How do I do top 1 in Oracle?
If you want just a first selected row, you can:
select fname from MyTbl where rownum = 1
You can also use analytic functions to order and take the top x:
select max(fname) over (rank() order by some_factor) from MyTbl
With Oracle 12c (June 2013), you are able to use it like the following.
SELECT * FROM MYTABLE
--ORDER BY COLUMNNAME -OPTIONAL
OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY
SELECT *
FROM (SELECT * FROM MyTbl ORDER BY Fname )
WHERE ROWNUM = 1;
