We can attach an existing content database to a web application.

To attach an existing content database to a web application:

1.Restore a backup copy of the database in SQL.

2.Use the following PowerShell to attach an existing content database to a web application:

Mount-SPContentDatabase "<ContentDb>" -DatabaseServer "<DbServer>" -WebApplication http://SiteName

Refer to the article about attach or detach content databases in SharePoint 2013:
