Knut Anders Hatlen commented on DERBY-4289:
-------------------------------------------
Agreed. It may also make sense to mention the SYSCS_UPDATE_STATISTICS procedure
in case someone needs both in-place compression and update of statistics.
> Docs could be clearer on what SYSCS_UTIL.SYSCS_INPLACE_COMPRESS_TABLE does
> with statistics

> Key: DERBY-4289
> URL: https://issues.apache.org/jira/browse/DERBY-4289
> Project: Derby
> Issue Type: Improvement
> Components: Documentation
> Affects Versions: 10.5.1.1
> Environment: Solaris
> Reporter: Alan Burlison
> Priority: Minor
>
> The documentation for SYSCS_UTIL.SYSCS_INPLACE_COMPRESS_TABLE says:
> "Use the SYSCS_UTIL.SYSCS_INPLACE_COMPRESS_TABLE system procedure to reclaim
> unused, allocated space in a table and its indexes."
> The documentation for SYSCS_UTIL.SYSCS_COMPRESS_TABLE says in addition:
> "The SYSCS_UTIL.SYSCS_COMPRESS_TABLE system procedure updates statistics on
> all indexes as part of the index rebuilding process."
> I'm assuming SYSCS_UTIL.SYSCS_INPLACE_COMPRESS_TABLE also rebuilds the
> statistics, but the documentation doesn't day either way.
