Hello, I have a doubt I'm looking for for days, and I can't find a solution, neither in Google nor in forums.
I have a table that has connections with start time and end time, need to get the total number of links competitors namely, do a sweep searching for the final dates less than or equal to the initial dates of other connections.
Example a link starts the 10:00 and ends the 10:05, other link starts the 10:03 and ends the 10:10, are marked 2 competing links, due to they occupy the same space of time simultaneously.

How can I do???
Thank You Cesar Duarte
