the create unique index statement terminated because a duplicate key was found for the object name

Question

Problem :

I am facing bellow error

the create unique index statement terminated because a duplicate key was found for the object name

Answer 1

The problem is not that index already exists but there are duplicate values of the TopicShortName field in the table itself. Such duplicates prevent the creation of a UNIQUE index.

So you should run a query to confirm that you have a duplicate:

SELECT
    TopicShortName,
    COUNT(*)
FROM
    DimMeasureTopic
GROUP BY
    TopicShortName
HAVING
    COUNT(*) > 1

Presumably in the other database the data are different, and the duplicates are not present.

This will certainly solve your problem.
