### Embed SQLite databases
If your application wants to embed a SQLite database, set `type: "sqlite"` in the import attribute and the `embed` attribute to `"true"`.
If your application wants to embed a SQLite database into the compiled executable, set `type: "sqlite"` in the import attribute and the `embed` attribute to `"true"`.
The database file must already exist on disk. Then, import it in your code:
```ts index.ts icon="/icons/typescript.svg"
import myEmbeddedDb from "./my.db" with { type: "sqlite", embed: "true" };

console.log(myEmbeddedDb.query("select * from users LIMIT 1").get());
```
This database is read-write, but all changes are lost when the executable exits (since it's stored in memory).
Finally, compile it into a standalone executable:
```bash terminal icon="terminal"
bun build --compile ./index.ts --outfile mycli
```
<Note>
The database file must exist on disk when you run `bun build --compile`. The `embed: "true"` attribute tells the
bundler to include the database contents inside the compiled executable. When running normally with `bun run`, the
database file is loaded from disk just like a regular SQLite import.

In the compiled executable, the embedded database is read-write, but all changes are lost when the executable exits (since it's stored in memory).
