Variants

Select(ParsedSelect)

SELECT query

Union(ParsedUnion)

UNION / UNION ALL of two or more SELECT queries

CreateTable(ParsedCreateTable)

CREATE TABLE DDL

DropTable

DROP TABLE DDL.

if_exists = true corresponds to DROP TABLE IF EXISTS … — the executor returns Ok (rows_affected = 0) when the named table doesn’t exist, instead of TableNotFound. Idempotent drops were a v0.7.0 ROADMAP item until v0.6.2 picked up the fix while clearing test-infrastructure flake.
