In this paper, a new data query technique composed of fuzzy theory and MS-SQL is provided. Here, the query can be implemented for fuzzy linguistic variables query via an interface to Microsoft ASP.NET. It is being applied to an realistic instance i.e. questions could be expressed by fuzzy linguistic values such as young age, high blood pressure, average heart beat etc. in patients' relational database.
