<p>I have an mysql procedure that returns a function of two values. The result is based on database tables.</p>
<p>I am calling it from birt as a data set like this:</p>
<p>Query text: {call getGxPercentile(?,?) }</p>
<p> </p>
<p>That works fine with the default values but I want to use that function dynamically at the end of each group.</p>
<p>The two arguments will be two aggregations of the group.</p>
<p>And I would like the result to be in a table group footer row.</p>
<p> </p>
<p>Would anyone know how to do that? Basically the procedure call needs to be done at the end of each group and the result placed in the footer row.</p>
