## Cached query results

By default, when you run a report, JReport Engine fetches data from the database using the JDBC driver. For reports that are built on queries (and imported SQL files, stored procedures and UDSs which function as queries), JReport Designer enables you to create cached result files and save them somewhere in your machine. Then, when you view these reports, you can choose to use the data from the cached query result file as opposed to the database. This is very useful for working on the design of a report while you are off-line and do not have a DBMS connection. Additionally, it is helpful when you need to send data and reports to Jinfonet Support for assistance.

The following topics present how to create and use cached query result files:

- Creating a cached query result
- Using a cached query result to run a report
- Managing cached query results
