Subj:   Re: Mload script to copy data from 1 table to another table in Teradata
From:   Fred W Pluebell

If you are going to use CREATE AS to copy a table, it's generally better to use the "AS existingTableName" syntax.

Whenever you use "AS (SELECT ...)" you should always include primary index specification at a minimum; even if the subquery is "SELECT *" from a single table, attributes of the underlying table(s) don't get copied when the data source is a query / spool file.
