SQLite Command Line Interface Exit

When using the SQLite command line interface, there are several ways to execute SQL statements and exit the program. This article will explore these methods and provide examples of how to use them.

One way to execute an SQL statement against a database and then exit is by providing the path to the database file followed by the SQL statement in single quotes. For example:

```

sqlite3 mydata.db 'select * from memos where priority > 20'

```

This will execute the SQL statement and display the results.

Another way to use SQLite is to open an interactive shell against an existing database. To do this, provide the path to the database file when starting the SQLite command line interface:

```

sqlite3 mydata.db

```

Once in the interactive shell, you can execute SQL statements and view the results.

You can also start an interactive shell with a new database by simply running the SQLite command line interface without providing a database file:

```

sqlite3

```

This will create a new database file named `sqlite.db` and open it in the interactive shell.

It's worth noting that multiple SQL statements can be separated by semi-colons. For example:

```

sqlite3 mydata.db 'insert into memos values('lunch with Christine', 100); insert into memos values('deliver project description', 10)'

```

This will execute both SQL statements and exit the program.

Additionally, SQLite allows you to attach to multiple databases within the same interactive session using the `ATTACH` command. For example:

```

sqlite3 mydata.db 'ATTACH 'path/to/other/db.sqlite3' AS other_db'

```

This will allow you to execute SQL statements against both databases.

In summary, the SQLite command line interface provides several ways to execute SQL statements and exit the program. Whether you need to execute a single statement or open an interactive shell, SQLite has got you covered.
