Struct BatchInsert

Source 
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.
Expand description

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
