## Summary - Added **46 new queries** (Q511-Q556) to the query agent regression suite, bringing the total from 524 to **570 unique queries** - Mined from real production SQL patterns (june7.sql) and adapted to use existing test data fields - Fixed **15 pre-existing duplicate IDs** (Q226-Q240 existed in both aggregation.json and basic_select.json — renumbered to Q557-Q571) ## New query distribution | Category | New | Description | |---|---|---| | string_functions | +10 | spath() + str_match_ignore_case, split_part() + chr(), multi-COALESCE chains, CAST AS VARCHAR | | histogram | +7 | 30-second/min intervals, COUNT FILTER, SUM(CASE WHEN), NULL breakdowns | | date_time | +6 | arrow_cast(), date_trunc(), to_timestamp_micros(), timestamp arithmetic, LAG for gaps | | combined | +6 | count(distinct) in CASE WHEN, re_match + re_not_match combo, FILTER in aggregation, HAVING percentages | | full_text_search | +5 | re_match + re_not_match, regexp_like, match_all(), str_match_ignore_case with COALESCE | | cte_subquery | +4 | CTE with spath, CTE with COALESCE fallbacks, correlated subquery | | aggregation | +2 | IS NOT NULL exploration patterns, multi-column GROUP BY | | window | +2 | NTILE with COALESCE PARTITION, LAG with delta calculation | | basic_select | +2 | Complex COALESCE + CAST chains, NULLS LAST ordering | | cross_stream | +1 | LEFT JOIN on dual keys across streams | | union | +1 | UNION ALL with different metric types | ## New OO-specific functions covered Four functions previously had **zero test coverage**: - `chr()` — 1 query (string splitting by character code) - `arrow_cast()` — 1 query (DataFusion timestamp arithmetic) - `date_trunc()` — 1 query (minute-level timestamp bucketing) - `to_timestamp_micros()` — 1 query (microsecond-to-timestamp conversion) Plus expanded coverage of rare functions: `spath()` (+3), `split_part()` (+3). ## Test modes - **38/46** new queries have full sqllogictest comparison (DuckDB computed expected results) - **8/46** use legacy assertions for OO-specific functions that DuckDB cannot replicate (spath, arrow_cast, date_trunc, to_timestamp_micros) - Overall suite: **533** sqllogictest, **37** legacy ## Changes | File | Change | |---|---| | `data_gen.py` | `NUM_QUERIES` 520 → 575 | | `gen_q511_q556.py` | New: query generation script | | 13 category JSON files | Updated with new queries + dedup fix | ## Verification - `compute_counts.py` ran successfully on all 570 queries - 0 duplicate IDs across all 13 category files - Only gap: Q025 (pre-existing) 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com>
