About statistics for temporary table :
Is it best to have no statistics or Are they needed? Are they OK? Is there a problem if they have statistics? Any side effects.
I mean as such they do not have any rows so one would expect no statistics. If the data contained in them is known : then is it advisable to create a session : then populate the temp table and then gather statistics on them. Any issues with that. Or is it create a regular table with same structure then populate with representative data. Just trying to get the input on this and any exceptions/issues. Thanks
On one hand oracle says statistics on temp table is not supported but it also has note like :
Metalink note 403587.1 does talk about gathering statistics.
What about queue tables. Same questions for queue tables. ThanksReceived on Sun Dec 28 2008 - 11:02:51 CST
