Annotation Interface Jdbc.GeneratedKeys

Enclosing class:
Jdbc
@Target(METHOD) @Retention(CLASS) public static @interface Jdbc.GeneratedKeys
Requests generated keys from an update statement.

An empty value requests the generated keys selected by the JDBC driver. Otherwise, the provided values are passed to JDBC in declaration order.

Without a local transaction, the update may be committed before the repository finishes reading or mapping the generated keys, checking the expected number of keys, or releasing JDBC resources. Such a failure does not establish that the update was rolled back and must not be retried automatically. When key materialization and the update must be atomic, execute the repository method within a Helidon local transaction and allow the failure to escape the transaction boundary.
