Question

Say I have a table A and it has 5 columns (Column1, Column2.. Column5), the values in each column is one char size and stored only
as alphabetic as follows

    ID Column1 Column2 Column3 Column4 Column5
    1   A        C       D        A      B
    2   A        D       A        B      A
    3   B        K       Q        C      Q
    4   A        K       E        E      B
    5   F        K       F        F      S

I need a count of each different value stored in column1 to column5, I want the following information

     Column1 has A's count=3, B's count=1, F's count=1
     Column2 has C's count=1, D's count=1, K's count=3

     and so on

What is the correct way and format to return these values?

Thanks

You could try:

SELECT 'Col1' As 'Col', Column1 as 'Value', COUNT(*) as 'Ct'
FROM MyTable
GROUP BY Column1
UNION ALL
SELECT 'Col2', Column2, COUNT(*)
FROM MyTable
GROUP BY Column2
...

You will need to write an additional SELECT to UNION for each column you want to aggregate, but it will return the data you are after.
