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
