Hi,
 I have a query like below

select count(*) from(
select examdate,patient_no from exams where requestedby=73201 and
examdate>='01/02/1988' and examdate<='05/01/1988'
and (height is not null or height!='') group by examdate,patient_no)

but when I execute I am getting the error which is shown below
Msg 102, Level 15, State 1, Line 4
Incorrect syntax near ')'.

Please let me know how can I do it.

Thank you

You need to name your derived table.  This syntax should work for you:

select count(*) from(
	select 
		examdate,
		patient_no 
	from exams 
	where requestedby=73201 
		and examdate>='01/02/1988' 
		and examdate<='05/01/1988' 
		and (height is not null or height!='') 
	group by examdate,patient_no) AS SourceQuery
