How to write SQL statement of hotel management

Your description of the problem is not clear and accurate enough. Sql statement is a method to add, delete and modify queries in the database. Database is a tool for storing data and a software server. Therefore, sql statement is not directly related to hotel management. The only possible relationship is that hotel management is a system, and the data in this system is stored in a database. Then we need to use some needed data. We should filter in the database through sql statement, and then get the hotel management we want through sql statement.
