 Hope you had a good break. Let's continue with the session. In this second part of the session, we are going to start the discussion by discussing about another important keyword in SQL, `BETWEEN`.

+
+```sql
+SELECT * FROM products
+WHERE price BETWEEN 10 AND 50;
+```

We store it as `NULL`. Interestingly working with NULLs is a bit tricky. We cannot use the `=` operator to compare a column with `NULL`. Example:
