In my query i want to take the distinct count

Table :

Coloumn 1     Coloumn 2   Coloumn 3
   1             Y           3
   2             Y           3
   3             Y           3
   4             Y           4
   5             Y           4

here i want the count of coloumn 2 and 3.
i tried

SQL

select count (distInct Coloumn 2 ),count (distinct Coloumn 3 ) from table.

but the result was count ( Coloumn 2 ) = 1 and count ( Coloumn 3 ) = 2
but am expecting count ( Coloumn 2 ) = 2 and count ( Coloumn 3 ) = 2
how can i do this?
Any solution ?

Your Question is still not clear, explain more about your Problem. For column 2 Distinct values is 1 right (Y). then how u will expect 2?

Column 3 values are different..here i need to take the count based on column 3.
since for column 3 for value 3 total 3 records and for value 4 total two records so the total count of column 3 should be 2 and column 2 should be 2.

How you are expecting the column 2 will get the count=2, because it has only one unique value. Your question is wrong.

Solution 1

I guess its not possible since distinct will only consider unique values. Since in column 2 only Y is present it will give the count as 1.

Solution 2

Use :

SQL

SELECT  count(T.Coloumn2 ) Column2Count, count(T.Coloumn3 ) Column3Count
FROM (SELECT DISTINCT Coloumn2 ,Coloumn3  FROM table) T
