Moved to the correct forum.

You will probably need to provide a few more details, since you are talking about a non-trivial activity.

A binary tree is a data storage object. It doesn't "fetch data", it "stores data". it sounds like you heard a buzz word and don't know what it is or when it is helpful. I would just use standard SQL and let the database handle storing your data. Also, a binary tree doesn't "show data". You need something else for that, like a table.

I believe most databases implement a b-tree structure.

actualy i'm working on multilevel marketing project. for that there are one root/admin and othes are affilates .so for that admin doesnt have more than one leg, leg must be right, left. and subordinate leg is also restricted to left and right. for that i want to show the subordinate name and id and generation of commision on complition of level. so i want to i that how should i fire the querry, and where ?

I suspect you are working on a homework assignment, as what you are saying makes no sense outside of that context. A properly designed database will handle all this for you. What are you ACTUALLY trying to accomplish? Without knowing the details you are constrained by, we can't guide you.

suggested me best possible way to do it. Simply using sql queries
without joins and functions is very tedious and time consuming . so
plz suggest me shortest possible script which takes less execution
time.

Do you know how this data will be stored in the database? You still need to read the data from the database into the tree.

Presumably you are storing your data in a database before you can fetch it into a binary tree. What format is it stored in? Also, how do you want it displayed? Sample data would be ideal.
