A Prisma driver adapter maps the ORM to a concrete database driver by defining interfaces, lifecycle hooks, and error mapping. It connects Prisma v7 directly to database engines like PostgreSQL, SQLite, MySQL, and SQL Server, bypassing standard engine communication.

You manage transaction isolation levels in a Prisma driver adapter by implementing specific transaction lifecycle hooks within the SqlDriverAdapter. This skill details how to handle transactions, script execution, and connection management to ensure production-grade reliability.

Mapping database errors in a Prisma SqlDriverAdapter implementation requires wrapping concrete database driver errors into Prisma's expected error format. This skill provides error mapping guidance along with a verification checklist to ensure correct integration across PostgreSQL, MySQL, SQLite, and SQL Server.

Yes, you can use a Prisma driver adapter with SQLite and PostgreSQL. The adapter implementation patterns apply to building or modifying SqlDriverAdapter implementations for PostgreSQL, MySQL, SQLite, and SQL Server, including specific testing strategies for each database provider.

Building a Prisma v7 SqlDriverAdapter requires satisfying concrete specifications for the provider, adapterName, query and execute methods, and error wrapping. You must also implement transactions with proper isolation levels and pass a verification checklist to ensure production readiness.

Testing a custom Prisma driver adapter implementation involves following specific testing strategies and a verification checklist provided by this skill. This ensures your SqlDriverAdapter correctly handles query execution, transaction lifecycles, and error mapping for your target database provider.
