# MySQL Setup
|
|
|
|
Configure Prisma with MySQL (or MariaDB).
|
|
|
|
## Prerequisites
|
|
|
|
- MySQL or MariaDB database
|
|
- Connection string
|
|
|
|
## 1. Schema Configuration
|
|
|
|
In `prisma/schema.prisma`:
|
|
|
|
```prisma
|
|
datasource db {
|
|
provider = "mysql"
|
|
}
|
|
|
|
generator client {
|
|
provider = "prisma-client"
|
|
output = "../generated"
|
|
}
|
|
```
|
|
|
|
## 2. Config Configuration
|
|
|
|
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="mysql://user:password@localhost:3306/mydb"
|
|
```
|
|
|
|
### Connection String Format
|
|
|
|
```
|
|
mysql://USER:PASSWORD@HOST:PORT/DATABASE
|
|
```
|
|
|
|
- **USER**: Database user
|
|
- **PASSWORD**: Password
|
|
- **HOST**: Hostname
|
|
- **PORT**: Port (default 3306)
|
|
- **DATABASE**: Database name
|
|
|
|
## Driver Adapter
|
|
|
|
Use a driver adapter for the standard SQL workflow.
|
|
|
|
1. Install adapter and driver:
|
|
```bash
|
|
npm install @prisma/adapter-mariadb mariadb
|
|
```
|
|
|
|
2. Instantiate Prisma Client with the adapter:
|
|
```typescript
|
|
import 'dotenv/config'
|
|
import { PrismaClient } from '../generated/client'
|
|
import { PrismaMariaDb } from '@prisma/adapter-mariadb'
|
|
|
|
const adapter = new PrismaMariaDb({
|
|
host: 'localhost',
|
|
port: 3306,
|
|
connectionLimit: 5,
|
|
user: process.env.MYSQL_USER,
|
|
password: process.env.MYSQL_PASSWORD,
|
|
database: process.env.MYSQL_DATABASE,
|
|
})
|
|
|
|
const prisma = new PrismaClient({ adapter })
|
|
```
|
|
|
|
### Text protocol option
|
|
|
|
If you need the MariaDB driver's text protocol instead of the default binary `execute()` path, enable `useTextProtocol` explicitly:
|
|
|
|
```typescript
|
|
import { PrismaClient } from '../generated/client'
|
|
import { PrismaMariaDb } from '@prisma/adapter-mariadb'
|
|
|
|
const adapter = new PrismaMariaDb(process.env.DATABASE_URL!, {
|
|
useTextProtocol: true,
|
|
})
|
|
|
|
const prisma = new PrismaClient({ adapter })
|
|
```
|
|
|
|
Use this only when you specifically need text-protocol compatibility for your MariaDB setup.
|
|
|
|
## PlanetScale Setup
|
|
|
|
PlanetScale uses MySQL but requires specific settings because it doesn't support foreign key constraints.
|
|
|
|
In `prisma/schema.prisma`:
|
|
|
|
```prisma
|
|
datasource db {
|
|
provider = "mysql"
|
|
relationMode = "prisma" // Emulate foreign keys in Prisma
|
|
}
|
|
```
|
|
|
|
## Common Issues
|
|
|
|
### "Too many connections"
|
|
MySQL has a connection limit. Adjust connection pool size in URL:
|
|
```env
|
|
DATABASE_URL="mysql://...?connection_limit=5"
|
|
```
|
|
|
|
### JSON Support
|
|
MySQL 5.7+ supports JSON. MariaDB 10.2+ supports JSON (as an alias for LONGTEXT with check constraints). Prisma handles this, but verify your version.
