Attention: To align with new corporate security policies, and to match policies adopted by other communities within Oracle, the My Oracle Support Community access requirements will change beginning September 18, 2025. MOSC will now require that member accounts in our community be associated to a *corporate* email address. This means that users with generic domains (such as gmail.com, yahoo.com, and others) will no longer be granted access to the discussion forums and ideas labs. If this policy affects you, act now to change the email address that is associated with your Oracle (and community) account. Alternatively, you can opt to create a new Oracle account that uses your corporate email domain.

Alternative to DISTINCT / GROUP BY

Sep 12, 2015 12:32AM edited Sep 26, 2015 6:13AM in SQL Language (MOSC) 3 commentsAnswered

Hi

I have a custom table comprising of 1 Million records, out of which the count of distinct combinations for 3 columns is 50 thousand.

When I'm trying to use either DISTINCT or GROUP BY to fetch these 50K records, query is taking around one hour.

Can you please suggest, what else can be done to improve query performance??

Thanks in advance,

Bharath
