# xk6-sql
**Use SQL databases from k6 tests.**
xk6-sql is a [Grafana k6 extension](https://grafana.com/docs/k6/latest/extensions/) that enables the use of SQL databases in [k6](https://grafana.com/docs/k6/latest/) tests.
## Usage
To use the xk6-sql API, the `k6/x/sql` module and the driver module corresponding to the database type should be imported. In the example below, `k6/x/sql/driver/ramsql` is the RamSQL database driver module.
The driver module exports a driver ID. This driver identifier should be used to identify the database driver to be used in the API functions.
**example**
```javascript file=examples/example.js
import sql from "k6/x/sql";
// the actual database driver should be used instead of ramsql
import driver from "k6/x/sql/driver/ramsql";
const db = sql.open(driver, "roster_db");
export function setup() {
db.exec(`
CREATE TABLE IF NOT EXISTS roster
(
id INTEGER PRIMARY KEY AUTOINCREMENT,
given_name VARCHAR NOT NULL,
family_name VARCHAR NOT NULL
);
`);
}
export function teardown() {
db.close();
}
export default function () {
let result = db.exec(`
INSERT INTO roster
(given_name, family_name)
VALUES
('Peter', 'Pan'),
('Wendy', 'Darling'),
('Tinker', 'Bell'),
('James', 'Hook');
`);
console.log(`${result.rowsAffected()} rows inserted`);
let rows = db.query("SELECT * FROM roster WHERE given_name = $1;", "Peter");
for (const row of rows) {
console.log(`${row.family_name}, ${row.given_name}`);
}
}
```
output

## Build
The [xk6](https://github.com/grafana/xk6) build tool can be used to build a k6 that will include **xk6-sql** extension and database drivers.
> [!IMPORTANT]
> In the command line bellow, **xk6-sql-driver-ramsql** is just an example, it should be replaced with the database driver extension you want to use.
> For example use `--with github.com/grafana/xk6-sql-driver-mysql` to access MySQL databases.
```bash
xk6 build --with github.com/grafana/xk6-sql@latest --with github.com/grafana/xk6-sql-driver-ramsql
```
For more build options and how to use xk6, check out the [xk6 documentation](https://github.com/grafana/xk6).
Supported RDBMSs includes: `mysql`, `postgres`, `sqlite3`, `sqlserver`, `azuresql`, `clickhouse`.
Check the [xk6-sql-driver GitHub topic](https://github.com/topics/xk6-sql-driver) to discover database driver extensions.
## Drivers
To use the xk6-sql extension, one or more database driver extensions should also be embedded. Database driver extension names typically start with the prefix `xk6-sql-driver-` followed by the name of the database, for example `xk6-sql-driver-mysql` is the name of the MySQL database driver extension.
For easier discovery, the `xk6-sql-driver` topic is included in the database driver extensions repository. The [xk6-sql-driver GitHub topic search](https://github.com/topics/xk6-sql-driver) therefore lists the available driver extensions.
### Create driver
Check the [grafana/xk6-sql-driver-ramsql](https://github.com/grafana/xk6-sql-driver-ramsql) template repository to create a new driver extension. This is a working driver extension with instructions in its README for customization.
[Postgres driver extension](https://github.com/grafana/xk6-sql-driver-postgres) and [MySQL driver extension](https://github.com/grafana/xk6-sql-driver-mysql) are also good examples.
