Abstract
This paper is mainly concerned with the extension of database management systems querying capabilities, so that users may address queries involving preferences and get discriminated answers. The use of flexible (gradual) predicates interpreted in the framework of the fuzzy set theory is advocated for defining a query language, called SQLf. SQLf enlarges the functionalities offered by SQL and the various roles of subqueries are presented from both semantic and query processing points of view
