查询的意义是什么？您在父查询和子查询中选择的是同一个表，这完全没有意义。@mihai:不要格式化字段。它们与问题无关，通过将主要问题向下推几行来隐藏。这是哪种RDMB？根据我的经验，您的错误消息意味着您有语法错误。在这种情况下，当您使用WHERE子句时，您必须将某物与某物进行比较@NoDisplayName有正确的修复方法，但我想解释一下到底哪里出了问题。此外，在获得更多sql知识之前，不应该使用subqwUsers。它们很容易被误用，并在数据库中造成性能问题。在使用子查询之前，先学习使用WHERE子句、分组和连接的基本知识。
