Subject Re: [jira] Commented: (DERBY-720) Calling SYSCS_INPLACE_COMPRESS_TABLE on a synonym or a temp table results in a NullPointerException
Date Mon, 21 Nov 2005 17:56:25 GMT
Yes. When you create a temp. table, you can ask for the rows to be
PRESERVED or DELETED at the transaction boundary. Since temp. tables are
typically used for short duration (with in the same connection),
hopefully they can do without compressing... (in the short term)
