RE: Re-claiming the space from Table after deleteion

[Johan [EMAIL PROTECTED] Services]

TRUNCATE the table by using:

TRUNCATE TABLE <table_name>;

Just remember that this command falls under ddl, ie.
- An implicit commit is fired (no rolling back)

Everything is deleted, and the high water mark reset

Cheers

 If we delete data from a table, tables highwater mark doesnot come down.
That's why u cannot reclaim the freespace after deletion from a table.
