Description
To improve how you show data to viewers, you can employ some advanced techniques by including queries within other queries. This also allows you to incorporate data from multiple data sources into a single table.
The following example on this page demonstrates a number of advanced techniques using this approach. It uses 2 inner SQL Query macros who's query depends on The example uses two inner SQL Query macros with queries that depends on the data provided by the outer query. Although not shown here, this technique can drive a query from another data source just as easily as from the same data source. Those queries can produce tables, as illustrated here, or a single value by using table=false in the wiki markup for the inner query.
