i have a table that has millions of rows. just recently the query we run to look for errors is timing out, i need to run this query before sending the payroll data. Is there as way to reindex this table in hopes to speed this up, so the query can complete? I only have an hour so redesigning the tables now wont work.....

George,

If you simply want to do a fast re-index, then here is your code:

CODE

SQL> alter index s_emp_id_pk rebuild parallel;

Index altered.
Let us know if this takes care of business for you.

So, you've not told us the structure of the table, you've not told us what indexes you have on it, and you've not told us what query you're running on it. And you want us to tell you - within an hour - if it's possible to speed it up?

I'm gonna go with "Yes", because I'm a positive kinda guy, but it could be "No". I hope you find this helpful.

If you give us the select, we can probably suggest ways to speed up the query. Have you paid for the partition option?
