batchUpdate
abstract suspend fun batchUpdate(entities: Iterable<T>): DbResult<Long>(source)
Updates multiple entities in the data source using the specified driver context.
All the entities are written with a single UPDATE statement, each row matched by the entity's id (and version, for a versioned entity). The updated rows are not read back. The operation fails with SQLError.Code.RowMismatch (or SQLError.Code.OptimisticLockFailed for a versioned entity) when the number of affected rows differs from the number of entities. The rows that did match are already updated at that point: run it inside a transaction and roll back on failure for all-or-nothing semantics.
Return
A DbResult containing the number of updated rows (equal to the number of entities), or an error if the operation fails.
Parameters
The collection of entities of type T to be updated in the data source.
