RE: On TRUNCATE table does the indexes also get truncated.
Title: RE: On TRUNCATE table does the indexes also get truncated. Hello, I deserved that the comments that were made, it is after all logical that they will be cleaned out. However in my defence, there are some funny thoughts that went through through my mind just before I truncated that table :-) Thanks anyway for them Regards Denham This e-mail message has been scanned for Viruses and Content and cleared by MailMarshal - For more information please visit www.marshalsoftware.com Note: This message is for the named person's use only.

Re: On TRUNCATE table does the indexes also get truncated.
Not having data in the indexes as some have noted,
is not answer the question of whether or not the
index was truncated.
Here's a simple test that will answer the question.
Feel free to use this methodology in the future. :)

Re: On TRUNCATE table does the indexes also get truncated.
It's elementary my dear Eva: if it didn't get truncated, then the index entries would be pointing to the non-existant rows. So, the answer to your question is: yup.
