Purging Lobs

Purging LOBs : If we purge a table which contains LOBs , we may not reclaim space.  BLOBs are stored out of line once they exceed 4,000 bytes (you can also specify that they are always stored out of line as well). If the BLOBs were all inline, each taking 4000 or less bytes, then you did free space in your table.  The table will not shrink in size (tables NEVER shrink) but it will have more blocks on its free list for subsequent inserts.
