How to get column count?

I would like to know which tickets are still open (those with Open=1 as last entry).  TicketNum is used to track added entries for a still open ticket.  TicketNum entries are just increments of the previous entry for the TicketTypeId.  Often, the same TicketType is used.  Once a ticket is closed and another open, the new ticket starts with TicketNum=1 and the process starts all over.

In the code example, only employeeIds 5 (Id=7) and 6 (Id=12) have open tickets.

 
Id   empId  ticketNum   TicketTypeId   Open   DateCreated
1       2           1     6              0
2       2           1     8              0
3       2           1     9              1
4       2           2     9              0
5       5           1     6              0
6       5           1     9              1
7       5           2     9              1
8       6           1     9              1
9       6           2     9              0
10      6           1     9              1
11      6           2     9              1
12      6           3     9              1

Select count(*) from table a inner join
(select max(Id), ticketNum as maxid from table group by ticketNum) b
on a.id = b.id and a.ticketNum = b.ticketNum
where a.Open = 1

Thanks but getting a few errors.

No column was specified for column 1 of 'b'

Invalid column name 'id'

Where you have a.id = b.id, b.id is not valid correct?
