What is the most straightforward way to pad empty dates in sql results (on either mysql or perl end)?

Question

I\'m building a quick csv from a mysql table with a query like:

select DATE(date),count(date) from table group by DATE(date) order by date asc;

Answer 1

Use some Perl module to do date calculations, like recommended DateTime or Time::Piece (core from 5.10). Just increment date and print date and 0 until date will match current.
