我有一系列要查询的单词。我需要检查14个表中的每一列，以查看这些单词是否出现在Oracle数据库的任何表中的任何列中。然后，我需要在任何这些表中的任何列中选择包含任何这些单词的所有记录。有人可以为此提供高级方法吗？最初，我尝试通过创建外部循环来搜索列和内部循环来搜索每个列以查找要查询的单词。但是，我的直觉告诉Oracle有命令让我搜索所有表的所有列以查找我需要查询的单词列表。任何建议都会非常有用!!
谢谢！

希望现在你意识到这是一个非常糟糕的事情。我怀疑你正在使用的表可以使用一些规范化，并建议你可以考虑付出一点努力。正确完成后，关系数据库不仅仅是平面文件的集合。不知道任何细节，或多或少不可能提供更详细的建议。
祝你好运。
