Structured Query Language (SQL) is used to obtain data from relational
databases. Fuzzy improvement of SQL queries has advantages in cases when the user
cannot unambiguously define selection criteria or when the user wants to examine data
that almost meet the given criteria. In this paper we examine a realisation of the fuzzy
querying concept. For this purposes the fuzzy generalized logical condition for the
WHERE part of the SQL is created. It allows users to create queries by linguistic terms.
The proposed model is an extension of the SQL so that no modification inside databases
has to be undertaken.
