Define AWS database to use in Custom SQL?

Question

I am creating a dataset in AWS Quicksight using custom SQL which I prepare/test in Athena. However, unless I define each join/table "databasename".table, the QS custom SQL fails. I have tried the below but it has failed. Is it possible to instruct the query to fun against a specific DB at the beginning of the query?

```
USING AwsDataCatalog."databasename"
```

Answer

Thank you for posting the question and the detailed explanation on what you are expecting. 
At present, it is not possible to instruct a query to run against a specific database at the beginning of the query. I have raised a feature request with the service team on your behalf. While I am unable to comment on if/when this feature may get released, I request you to keep an eye on our [What's New](https://aws.amazon.com/new/?whats-new-content-all.sort-by=item.additionalFields.postDateTime&whats-new-content-all.sort-order=desc&awsf.whats-new-analytics=*all&awsf.whats-new-app-integration=*all&awsf.whats-new-arvr=*all&awsf.whats-new-blockchain=*all&awsf.whats-new-business-applications=*all&awsf.whats-new-cloud-financial-management=*all&awsf.whats-new-compute=*all&awsf.whats-new-containers=*all&awsf.whats-new-customer-enablement=*all&awsf.whats-new-customer%20engagement=*all&awsf.whats-new-database=*all&awsf.whats-new-developer-tools=*all&awsf.whats-new-end-user-computing=*all&awsf.whats-new-mobile=*all&awsf.whats-new-gametech=*all&awsf.whats-new-iot=*all&awsf.whats-new-machine-learning=*all&awsf.whats-new-management-governance=*all&awsf.whats-new-media-services=*all&awsf.whats-new-migration-transfer=*all&awsf.whats-new-networking-content-delivery=*all&awsf.whats-new-quantum-tech=*all&awsf.whats-new-robotics=*all&awsf.whats-new-satellite=*all&awsf.whats-new-security-id-compliance=*all&awsf.whats-new-serverless=*all&awsf.whats-new-storage=*all) and [Blog](https://aws.amazon.com/blogs/aws/) pages for any new feature announcements.
