Key: DERBY-2057
URL: http://issues.apache.org/jira/browse/DERBY-2057
Project: Derby
Issue Type: Bug
Components: Documentation, Javadoc, Store
Affects Versions: 10.2.1.6, 10.3.0.0
Environment: Any
Reporter: Yip Ng
There seems to be an error on the SYSCS_UTIL.SYSCS_INPLACE_COMPRESS_TABLE
documentation or the implementation itself when passing the following arguments:
PURGE_ROWS
If PURGE_ROWS is set to a *non-zero* value, then a single pass is made
through the table which will purge committed deleted rows from the table.
<snip>
DEFRAGMENT_ROWS
If DEFRAGMENT_ROWS is set to a *non-zero* value, then a single defragment
pass is made which will move existing rows from the end of the table towards
the front of the table.
<snip>
TRUNCATE_END
If TRUNCATE_END is set to a *non-zero* value, then all contiguous pages at
the end of the table will be returned to the operating system.
<snip>
The implementation only checks if the above arguments are 1s.
org.apache.derby.iapi.db.OnlineCompress.compressTable(
schema,
tablename,
(purgeRows == 1),
(defragementRows == 1),
(truncateEnd == 1));
