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.

Removing duplicate string in a column

Jun 5, 2020 12:00PM edited Jun 5, 2020 2:15PM in SQL Language (MOSC) 6 commentsAnswered ✓

Hi,

A column contains duplicate email address stored in it.

String:

shyam@gmail.com,naresh@gmail.com,ram@gmail.com,shyam@gmail.com,naresh@gmail.com,shyam@gmail.com,kavita@gmail.com

In the above string, "shyam@gmail.com" is repeated thrice and "naresh@gmail.com" is repeated twice.

The data should be stored as - shyam@gmail.com,naresh@gmail.com,ram@gmail.com,kavita@gmail.com

In other words, there are no duplicate email address stored in the field.

Please let me know how do we achieve the same.

Thanks,

Krishna
