适用范围:
Discusses the syntax and semantics for recognizing patterns in rows of a table, as defined in ISO/IEC 9075-2, commonly called 揝QL/RPR? SQL/RPR defines two features regarding row pattern recognition: - Feature R010, 揜ow pattern recognition: FROM clause? - Feature R020, 揜ow 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.
