question about the lecture

Hi, I'm wondering that are these queries will change the database too, or it just output the result that we want?

No, a SELECT query in SQL is used only to read data from a database, not to change it. The purpose of a SELECT statement is to query the database for specific information; it fetches data from one or more tables but does not alter the data or the structure of the database.
