s用于共享！！：-）而且，我不知道布拉格语；谢谢你的例子和链接+1.这不会显示使用ALTER语句添加的列。您的意思是：

where t.name='table'sqlite3

（或任何为您命名的语言）进入sqlite CLI，然后键入该文本。不需要为此编写大量代码：）是的，正如@Xerus所说。。。不需要大量的代码。直接使用sqlite3即可。此外，@birdbuster还有助于指定您正在使用的语言和库。它看起来像C++（来自<代码> SpRtff函数）。这有助于澄清，因为OP问题是语言不可知的。哇！！！我不知道

.mode列

。这是一个多么强大的工具，可以快速地以交互方式可视化和调试数据！谢谢！！：-）+1.这是非常有帮助的，我想这最终会被接受的！
