SQL

Natural language to SQL query generation evaluates text-to-query fidelity and schema reasoning. This task is particularly relevant for analytics chat assistants and simplified database interfaces where users need to query data using natural language. Models must understand both the intent behind the question and the structure of the underlying database schema.

BEGIN;
ALTER TABLE completions ADD COLUMN course_id INT;
UPDATE completions c
SET course_id = l.course_id
FROM lessons l
WHERE l.lesson_id = c.lesson_id;
ALTER TABLE completions ALTER COLUMN course_id SET NOT NULL;
ALTER TABLE completions
ADD CONSTRAINT completions_enrollment_fk
FOREIGN KEY (user_id, course_id)
REFERENCES enrollments (user_id, course_id);
