Abstract
The previous work studied such queries as simple query, compound query, multi-relational query, sub-query and etc, which solved fuzzy questions to some extent. But the logic conjunction was always AND or OR, Based on Zadehpsilas fuzzy theory, fuzzy logic conjunctions and weights are introduced here to extend fuzzy queries. This kind of fuzzy query will be solved here through combinations of fuzzy theory and SQL functions, which will improve fuzzy query system, thus enabling more effective queys.
