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.

REGEXP_LIKE Negative Lookahead

Mar 16, 2021 12:16PM in SQL Language (MOSC) 5 commentsAnswered

Hi Everyone,

I have been researching about how I can do a negative lookahead with REGEXP_LIKE for more than one character/digit.

I would like to make the following work with REGEXP_LIKE. Can you please let me know if there is a way of doing the following with REGEXP_LIKE?

^(?!123([ -]?)45([ -]?)6789)(?!\b(\d)\3+\b)(?!000|666|900|999)[0-9]{3}([ -]?)(?!00)[0-9]{2}\4(?!0000)[0-9]{4}$

regex101: build, test, and debug regex

Thanks,

-Eb
