thank you for your answer. But actually i want to find average of values in each column and then i want to store average values in rows. how to do it?
something like
col1 col2 col3
3 4 5
5 5 6

average of col1 is 4
average of col2 is 4.5
average of col3 is 5.5

now i want the average values to be stored in rows
avg1 4
avg2 4.5
avg3 5.5
