Business Objects Query Builder is a free application provided with Business Objects Enterprise XI (BOXI). It is uses the BOE SDK to provide a simple web user interface for submitting queries against the CMS InfoStore and returning their results.
Query Performance Concerns: Indexed Properties
As you begin to experience the wonders of Query Builder you will find that certain queries run quickly and other run very slowly, or not at all. It is important to remember that you are still querying a database and certain portions of that database have been indexed for improved performance in Business Objects. Among the lucky indexed properties you should find the following. For improved performance use these in your query’s selection criteria (WHERE clause):
Optimizing Query Builder Queries
Query performance is improved by using indexed properties in your selection criteria (WHERE clause); however, the order of these can additionally optimize your query’s performance. All selection criteria with indexed properties should be placed first in the WHERE clause. The BusinessObjects Enterprise CMS InfoStore, and therefore Query Builder, processes queries from top to bottom and left to right. Therefore the selection criteria should also be ordered from the most restrictive to the least restrictive. For example, SI_NAME = ‘My Report’ should be place before SI_KIND = ‘WebI’ in the query. It may not be the prettiest query but it will be the fastest.
si_name = '
si_kind = 'WebI' AND
si_instance = 0
