How to select top 10 rows in oracle 11g

select top 10 foo , bar from yourtable order by foo desc. In this example, you will get the rows that have the highest ten foo values, because the ORDER BY sorts the rows into descending sequence, so the highest come first. If you want the bottom ten instead, don't code BOTTOM instead of TOP (because there's no such keyword as BOTTOM), just use. Oracle doesn't have a TOP keyword. Oracle also assigns ROWNUM before any ORDER BY, so your statement asks Oracle to get an arbitrary row from the student table and sorts it. You can do something like. SELECT *. FROM ( SELECT name FROM student ORDER BY grade) WHERE rownum = 1;. SQL Server has had TOP statement and combined with ROW_NUMBER() it was quite straightforward how to create a query that returns a range of rows â Oracle has not even had such TOP statement.

Before you begin, you should create a backup table in case you need to reference them after you have deleted records. Install 11g. Installation10gr2 Windows. In the two case, it instructs Oracle to optimize an individual SQL statement with a goal of best response time to return the first rows. For each row in this index, it probes the hash table to find the department ID. Top-N queries are queries that limit the result to a specific number of rows. To select the best execution plan, the optimizer has to know if the application will ultimately fetch all rows. In that case, a full table scan with explicit sort operation might perform best, although a pipelined order by could be.
