To avoid creating a DB connection from scratch, you can duplicate an existing one in the DB Connections list and work around its metadata to have a new connection.

## Before you begin

A database connection is created in the Profiling perspective.

## Procedure

1. In the DQ repository tree view, expand Metadata > DB Connections.
2. Right-click the connection you want to duplicate and select Duplicate from the contextual menu.

## Results

The duplicated database connection shows under the connection list in the DQ repository tree view as a copy of the original connection. You can now open the duplicated connection and modify its metadata as needed.
