QueryPage Method
Custom UIs can use the QueryPage method to query data in the Siebel database one page at a time. QueryPage supports both query-by-example (QBE) and predefined queries (PDQ). However, it is recommended that you use either QBE or a PDQ, but not both at the same time. If both QBE and PDQ are specified, then PDQ overrides QBE. In this case, the EAI UI Data Adapter executes the PDQ, ignores the QBE, and does not generate an error.
