    • setHint

      TypedQuery<X> setHint(String hintName, Object value)
      Set a query property or hint. The hints elements may be used to specify query properties and hints. Properties defined by this specification must be observed by the provider. Vendor-specific hints that are not recognized by a provider must be silently ignored. Portable applications should not rely on the standard timeout hint. Depending on the database in use and the locking mechanisms used by the provider, this hint may or may not be observed.
      Specified by:
      setHint in interface Query
      Parameters:
      hintName - name of property or hint
