Now that we know the database is empty, let’s create a new celebs table.
In the code editor, type:
CREATE TABLE celebs (
id INTEGER,
name TEXT,
age INTEGER
);
We will learn how to view this table in a later exercise after we have added some data to it.
The INSERT
statement inserts a new row into a table.
We can use the INSERT
statement when you want to add new records. The statement below enters a record for Justin Bieber
into the celebs table.
INSERT INTO
is a clause that adds the specified row or rows.
celebs is the table the row is added to.
(id, name, age)
is a parameter identifying the columns that data will be inserted into.
VALUES
is a clause that indicates the data being inserted.
(1, 'Justin Bieber', 22)
is a parameter identifying the values being inserted.
'Justin Bieber'
: text that will be added to name column
22
: an integer that will be added to age column.
Add three more celebrities to the table. Beneath your previous INSERT statement type:
INSERT INTO celebs (id, name, age)
VALUES (2, 'Beyonce Knowles', 33);
INSERT INTO celebs (id, name, age)
VALUES (3, 'Jeremy Lin', 26);
INSERT INTO celebs (id, name, age)
VALUES (4, 'Taylor Swift', 26);
Look at the Database Schema. How many rows are in the celebs table now?
<--There Are 4 rows-->
