Abstract: The universal dynamic query can create query statement and command in the process of running program dynamically according to requirement. There are three implementation methods: utilizing user data dictionary, utilizing system tables, and utilizing the OLE DB data providers or services providers to implement the universal dynamic query. This paper studies the details of their principles and implementations, in additions, analyses and compares their advantages and disadvantages.
