Prisma SQL Driver Adapter Implementation

Use this guide with the exact @prisma/driver-adapter-utils version installed by the target Prisma release. Driver adapters are a protocol boundary: type-compatible code can still corrupt values, leak connections, or break transactions.

When to Apply

• Implementing SqlDriverAdapterFactory, SqlMigrationAwareDriverAdapterFactory, SqlDriverAdapter, or Transaction
• Adding nested-transaction/savepoint support
• Mapping driver values, column metadata, bind arguments, or database errors
• Debugging P2039, transaction leaks, shadow-database failures, or adapter-specific query behavior
