I wanted to edit the source code of Drizzle Database server so as so to incorporate these set-operations just as "union" is present. I know this set operations can be implemented using Drizzle sub- queries but most such queries are quite complex and using them by just a single command would greatly ease a lot of work. I want to take up this project under GSoC.

Take a look at drizzled/sql_union.cc for an example on how to do these.

Cheers,
