I'm trying to enumerate keys in Amazon SimpleDB. In SQL, it would be something like:
select unique itemName() from domain;
I've searched around but didn't find any way to do this. Any help?

In contrast, Amazon SimpleDB is easy to use and provides the core functionality of a database - real-time lookup and simple querying of structured data - without the operational complexity. Amazon SimpleDB requires no schema, automatically indexes your data and provides a simple API for storage and access.
Amazon SimpleDB is a highly available NoSQL data store that offloads the work of database administration. Developers simply store and query data items via web services requests and Amazon SimpleDB does the rest.
Amazon SimpleDB provides simple index and query capabilities. Amazon RDS enables you to run a fully featured relational database while offloading database administration. And, using one of our many relational database AMIs on Amazon EC2 and Amazon EBS allows you to operate your own relational database in the cloud.
SimpleDB is deprecated, more expensive than DDB, and kind of weird to use. Backing your keystore with a deprecated service just sounds like a road to many sleepless nights ;) The utility does depend on three external services: DynamoDB, KMS, and IAM (for permissioning).
By definition, items in a domain are unique, so you were almost there:
select itemName() from domain
