TypedSQL is a brand new way to interact with your database from Prisma Client. After enabling the typedSql Preview feature, you’re able to write SQL queries in a new sql subdirectory of your prisma directory. These queries are then checked by Prisma during using the new --sql flag of prisma generate and added to your client for use in your code.

To get started with TypedSQL:

Make sure that you have the latest version of prisma and @prisma/client installed:
```
npm install -D prisma@latest
npm install @prisma/client@latest
```

Enable the typedSql Preview feature in your Prisma Schema.

   generator client {
     provider = "prisma-client-js"
     previewFeatures = ["typedSql"]
   }

Create a sql subdirectory of your prisma directory.
```
mkdir -p prisma/sql
```
You can now add .sql files to the sql directory! Each file can contain one sql query and the name must be a valid JS identifier. For this example, say you had the file getUsersWithPosts.sql with the following contents:
```
SELECT u.id, u.name, COUNT(p.id) as "postCount"
FROM "User" u
LEFT JOIN "Post" p ON u.id = p."authorId"
GROUP BY u.id, u.name
```

Import your SQL query into your code with the @prisma/client/sql import:

   import { PrismaClient } from '@prisma/client'
   import { getUsersWithPosts } from '@prisma/client/sql'

   const prisma = new PrismaClient()

   const usersWithPostCounts = await prisma.$queryRawTyped(getUsersWithPosts)
   console.log(usersWithPostCounts)

There’s a lot more to talk about with TypedSQL. We think that the combination of the high-level Prisma Client API and the low-level TypedSQL will make for a great developer experience for all of our users.

Bug fixes

Driver adapters and D1

A few issues with our driverAdapters Preview feature and Cloudflare D1 support were resolved via https://github.com/prisma/prisma-engines/pull/4970 and https://github.com/prisma/prisma/pull/24922 - Mathematic operations such as max, min, eq, etc in queries when using Cloudflare D1. - Resolved issues when comparing BigInt IDs when relationMode="prisma" was enabled and Cloudflare D1 was being used.

https://github.com/prisma/prisma/issues/23742 fixes Prisma Client not supporting deeply nested some clauses when the relationJoins Preview feature was enabled.

MongoDB

The MongoDB driver for Rust (that our query engine users under the hood) had behavior that prioritized IPv4 connections over IPv6 connections. In IPv6-only environments, this could lead to significant "cold starts" where the query engine had to wait for IPv4 to fail before the driver would try IPv6.

With help from the MongoDB team, this has been resolved. The driver will now try IPv4 and IPv6 connections in parallel and then move forward with the first response. This should prevent cold start issues that have been seen with MongoDB in Prisma Accelerate.

Thank you to the MongoDB team!
