About This Item

 

Full Description

This document discusses the syntax and semantics for recognizing patterns in rows of a table, as defined in ISO/IEC 9075-2, commonly called °°°SQL/RPR°°°.
SQL/RPR defines two features regarding row pattern recognition:
°°° Feature R010, °°°Row pattern recognition: FROM clause°°°
°°° Feature R020, °°°Row pattern recognition: WINDOW clause°°°
These two features have considerable syntax and semantics in common, the principle difference being whether the syntax is placed in the FROM clause or in the WINDOW clause.
