Applies to:

Oracle Database - Enterprise Edition - Version 8.1.5.0 to 11.1.0.6 [Release 8.1.5 to 11.1]
Information in this document applies to any platform.

Symptoms

When SQL statements use analytic functions ROW_NUMBER, FIRST_VALUE or LAST_VALUE it is sometimes possible that inconsistent results are produced.
The same SQL executed repeatedly on the same unchanging table data can produce different results.
This can be mistaken for an intermittent wrong results bug when in fact it could be a SQL coding issue.

Changes

This type of problem can occur when coding new SQL statements using the above analytic functions.
