2. FETCH FIRST is only available since Oracle 12c. For the rownum approach, use a subquery that contains order by, then limit the rows in the enclosing query: SELECT * FROM (. SELECT * FROM ALARMS WHERE OBJECT_ID=0 AND TIMESTAMP<=152567750417. ORDER BY TIMESTAMP DESC.

This is where the concept of limiting results becomes crucial. Unlike some other SQL . If oracle supports row number (partition by) you can create a sub query selecting where row equals 1. SELECT * FROM table1. LEFT JOIN. (SELECT *. FROM (SELECT *, ROW_NUMBER() OVER(PARTITION BY assignmentgroup ORDER BY assignmentgroup) AS Seq. FROM table2) a. If so, replace "limit 3" with "FETCH FIRST 3 ROWS ONLY". If not, I think the standard Oracle-y thing to do is "SELECT * FROM (select id,somecol from sometable where someval=2 order by id desc) WHERE rownum <= 3" There are two ways to approach this: Have the client application run that query and fetch just the first N rows. Use that query as an inline view, and use ROWNUM to limit the results, as in SELECT * FROM ( your_query_here ) WHERE ROWNUM <= N. The second approach is by far superior to the first, for two reasons.
