I am showing content from product content type of commerce module using view but view is showing some repeated content.how to solve this problem.
Did you check How do I remove duplicates when using the random sort? before?
If it does not help you check views_distinct module
Relationships or other joins in Views often create "duplicate" results. For example, a node with a field that has multiple values may show up in the View once per value in the multi-value field. It's frustrating, and the "DISTINCT" SQL query option in the Views UI does not actually solve the problem because the result row is technically distinct. This module aims to give a simple GUI method to remove or aggregate these "duplicate" rows.
