Re-executing query objects without affecting transaction data in an application development framework not providing for creation of multiple instances of the same query object

摘要

Re-executing query objects without affecting transaction data in an application development framework (ADF) not providing for creation of multiple instances of the same query object. In an embodiment, a query associated with a query object is executed to retrieve a transaction data from a data store, which can be further modified based on user interactions. In response to an indication that the query object is to be re-executed for retrieving the transaction data, a new query object is created using the query (along with any required parameters) retrieved from the original query object. The new query object is executed to retrieve a copy of the transaction data from the data store. According to another aspect, a comparison result is generated for the modified transaction data and the copy.
