…sql (#21678) ~~This adds a high level test that should pass if/when prisma/prisma-engines#4375 is merged.~~ Transactions are now handled inside this repository, so the update to prisma-engines is no longer required. This change adds support for handling rollbacks in nested transactions in SQL databases. Specifically, the inner transaction should be rolled back if the outer transaction fails. To do this we keep track of the transaction ID and transaction depth so we can re-use an existing open transaction in the underlying engine. This change also allows the use of the `$transaction` method on an interactive transaction client. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Nested interactive transactions for SQL databases (Postgres, MySQL, SQLite, SQL Server) via savepoints; MongoDB remains without nested-transaction support. * **Tests** * Added extensive nested-transaction tests covering multi-level nesting, savepoint behavior, rollback/commit propagation, concurrency and provider-specific syntax. * **Documentation** * Updated runtime documentation to describe nested transaction behavior and provider-specific savepoint semantics. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Jacek Malec <malec@prisma.io>
