我有一个在 SQL 服务器上完美运行的查询，但在 Oracle 中，我收到以下错误：

ORA-00923: 在预期的地方找不到 FROM 关键字

我已经尝试按照一些文章检查语法，但我无法解决它。在别名周围添加了“，尝试替换子查询中的属性名称不匹配父项，但没有任何效果。希望你能帮我解决这个问题，因为我已经到了我不知道接下来要尝试什么的地步！干杯

使用以下网站：https ://rextester.com/l/oracle_online_compiler 我尝试了您的 SQL 并得到了与您相同的错误。然后我开始将其简化为：

从 blah 中选择 1 作为 RowNum

并且仍然得到同样的错误。我认为 RowNum 是 Oracle 中的保留字，不能用作字段别名。
