So far, you’ve learned to use the SELECT statement to return data from tables. You also used the SELECT DISTINCT keywords together to return unique results. Finally, you learned how to use the COUNT() function to count the number of rows that match a specific query.

In this set of videos, you will learn about filtering to select subsets of data that match specific criteria. To accomplish this, you will combine the SELECT and WHERE statements, which are a fundamental part of SQL statements you will often use. Additionally, you will use the WHERE keyword to specify conditions on columns to return rows that contain particular data. For example, SELECT will specify the columns FROM a specific table, WHERE conditions are met.
