许多人在编写程序的时候因为贪图方便或不小心使用到程式的保留字，有时明明程序没有错，就是无法正确执行。您知道有哪些常见的保留字吗?
下面的都是编程程序与表名都不能使用，如果不小心使用了，就需要下面的方法解决下
当用USER作为数据库表名时，出错的解决办法
1.因为User是关键字，所以更改表名即可解决。
2.如果不想更改表名，那么我们在操作此表时，不能用User，而应该用[User]，例如：
SELECT UserName FROM [User] WHERE UserId = 1
INSERT INTO [User](UserName,PassWord) VALUES('admin','admin')。
