ABSTRACT
This demo showcases Scythe, a novel query-by-example system that can synthesize expressive SQL queries from input-output examples. Scythe is designed to help end-users program SQL and explore data simply using input-output examples. From a web-browser, users can obtain SQL queries with Scythe in an automated, interactive fashion: from a provided example, Scythe synthesizes SQL queries and resolves ambiguities via conversations with the users.
In this demo, we first show Scythe how end users can formulate queries using Scythe; we then switch to the perspective of an algorithm designer to show how Scythe can scale up to handle complex SQL features, like outer joins and subqueries.

Pulling Conjunctive Query Equivalence out of the Bag
CIKM '14: Proceedings of the 23rd ACM International Conference on Conference on Information and Knowledge ManagementWe present LECQTER, a tool for generating a 'perfect example' database, called exemplar, for a given conjunctive query. Indeed, exemplars separate the given query from any non-equivalent query. Therefore, LECQTER reduces the query equivalence problem to ...
