From: | | Victor Sokovin |
| Does Teradata create index for a derived table? if yes can we find the index column name/names and can we change it as per our requirement
for better performance ? | |
Derived table? It is an in-spool / in-memory object created by Teradata during query execution. It is internal and I don't think user can have
any control over it. If you want a better performance consider a different derived table. Experiment!
