DBQT IconDBQT - Database Query Tool
   © 2008 unu.ch

DBQT is a free Database Query Tool that has been developed for advanced users who want to analyze their databases with the help of SQL (Standard Query Language). It supports all common subsets of SQL such as DML (Data Manipulating Language) and DDL (Data Definition Language). With DBQT you can connect to nearly any kind of database system as for example: By default you can create a connection to any database which there is an OLE DB Provider installed for on your computer. Such an OLE DB connection will be created with the help of the “Data Link Properties” dialog that is an integral part of the Windows operating system. Moreover DBQT provides an interface that can be used to implement user-specific user controls for accessing any kind of database, on the only condition that there exists a managed .NET Framework data provider for it.

System Requirements

DBQT requires the Microsoft .NET Framework 2.0 to be installed on the target computer. If the .NET Framework is missing, DBQT will not be running. Furthermore, if you want to use the “Data Link Properties” dialog to create database connections, there is also required the Microsoft Data Access Components (MDAC). You can download either one or both of these two components from the following URL's.
