Subj:   Re: Delete in teradata
 
From:   Christopher J. Moore



Gemma,

The first thing that you want to do is drop all of the secondary indexes. You can then either do a multiload delete which should build a spool file of all the row hashes that will be deleted and then do a row hash match delete. Or you can insert the primary index values to be deleted into a temporary table (the 3 index columns only) and then do a delete via SQL matching the primary index keys. When finished recreate the secondary indexes. Hope this helps. What is your system configuration?
