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✓ WorkedIt resolved the vague phrase best customers as highest order count plus highest total spend instead of asking for a definition.Business Insight⚠ StruggledIt produced query descriptions, but no after-the-table narrative that distilled the result into a takeaway like which top customer had unpaid orders.Follow-Up Context✓ WorkedIt kept the top 3 from that list context intact across both follow-ups and continued analyzing the same three customers.Result Readability⚠ StruggledAll three best-customer result tables keep customer_id as the lead column, so the output stays UUID-heavy and hard to scan.SQL Generation✓ WorkedAcross the three turns it generated production-grade SQL, including ranking logic, unpaid-order checks, and payment-method aggregation with CTEs, ROW_NUMBER, COALESCE, and LEFT JOIN.

AskYourDatabase✓ WorkedIt can interpret informal ranking language like 'the ones who order the most and spend the most' and launch the analysis directly.Basedash✓ WorkedIt correctly handled a conversational, multi-part customer question without requiring SQL, producing two rankings plus follow-up answers.Definite◐ MixedIt accepted the natural-language request but only ranked customers by total spend, so it did not fully understand the combined 'order the most and spend the most' intent.FutureSmart NL2SQL Agent✓ WorkedAccepts the best-customers question in plain English and returns a ranked answer without requiring SQL from the user.Querio✓ WorkedHandles an informal conversational request and splits 'order the most' and 'spend the most' into two separate ranking dimensions instead of guessing.
