+# SQL Server Setup
+
+Configure Prisma with Microsoft SQL Server.
+
+## Prerequisites
+
+- SQL Server 2017, 2019, 2022, or Azure SQL
+- TCP/IP enabled
+
+## 1. Schema Configuration
+
+In `prisma/schema.prisma`:
+
+```prisma
+datasource db {
+  provider = "sqlserver"
+}
+
+generator client {
+  provider = "prisma-client"
+  output   = "../generated"
+}
+```
+
+## 2. Config Configuration (v7)
+
+In `prisma.config.ts`:
+
+```typescript
+import { defineConfig, env } from 'prisma/config'
+
+export default defineConfig({
+  schema: 'prisma/schema.prisma',
+  datasource: {
+    url: env('DATABASE_URL'),
+  },
+})
+```
+
+## 3. Environment Variable
+
+In `.env`:
+
+```env
+DATABASE_URL="sqlserver://localhost:1433;database=mydb;user=sa;password=Password123;encrypt=true;trustServerCertificate=true"
+```
+
+### Connection String Format
+
+```
+sqlserver://HOST:PORT;database=DB;user=USER;password=PASS;encrypt=true;trustServerCertificate=true
+```
+
+- **encrypt**: Required for Azure (true).
+- **trustServerCertificate**: True for self-signed certs (local dev).
+
+## Driver Adapter (Prisma ORM 7 required)
+
+Prisma ORM 7 uses the query compiler by default, so you must use a driver adapter.
+
+1. Install adapter and driver:
+   ```bash
+   npm install @prisma/adapter-mssql mssql
+   ```
+
+2. Instantiate Prisma Client with the adapter:
+   ```typescript
+   import 'dotenv/config'
+   import { PrismaClient } from '../generated/client'
+   import { PrismaMssql } from '@prisma/adapter-mssql'
+
+   const adapter = new PrismaMssql({
+     server: 'localhost',
+     port: 1433,
+     database: 'mydb',
+     user: process.env.SQLSERVER_USER,
+     password: process.env.SQLSERVER_PASSWORD,
+     options: {
+       encrypt: true,
+       trustServerCertificate: true,
+     },
+   })
+
+   const prisma = new PrismaClient({ adapter })
+   ```
+
+## Common Issues
+
+### "Login failed for user"
+- SQL Server auth vs Windows auth. Prisma typically uses SQL Server authentication (username/password).
+- Ensure TCP/IP is enabled in SQL Server Configuration Manager.
+
+### "Table not found" (dbo schema)
+Prisma assumes `dbo` schema by default. If using another schema, update the model or connection string? SQL Server provider mostly sticks to default schema.
