|
|
|
|
Microsoft SQL Server is a relational database management system developed by Microsoft, designed for enterprise-level data storage, management, and analytics with robust security and scalability features.
|
|
Read more [here](https://en.wikipedia.org/wiki/Microsoft_SQL_Server).
|
|
|
|
## Example Usage
|
|
|
|
Make sure you have MS SQL installed and configured.
|
|
Then, you can connect it straight into Better Auth.
|
|
|
|
```ts title="auth.ts"
|
|
import { betterAuth } from "better-auth";
|
|
import { MssqlDialect } from "kysely";
|
|
import * as Tedious from 'tedious'
|
|
import * as Tarn from 'tarn'
|
|
|
|
const dialect = new MssqlDialect({
|
|
tarn: {
|
|
...Tarn,
|
|
options: {
|
|
min: 0,
|
|
max: 10,
|
|
},
|
|
},
|
|
tedious: {
|
|
...Tedious,
|
|
connectionFactory: () => new Tedious.Connection({
|
|
authentication: {
|
|
options: {
|
|
password: 'password',
|
|
userName: 'username',
|
|
},
|
|
type: 'default',
|
|
},
|
|
options: {
|
|
database: 'some_db',
|
|
port: 1433,
|
|
trustServerCertificate: true,
|
|
},
|
|
server: 'localhost',
|
|
}),
|
|
},
|
|
})
|
|
|
|
export const auth = betterAuth({
|
|
database: {
|
|
dialect,
|
|
type: "mssql"
|
|
}
|
|
});
|
|
|
|
|
|
```
|
|
<Callout>
|
|
For more information, read Kysely's documentation to the [MssqlDialect](https://kysely-org.github.io/kysely-apidoc/classes/MssqlDialect.html).

|
## Schema generation & migration
|
|
|
|
The [Better Auth CLI](/docs/concepts/cli) allows you to generate or migrate
|
|
your database schema based on your Better Auth configuration and plugins.
|
|
|
|
<table>
|
|
<tr className="border-b">
|
|
<th>
|
|
<p className="font-bold text-[16px] mb-1">MS SQL Schema Generation</p>
|
|
</th>
|
|
<th>
|
|
<p className="font-bold text-[16px] mb-1">MS SQL Schema Migration</p>
|
|
</th>
|
|
</tr>
|
|
<tr className="h-10">
|
|
<td>✅ Supported</td>
|
|
<td>✅ Supported</td>
|
|
</tr>
|
|
</table>
|
|
|
|
```bash title="Schema Generation"
|
|
npx @better-auth/cli@latest generate
|
|
```
|
|
|
|
```bash title="Schema Migration"
|
|
npx @better-auth/cli@latest migrate
|
|
```
|
|
|
|
## Additional Information
|
|
|
|
MS SQL is supported under the hood via the [Kysely](https://kysely.dev/) adapter, any database supported by Kysely would also be supported. (<Link href="/docs/adapters/other-relational-databases">Read more here</Link>)
