Congratulations! You just learned how to query data from a database using SQL. What can we generalize so far?

  • SELECT is the clause you use every time you want to query information from a database.

  • WHERE is a popular command that lets you filter the results of the query based on conditions that you specify.

  • LIKE and BETWEEN are special operators that can be used in a WHERE clause

  • AND and OR are special operators that you can use with WHERE to filter the query on two or more conditions.

  • ORDER BY lets you sort the results of the query in either ascending or descending order.

  • LIMIT lets you specify the maximum number of rows that the query will return. This is especially important in large tables that have thousands or even millions of rows.
