Report Generator Demo

This is where you can play around with the hierarchical report generator by supplying a where clause in plain text and (de)selecting columns of the various lists (4 tables and a subselect) involved.

Behind The Scenes Explanation

This is where you get to see what's happening behind the scenes when you interact with the site on the left side.

The view consists of three (collapsible) parts...

1. Full Code, Queries, And Results

The server handles the web requests that are the result of you interacting with the site.
In doing so, the demo backend code is executed which in turn uses WYSE.

The relevant/notable methods taking part in that process are shown in the first vertical tab.
Basically you are seeing a (partial) stack trace.
It is tree structure of which the nodes are collapsible/expandable for your browsing convenience.

The leaves of the STACK TRACE TREE are where interaction with the database takes place.
That is generally where you will find the generated SQL statements and the JSON of the converted database results.

2. Queries And Results Only

A filtered list of entries where only the database queries and results are shown.

3. API Results

If applicable: this shows the JSON of the call to the server as if it had been an API call.
