# Description of Changes - Added a query builder for C++ module bindings - Added query-builder table/filter/join types - Added semijoin support with compile-time checks for lookup-table and indexed-field usage - Added support for returning query-builder queries from C++ views - Hooked query-builder metadata into the C++ table/view macros and V10 module-def path - Added test coverage for the new C++ query-builder behavior - Compile tests for pass/fail cases - SQL tests for generated query output - Added a C++ test module for view primary key coverage - **Update:** Switched the core to pass the columns and index-columns metadata with the table source for better client-side codegen to have some shared code between server + client. # API and ABI breaking changes - No intended API or ABI breaking changes - Adds a new public query-builder API to the C++ bindings - C++ views can now return query-builder query types in addition to materialized row results # Expected complexity level and risk 3 - Mostly contained to C++ bindings, but it touches macros, view registration/serialization, and module-def generation, so there are a few places where the pieces need to stay in sync. # Testing I've done end to end testing of I think every type as well as built some tests to confirm the SQL output. - [x] Run the C++ query-builder SQL tests [crates/bindings-cpp/tests/query-builder-compile/run_query_builder_compile_tests.sh] - [x] Smoke test a generated C++ module using query-builder views --------- Signed-off-by: Jason Larabie <jason@clockworklabs.io> Co-authored-by: Ryan <r.ekhoff@clockworklabs.io> Co-authored-by: Zeke Foppa <196249+bfops@users.noreply.github.com>
sdk-test-view-pk-cpp
C++ implementation of the SpacetimeDB query-builder view PK test module.
This mirrors the Rust sdk-test-view-pk
and C# sdk-test-view-pk-cs modules.
Coverage
- query-returning views over base tables
- PK-preserving query views
- right semijoins from indexed membership tables to player rows
Views

Build
.\modules\sdk-test-view-pk-cpp\compile.bat
The output will be modules/sdk-test-view-pk-cpp/build/lib.wasm.
