> Key: DERBY-1062
> URL: https://issues.apache.org/jira/browse/DERBY-1062
> Project: Derby
> Issue Type: Improvement
> Components: Newcomer, SQL, Store
> Affects Versions: 10.1.3.1
> Reporter: Mike Matrigali
> Assignee: Mamta A. Satoor
> Priority: Minor

> Change the internal implemetation of SYSCS_INPLACE_COMPRESS_TABLE to share existing alter table
> code. One suggested approach is to use the same mechanism as SYSCS_COMPRESS_TABLE. Such
> an implementation would involve:
> o change the parser for alter table to accecpt some internal only syntax for SYSCS_INPLACE_COMPRESS_TABLE
> o change the alter table constant action to get the required information for inplace compress
> o move most of the inplace compress driving code to a routine in alter table execution, following the same
> coding pattern as existing alter table compress.
> I believe doing this will have multiple benefits:
> 1) shares existing alter table code, so things like error checking, security management, ... is all done by one piece of code
> 2) by sharing the code I believe the following outstanding JIRA issues will be addressed: DERBY-719, DERBY-720 -
> 3) future changes addressing ddl like grant/revoke will automatically work.
