Look for a folder named "extras" in the download file. This folder contains two database scripts, one for Microsoft SQL and one for MySQL or MariaDB.
The scripts do not include a statement to name the database or to drop existing tables. So you need to create a New Database named "banner", and then run the script for that database.
The two files are named appropriately. Run the appropriate file as a "query" to build your database. (No additional help is provided in this help document.)
Be sure to check the connection string, change the target database and password to match your own situation.
