The Representation and Implementation ofFuzzy Query Based on Extended SQL
Fuzzy querg usually includes fuzzy words and three kinds of modifiers:linguistic, fuzzy as well as deterministic modifier.All these can be described with fuzzy set theory.To this end,this paper presents an approach for representing fuzzy query via Extended SQL(ESQL),which is then implemented by being transferred into standard SQL.
