# Output Query Result In Nicely Formatted Table
When I start a fresh SQLite connection and run a query, all the results are
squished together in a way that is poorly formatted, hard to read, and missing
column headers.
```sql
sqlite> select sessions.id, start_time, end_time, projects.name from sessions join projects on projects.id = sessions.project_id limit 3;

```
I can drastically improve the look of this by turning _headers_ on and switching
to _box_ mode.
```sql
sqlite> .headers on
sqlite> .mode box
sqlite> select sessions.id, start_time, end_time, projects.name from sessions join projects on projects.id = sessions.project_id limit 3;

I personally find that much easier on the eyes. It is also a nicer format to
copy and paste into a post like this or a formatted code block that I'm sharing
with a colleague.
I can also do this directly from the CLI with a one-liner using `-header` and
`-box` like so:
```bash
❯ sqlite3 /Users/lastword/.local/share/vmt/sessions.db -header -box "select sessions.id, start_time, end_time, projects.name from sessions join projects on projects.id = sessions.project_id limit 3"

Run the `.help` dot-command from a SQLite prompt for a full listing of these
commands. See also `sqlite3 --help` from the CLI for usage details about all
flags.
