SQLer turns natural-language questions into SQL for relational databases, giving developers a way to connect everyday wording with application queries.
What SQLer is
SQLer turns natural-language questions into SQL for relational databases, giving developers a way to connect everyday wording with application queries. It lists support for MS SQL, MySQL, PostgreSQL, and SQLite. Developers can supply company vocabulary, business rules, schema descriptions, and examples of questions paired with SQL to guide generation. Schema information can be set up through a direct connection, GATHERer, or uploaded SQL DDL files, and refreshed as schemas or metadata change. GATHERer runs as a Kubernetes container in the customer’s application environment and can transfer setup information with developer permission. SQLer generates SQL for the customer’s application to execute; its product page says results stay in the customer’s environment and lists single-tenant security. DaaX reports 96% equivalence to expert-written SQL on a customer benchmark of 300 production queries. The service is available on web and API platforms.
