Function diesel::update

pub fn update<T: UpdateTarget>(source: T) -> IncompleteUpdateStatement<T>

Creates an update statement. Helpers for updating a single row can be generated by #[changeset_for].

Examples

Updating a single record:

let updated_row = diesel::update(users.filter(id.eq(1)))
    .set(name.eq("James"))
    .get_result(&connection);
// On backends that support it, you can call `get_result` instead of `execute`
// to have `RETURNING *` automatically appended to the query. Alternatively, you
// can explicitly return an expression by using the `returning` method before
// getting the result.
assert_eq!(Ok((1, "James".to_string())), updated_row);
