## Ejemplo
|
|
|
|
```go
|
|
db, err := SQLiteOpen("/data/app.db")
|
|
if err != nil {
|
|
return err
|
|
}
|
|
defer DBClose(db)
|
|
```
|
|
|
|
## Notas
|
|
|
|
Retorna error si db es nil. En la mayoria de los casos se usa con `defer`. Existe como funcion del registry para que los pipelines puedan referenciarla en `uses_functions` y modelar el ciclo de vida completo de la conexion.
