SELECT * FROM table1 LIMIT 10

 -- might give you what you're looking for.. I've not seen TOP, though I
could guess where it comes from (Oracle?) -- top seems to imply order so you
might want to ORDER BY something in the query before you LIMIT ...

See the LIMIT clause:

Hope this helps,

TOP is the MS Access equivelant to LIMIT

Text (cut down) from Access 97 help:-
Syntax
    SELECT [ALL | DISTINCT | DISTINCTROW | [TOP n [PERCENT]]]
    FROM table

TOP n [PERCENT]    Returns a certain number of records that fall at the top
of a range specified by an ORDER BY clause.  If you don't include the
ORDER BY clause, the query will return an arbitrary set of records.  The
TOP predicate doesn't choose between equal values.  You can also use the
PERCENT reserved word to return a certain percentage of records that
fall at the top of a range specified by an ORDER BY clause.


What this does not mention, although the syntax shows it, is that the
'predicates' (ALL | DISTINCT | DISTINCTROW | [TOP n [PERCENT]) must be
between the SELECT and the return list, and if more than one is used
must be in the specified order. (DISTINCT/DISTINCTROW before TOP)

However postgresql seems to requires LIMIT to be at the end of the
SELECT (only OFFSET after it). Also there is no PERCENT clause
available.
