It's actually "Cartesian Product", the result of a query like select * from
table1, table2; where you get all the virtual tuples (rows or relations)
that represent the set of each tuple in table1 coupled with each tuple in
table2. I good way to get all possible combinations of the records from
two tables, but is usually a runaway select error because you forgot to put
in a join between the two tables. Try the select above with two small
tables out of your database and look at the result.

Thanks for your response Per. Yes, the query is at my slow-log, I already
know that. I've made some changes and optimizations to my code to make it
faster. I was only curious what that status really mean.
Btw, what is "karthesian product"?
