brian , i have more than 200,00 records in my table

I will not be able to find each column value by getting the count of digits.

looking for one query which returns distinct count digits of my table record.

I think Brian has you on the right track although his select would return -
4
4
3
3
A distinct keyword would reduce that to -
4
3
However, you indicate the result should be 3,4 which might be accomplished using pivot.
