Handy Marker Browse SQL Joins Demo [V10.17.05.0159]

Previous Page
This application illustrates HandyMarkerBrowse in conjunction with three query control templates: HandyMarkerBrowseLocatorControlEx, HandyMarkerBrowseQueryBuilderControl and QueryParsingFilterControl.

This app was developed as a test application to study ABC Browse Class reset behaviour by tracing with HandySQLTrace. It was used in revisions to CHT Browse Classes and templates made May 2012.

The purpose of those revisions was to eliminate double and triple SQL requests send from the ABC Browse classes whenever the browse was reset by an order change or a filter change. The ABC BrowseClass function called ResetQueue() is a monument to inefficiency and bad design in the context of an SQL application.

Since CHT's HandyMarkerBrowse is an extension of the ABC browse class, all resets and queue refills are handled by the ABC Browse Class. Our efforts with this CHT browse extension revision was to as much as possible mitigate the inefficient behaviours built into the ABC Browse Class.

This application in conjunction with HNDSQLTRACE.EXE can be used to illustrate just how much CHT's latest Browse Extension templates can improve the speed and efficiency of your SQL browses.
