<font size=2 face="sans-serif">I have a resultset I stuff into the stash
for display. This works fine, but I am working on exporting the data to
Excel using Spreadsheet::WriteExcel. When I use $sr->result_source->columns
I get a list of the fields in the main table, but none of the columns from
related tables, and I get all the fields from that table even though I
am only calling for 4 with a "columns => [list of columns]".
Then when I try to iterate though the data with $sr->next(); the server
stops responding. I have scoured the docs and cannot find any help.</font>
