pub struct UpdateManyOperation<E: QueryEngine, M: Model> { /* private fields */ }

Update many records at once.

Implementations

impl<E: QueryEngine, M: Model> UpdateManyOperation<E, M>

pub fn new(engine: E) -> Self

Create a new UpdateMany operation.

pub fn where(self, filter: impl Into<Filter>) -> Self

Add a filter condition.

pub fn set( self, column: impl Into<String>, value: impl Into<FilterValue>, ) -> Self

Set a column to a new value.

pub fn set_op(self, column: impl Into<String>, op: WriteOp) -> Self

Apply a column-keyed WriteOp.

pub fn with_where_input<W: WhereInput<Model = M>>(self, w: W) -> Self

Apply a typed WhereInput. AND-composes with the existing filter.

pub fn with_update_input<I>(self, input: I) -> Self

where I: UpdateInput<Model = M, Data = UpdatePayload>,

Apply a typed UpdateInput.

See UpdateOperation::with_update_input for the lowering semantics — the only difference here is that update_many does not return rows.

pub fn build_sql(&self, dialect: &dyn SqlDialect) -> (String, Vec<FilterValue>)

Build the SQL query.

pub async fn exec(self) -> QueryResult<u64>

Execute the update and return the count of modified records.
