Frequently asked questions

Does AI2SQL know ClickHouse functions? +

Yes — uniq/uniqExact, quantile combinators, arrayJoin and date functions are generated natively, not approximated with ANSI SQL.

Can it design MergeTree tables? +

Yes — describe your workload and get CREATE TABLE with sensible ORDER BY and partition keys, plus materialized-view rollups.

Is there index advice? +

ClickHouse has sparse primary indexes; the optimizer suggests ORDER BY and skip-index changes instead of classic indexes.
