Not entirely sure with what you're asking...

Do you want to select a word or value that occurs a specific number of times in a table?

Hi
What i'm asking is,
consider a database which contains so many tables like course, questionnaire,etc.

One of the table having a field about feedback_categories such as faculty effectiveness, course effectiveness, course structure, duration, etc.
For each of the course the feedback_categories may or may not differs.
Consider the feedback_categories fiels contains 100's of values that may or may not repeated.
Now how can i consolidate the feedback_categories, in the sense the values which occurs maximum numbers?
I have to write a php script that should consolidate dynamically all the common values.

I extract all the unique values in feedback_categories and fetch it in an array.
But I don't know how to match those values to find out which are the common values that occurs most of the time....

Please help me out........

Thanx n regards
