Delete Unique Constraint in Oracle: Guide

To remove a unique constraint in an Oracle database, you can follow these steps:

First, log in to the Oracle database.

Use the ALTER TABLE statement to remove a unique constraint. For example, if you want to delete a unique constraint named “constraint_name,” you can execute the following statement:

ALTER TABLE table_name DROP CONSTRAINT constraint_name;

Please make sure to replace “table_name” in the above statement with the name of the table containing the unique constraint, and replace “constraint_name” with the name of the unique constraint to be removed.

After executing the aforementioned ALTER TABLE statement, the unique constraint will be removed.

Please be aware that removing the unique constraint may affect the data integrity in the database, please ensure you understand its potential impact before proceeding with this operation.
