DB2 - Problembeschreibung

Problem IC84205 Status: Geschlossen

ADDING REDUNDANT JOINS TO FILTER ROWS OF AN OUTER JOIN OPERATOR MAY NOT
OCCUR DUE TO AN ERROR IN THE ANALYSIS

Produkt:
DB2 FOR LUW / DB2FORLUW / A10 - DB2
Problembeschreibung:
A problem in the algorithm of the analysis may result in not 
adding redundant joins to filter rows of an outer join operator. 
This problem may occur when there are at least two outer joins. 
 
Fixing this problem will improve the performance of the outer 
joins and potentially the overall performance of the query.
