What was measured

Plain English Query Handling

Can the tool understand business questions without SQL?

decisive for this rankingtransformation

This is the core of the ranking: the tool must understand a business question without the user writing SQL. (3 of 3 judges)

What was given, what came back

Test input: Best customers with unpaid-order and payment-method follow-ups · text · group: live-database-plain-english-queries

Input — what we sent

The exact prompt

Who are my best customers — the ones who order the most and spend the most?

Follow-up 1: For the top 3 from that list — do any of them have unpaid orders?

Follow-up 2: What payment methods do these top 3 usually use?

A conversational multi-table customer analysis with follow-up questions. It asks for the best customers by both order volume and spend, then drills into unpaid orders for the top 3 and their usual payment methods. Designed to test ranking logic, join-heavy analysis, and follow-up context retention.

Why this input is hard

· ambiguous business term interpretation
· multi-table joins
· aggregation and ranking
· follow-up context retention
· scoping to a selected subset
· payment behavior analysis

Output — unretouched

Ambiguity Handling✓ WorkedResolves the ambiguous phrase 'best customers' by answering with both top-by-orders and top-by-spend views rather than silently choosing one.Follow-Up Context✓ WorkedRetains follow-up context perfectly, reusing the same top-3 customer UUIDs in both later questions.Result Readability◐ MixedThe answer is usable, but it is less readable than it could be because the output centers customer UUIDs instead of human names.SQL Generation✓ WorkedGenerates the ranking SQL and the follow-up SQL correctly across the three-turn customer analysis chain.
