If you want the number of rows returned by the first query:

SQL

select count(*) from (select COUNT(flag)as rows from mytable where mycolomn0= 'N'  group by mycolomn1) as t

If you want the total number of rows returned :

SQL

select sum(rows) from (select COUNT(flag)as rows from mytable where mycolomn0= 'N'  group by mycolomn1) as t

Solution 2

Try this, you will get total count

SQL

select COUNT(flag)as rows from mytable where mycolomn0= 'N'

Why you need this

SQL

'group by mycolomn1

Thanks

What about:

SQL

SELECT 
  COUNT(*)
FROM
  (select COUNT(flag) from mytable where mycolomn0= 'N'  group by mycolomn1)

Solution 4

? i guess you just need to remove the group by statement to count the returned rows.

SQL

select COUNT(flag)as rows from mytable where mycolomn0= 'N'
