]
Mike Matrigali updated DERBY-1964:
----------------------------------
Instead of:
The SYSCS_UTIL.SYSCS_COMPRESS_TABLE system procedure creates statistics for indexes if the
statistics do not already exist.
something like:
The SYSCS_UTIL.SYSCS_COMPRESS_TABLE system procedure will update statistics on all indexes
as
part of the index rebuilding process.
The reality is that we create a new statistic if no statistic existed, and we update existing
statistics with
current full information if they already existed. But I am not sure the documentation need
say that.
> Update the documentation of SYSCS_UTIL.SYSCS_COMPRESS_TABLE for the changes that went
in as part of DERBY-737

> As part of DERBY-737 "SYSCS_UTIL.SYSCS_COMPRESS_TABLE should create statistics if they
do not exist", SYSCS_UTIL.SYSCS_COMPRESS_TABLE now will create statistics for indexes if they
do not already exist. This needs to be documented. The changes went into 10.3 codeline when
I created this documentation jira entry. The changes may get ported to prior releases. Please
check DERBY-737 to see what all releases will need the documentation changes.
