You can adjust the statement like this:
 select case when num = 1 AND email <> 1 then 'LogOKeMailnotOK'
              when num = 1 AND email = 1 then 'OK'
                      else 'LogFailed'
                      end as Result
        from (
      SELECT count(*) as Num,
                   max(IsEmailApproved) as email
        FROM Members
       WHERE MemberName = @UserName
         AND Password = HASHBYTES(@Algorithm, @Pass)
              ) AS X

OK then, change it to this:
 select case when num = 1 AND email <> 1 then 'LogOKeMailnotOK'
              when num = 1 AND email = 1 then 'OK'
                      else 'LogFailed'
                      end as Result
        from (
      SELECT count(*) as Num,
                   max(CASE When IsEmailApproved=1 THEN 1 ELSE 0 END) as email
        FROM Members
       WHERE MemberName = @UserName
         AND Password = HASHBYTES(@Algorithm, @Pass)
              ) AS X
