I have a visualization in CartoDB of a set of data points in table
pointlayer. I am using cartodb.js and have a nice map for browser consumption.
When a user clicks on a point, I'd like to run a sql query that returns multiple rows relating to the clicked-upon point, and I'd like to put all that into the infowindow.
select column_a column_b, etc from anothertable join pointlayer on pointlayer.point_id = anothertable.point_id where pointlayer.point_id = <cartodb_id of clicked on point>
anothertable may have 0 or more rows for any
Is this possible with infowindows? Looks to me like the answer is probably no: they are designed for a single row. I suspect that I need to find a solution other than using CartoDB's infowindow (e.g. using Leaflet's popup), but I thought I would ask.
An answer here on stackexchange suggests to "actually query the table and get back all data." It doesn't state that the infowindow itself can be used to display it...though I could be reading it incorrectly.
