Solution to error when using USER as database table name
1. Because User is a keyword, it can be solved by changing the table name.
2. If we do not want to change the table name, we cannot use User when operating this table, but should use [User], for example:
SELECT UserName FROM [User] WHERE UserId = 1
INSERT INTO [User](UserName,PassWord) VALUES('admin','admin').
