FETCHGRAPH

public static final String FETCHGRAPH

Hint providing a "fetchgraph" EntityGraph. Attributes explicitly specified as AttributeNodes are treated as FetchType.EAGER (via join fetch or subsequent select). Note: Currently, attributes that are not specified are treated as FetchType.LAZY or FetchType.EAGER depending on the attribute's definition in metadata, rather than forcing FetchType.LAZY.

FOLLOW_ON_LOCKING

public static final String FOLLOW_ON_LOCKING

Hint to enable/disable the follow-on-locking mechanism provided by Dialect.useFollowOnLocking(QueryParameters). A value of true enables follow-on-locking, whereas a value of false disables it. If the value is null, the the Dialect strategy is going to be used instead.

5.2

PASS_DISTINCT_THROUGH

public static final String PASS_DISTINCT_THROUGH

Hint to enable/disable the pass-distinct-through mechanism. A value of true enables pass-distinct-through, whereas a value of false disables it. When the pass-distinct-through is disabled, the HQL and JPQL distinct clause is no longer passed to the SQL statement.
