Expand Up @@ -19,6 +19,25 @@ So far we have only looked at how to get information out of a database,
both because that is more frequent than adding information,
and because most other operations only make sense
once queries are understood.
Since our previous lesson exercise used the survey database with the same table names,
to continue with the next series of SQL statements, begin with the new database.
If you are currently within the SQLite interactive session, exit out.
~~~
.exit
~~~
Start the SQLite3 with a new empty database. Note the name is
different to avoid conflict with the existing survey database.
~~~
$ sqlite3 newsurvey.db
~~~
We can run the SQLite settings commands previously shown in Selecting Data exercise
to set the output mode to display left-aligned columns and turn on the display of column headers.
(Note if you exited and restarted SQLite3 your settings will change back to the default)
~~~
.mode column
.header on
~~~

If we want to create and modify data,
we need to know two other sets of commands.
