Mamta A. Satoor updated DERBY-5138: ----------------------------------- Labels: derby_triage10_10 features (was: features) > Why can not create session indexes, session unique indexes and identity > columns in temporary session tables > ----------------------------------------------------------------------------------------------------------- > > Key: DERBY-5138 > URL: https://issues.apache.org/jira/browse/DERBY-5138 > Project: Derby > Issue Type: Improvement > Components: SQL > Affects Versions: 10.7.1.1 > Environment: windows, linux > Reporter: Oscar Bonilla > Labels: derby_triage10_10, features > Attachments: DB2 script.txt > > > I am a senior programmer in sybase (transact sql) and Oracle. I had to > convert a lot of programs to work in DB2. There are many processes that > require a lot of rows in temporary tables that needs join together, and they > expends much time to execute without indexes. I have to transform the logic > to do that with permanent tables with indexes those I have to drop after the > process. Now, DB2 can do "create unique index SESSION.xx_I01 on SESSION xx" > and this resolve my problem with the efficienty of the processes. In another > hand, I do not have any problem to use "GENERATED ALWAYS AS IDENTITY" in a > temporary session table in DB2. With this 2 issues it is imposible to > migrate all the systems to work with Derby. Thank. -- This message is automatically generated by JIRA.
