      Returns the name of this factory.
      java.lang.String getIdentitySelectString​(java.lang.String tableName, java.lang.String columnName)
      Returns the database specific query string for retrieving last identity value.
      QueryExpression getQueryExpression()
      Returns a new empty query expression suitable for the underlying SQL engine.
      java.lang.String getSequenceBeforeSelectString​(java.lang.String seqName, java.lang.String tableName, int increment)
      Returns the database specific SELECT query string for fetching identity before the next INSERT statement gets executed.
      boolean isKeyGeneratorIdentitySupported()
      Does persistence factory support generation of unique keys with identity key generator?
      boolean isKeyGeneratorIdentityTypeSupported​(int type)
      Does identity key generator support generation of unique keys for the given SQL type?
      boolean isKeyGeneratorSequenceSupported​(boolean returning, boolean trigger)
      Does persistence factory support generation of new key at the time of new object creation with sequence key generator?
      boolean isKeyGeneratorSequenceTypeSupported​(int type)
      Does Sequence key generator support generation of key for the given SQL type?
      java.lang.String quoteName​(java.lang.String name)
      Returns the quoted identifier suitable for preventing conflicts between database identifiers and reserved keywords.
