Completely updated for 2019, SQL Essential Training is designed to help users understand the most common language for database wrangling, SQL. All the lessons have been recorded in SQLiteStudio, an intuitive and easy-to-install database manager. Instructor Bill Weinman teaches all the major features of SQL: creating tables; defining relationships; manipulating strings, numbers, and dates; using triggers to automate actions; and using subselects and views.

So here we are using the test database again, and we're creating a table and dropping the table if exists, of course, and then inserting some rows into it. Let's take a look at this line here, now this is part of the create table statement. The create table statement is all of that, including everything in between the parenthesis. Between the parenthesis, we have the column definitions for each column. And the first column is named ID…
