SQL sublanguage: DQL (Data Query Language)

We have learned how to query all records from a table as well as filter the amount of records we get back utilizing the WHERE keyword.

In this lab we are going to learn how to filter the amount of columns that we want returned.

Let's take a look at the syntax to return an entire table again:

 SELECT * FROM table_name;

In the statement above, the * is the wildcard to retrieve all the columns in this specific table. However, we can specify the columns that we want to display by the following syntax:

 SELECT col_1, col_2, ...col_N FROM table_name;
