公司DBA支持给建议不要用sysindexkeys来查找对应的列，而是使用syscolumns来提到：
比如：select * from syscolumns where id=object_id('dx.Article');
select * from sys.index_columns where object_id=object_id('dx.Article');

如何在Python中获取文件扩展名？
Sep 08, 2023 pm 01:53 PM
Python中的文件扩展名是附加在文件名末尾的后缀，用于表示文件的格式或类型。它通常由三个或四个字符组成，文件名后跟一个句点，例如“.txt”或“.py”。操作系统和程序利用文件扩展名来确定文件的类型以及应如何处理它。被识别为纯文本文件。Python中的文件扩展名在读取或写入文件时至关重要，因为它建立了文件格式以及读取和写入数据的最佳方法。例如，“.csv”文件扩展名是读取CSV文件时使用的扩展名，而csv模块则用于处理该文件。Python中获取文件扩展名的算法在Python中操作文件名字符串来
