Review and Practice0:57 with Andrew Chalkley
Let's review deleting rows in different ways and practice the different techniques.
You now know all CRUD operations, create, read, update, and delete, awesome.
To recap, to remove onrows from the table, you can write DELETE FROM <table>.
This removes every single entry in the table you specify.
To remove only the rows that match a particular condition,
you can use a where clause with any number of conditions.
Any rows matching the condition will be permanently removed.
Once again, to practice deleting rows
I've created a SQL playground with some more tasks for you to complete.
Familiarize yourself with the schema and the data and then complete the tasks.
You're finished with the main operations that CRUD has to offer, well done.
In our final section, we're going to look into handling multiple CRUD operations and
dealing with errors that you could encounter.
