Subqueries in HAVING in Lite?

Question

I am a student of SQL. My professor can run this on his full
blown ORACLE server using but this will not run under lite.
I looked in the doc and did not see this restriction under the
Comparison topic. The problem appears to revolve around the
subquery in the having
Select itemno count(*) from lineitem
group by itemno
having count(*) = (Select Count(*) from sale);
I get a "not a single-group GROUP BY
function message". It works fine if I put in a number (having
count(*) = 5). Am I doing something wrong or this a difference
between Lite and full ORACLE??
Thanks Dave Blazosky
Tables look like
SQL> DESCRIBE sale
Name Null? Type
SALENO NOT NULL NUMBER(10)
SALEDATE DATE
SALETEXT CHAR(50)
SQL> DESCRIBE LINEITEM
Name Null? Type
LINENO NOT NULL NUMBER(10)
LINEQTY NUMBER(10)
LINEPRICE NUMBER(7,2)
SALENO NOT NULL NUMBER(10)
ITEMNO NOT NULL NUMBER(10)
null

: Dave,
: Place a comma(,) after the itemno in the SELECT statement and
re-
: run it.

A typo when I entered into this message box. Reran and still the
same problem. Good spot though. I cut and pasted from lite below
SQL> Select Count(*) from sale;
COUNT(*)
5
SQL> Select itemno, count(*) from lineitem
2 group by itemno
3 Having count(*) = 5;
ITEMNO COUNT(*)
2 5
SQL> Select itemno, count(*) from lineitem
2 group by itemno
3 Having count(*) = (Select Count(*) from sale);
Select itemno, count(*) from lineitem
