Class ResultSetConcurrency

  • public class ResultSetConcurrency
extends java.lang.Object
    JDBC ResultSet concurrency hint values. The class contains all the valid values for QueryHints.RESULT_SET_CONCURRENCY query hint. This can be used on ScrollableCursor queries to set the JDBC ResultSet concurrency. JPA Query Hint Usage:

    query.setHint(QueryHints.RESULT_SET_CONCURRENCY, ResultSetConcurrency.ForwardOnly);

    or

    @QueryHint(name=QueryHints.RESULT_SET_CONCURRENCY, value=ResultSetConcurrency.ForwardOnly)

    Hint values are case-insensitive. "" could be used instead of default value ResultSetConcurrency.Updatable.
