Full support for aggregate function with DISTINCT in OLAP SPECIFICATION

Use of DISTINCT with e.g. COUNT function in OLAP specification (PARTITION BY clause) returns error SQL0441N (SQLCODE -441). Due to the fact that Db2 does NOT support the use of DISTINCT option in such cases, we have a major impact with COGNOS gene...

Fill gap with Oracle optimizer on RP tables

DB2 optimizer in v10.5/v11.1 has still several weaknesses in generating correct plan when using RP tables, because it bases its plan only on global stats when partition (data and indexes) stats are available. Case TS001150102

Optimizer does not use HIGH2KEY/LOW2KEY for columns with COLCARD 1

Optimization issue if a business_time_oriented table has only one row. In syscat.columns the content of the business_time columns are detected (high2key, low2key) but the value can not be found in the distribution statistics. This leads default fi...
