In this paper we describe a query language called PFSQL (Priority Fuzzy Structured Query Language) that, beside basic fuzzy capabilities, adds the possibility to specify priorities for fuzzy statements. We give an analysis of possibilities to extend the SQL language and briefly describe the GPFCSP (Generalized Prioritized Fuzzy Constraint Satisfaction Problem) systems, a theoretical concept vital for the implementation of the PFSQL interpreter. In the following, we describe the most important ideas used in the process of the interpreter implementation. As one of the most innovative ideas we present the fuzzy JDBC (Java Database Connectivity) driver as a framework for the PFSQL interpreter.
