Shashi,

Pick a forum.

Stick with it.

Asking variations of the same question in a zillion different forums (without reference to each other) is just confusing and frustrating (for both youand us).

Carefully read and then re-read all the responses provided to you in all the forums in which the question has been asked. If, after that, you are still confused pick the forum in which you feel the question has been most adequately addressed, and restate the nature of your confusion there.

Then close this thread in all the other forums in which it has been opened,and instead politely direct contributors to the one remaining 'open' thread.

Hi, this may sound ridiculuos but i want to know how can i insert a
polygon into database, if i only know the radius of the polygon.

Like i have a polygon, centered at the origin, with radius, say 5. Now
how can i insert it into mysql database? I hope we need to know the
vertices of it before inserting.

How can this be achieved?
Are you trying to use the MySQL spatial extensions, or is this just
a general geometry question?

The spatial extensions sort of work, but all they really can look
up efficiently is point-in-rectangle.
