Allow CREATE/REPLACE for users other than owner

Currently on Db2 LUW CREATE OR REPLACE is only allowed for the owner of a database object. CREATE OR REPLACE authorization should be opened up to allow create/replace by anyone who has the ability to drop the object and to create the object with a...

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

Allow modification of column-organized columns

Currently, in column-organized tables you cannot alter or rename columns and you even cannot drop columns. The only allowed operation is to add a column. This renders the column-based-tables pretty useless because in a normal environment, it must ...

Enhance ALTER STOGROUP DROP ‚storage-path’ with optional specification of the Path_ID

As you may ADD the same path multiple times to a storage group (in order to have multiple containers of a single tablespace within that path), it should be possible to even DROP a single reference to that path from the storage group as well! But s...

need to provide a RENAME SCHEMA statement (other database products provide this)

Need RENAME SCHEMA other databases other than DB2 LUW (i.e. MaxDB from SAP) provide a statement RENAME SCHEMA to rename a schema like a RENAME TABLESPACE/TABLE/INDEX. Needed on all supported operating systems.

Consideration of Statistical Views for INSERT with Sub-SELECT

Improve access plan resolution for SELECT MAX() (or MIN()) statements on range-partitioned tables with local (partitioned)

Context: range partitioned table with partitioned indexes A SELECT MAX() statement is issued on a field that is not the part of the partitioned key. The query is resolved by performing a full index scan on a partitioned index on that field. That i...

Add ALTER COLUMN options to modify numeric column length and allow rename column names for ((bi)temporal) column organized tables

Db2’s capabilities to perform schema changes on any form of ((bi)temporal) column organized tables lacks behind it’s row organized counterparts. This prevents effective database schema evolution and therefore limits the use of column organized tab...

Add support for INFORMATION_SCHEMA views

In our company we are using PostgreSQL, SQL Server, MySQL and DB2. All of database except Db2 support INFORMATION_SCHEMA views. There is pretty easy to write at least basic cross-database SQL to get info from database catalog tables except in Db2....
