* fix(mysql): validate parameter count for prepared statements Add validation to ensure the number of provided parameters matches the expected count for MySQL prepared statements. This prevents protocol errors by returning an error if the counts do not match before sending the statement for execution. * refactor(mysql): use err_protocol macro for error creation Replace direct Error::Protocol(format!()) calls with err_protocol! macro in MySQL connection executor. * test(mysql): add parameter count validation tests - Add test for too few parameters provided to query - Add test for too many parameters provided to query - Add test for parameters provided when none expected - All tests verify Error::Protocol is returned for mismatches Covers cases for issue #3774 parameter validation fix.
Running Tests
SQLx uses docker to run many compatible database systems for integration testing. You'll need to install docker to run the full suite. You can validate your docker installation with:
$ docker run hello-world
Start the databases with docker-compose
before running tests:
$ docker-compose up
Run all tests against all supported databases using:
$ ./x.py
If you see test failures, or want to run a more specific set of tests against a specific database, you can specify both the features to be tests and the DATABASE_URL. e.g.
$ DATABASE_URL=mysql://root:password@127.0.0.1:49183/sqlx cargo test --no-default-features --features macros,offline,any,all-types,mysql,runtime-async-std-native-tls
