Recap and Feedback

In this part, you learned the first practical SQL tools for working with a single table. You used SELECT, WHERE, NULL, sorting, limiting, expressions, and the basic data-modification statements INSERT, UPDATE, and DELETE.

At this point, you should be more comfortable reading a table, writing a query for it, and checking what a change statement actually does before trusting the result.

You also continued the study tracker project. First, you practiced direct SQL against the project database, and then you added one small read-only feature that used the same database from application code.
