Struct BatchInsert

pub struct BatchInsert<V, Tab, QId, const STABLE_QUERY_ID: bool> {
    pub values: V,
    /* private fields */
}

Available on crate feature i-implement-a-third-party-backend-and-opt-into-breaking-changes only.

This type represents a batch insert clause, which allows to insert multiple rows at once.

Custom backends can specialize the QueryFragment implementation via SqlDialect::BatchInsertSupport or provide fully custom ExecuteDsl and LoadQuery implementations

Fields

values: V

List of values that should be inserted

Can the SQL generated by Self be uniquely identified by its type?

type QueryId = QId

A type which uniquely represents Self in a SQL query.

fn query_id() -> Option<TypeId>

Returns the type id of Self::QueryId if Self::HAS_STATIC_QUERY_ID. Returns None otherwise.
