From 2ca973fb7c1e730529b6e5e7fec691f91169f309 Mon Sep 17 00:00:00 2001 From: Egutierrez Date: Wed, 13 May 2026 00:58:18 +0200 Subject: [PATCH] feat(playground): DuckDB adapter para TQL->SQL execute (issue 0080) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cierra 0080 fase 11. tql_duckdb.{h,cpp} es adapter opcional gated por build flag FN_TQL_DUCKDB=ON. Default OFF — playground sin deps DuckDB. Funcionalidad: - tql_duckdb::execute(sql, params, tables) -> Result con StageOutput materializado. Abre DuckDB :memory:, registra TableInputs via CREATE TABLE + INSERT batched (1000 rows/batch), prepare + bind params via duckdb_bind_varchar, execute_prepared, materializa resultado via duckdb_value_varchar + duckdb_free. - type_from_duckdb mapeo DuckDB type -> ColumnType. - CMakeLists.txt: option(FN_TQL_DUCKDB) + condicional add a sources + link duckdb_vendored + copy runtime. - data_table.cpp Ask AI modal: ifdef FN_TQL_DUCKDB para status message apropiado en SQL apply. - self_test.cpp: 4 round-trip tests gated por FN_TQL_DUCKDB: stage0 SELECT, group+count, filter Op::Eq, sum aggregation (verifica sum_n(go)=30). Tests: - 603 passed sin FN_TQL_DUCKDB (default OFF). - 618 passed con FN_TQL_DUCKDB=ON (round-trip TQL emit -> DuckDB execute -> match compute_stage pure). - e2e linux + windows cross-build OK ambos modos.
