# xk6-sql
This is a [k6](https://github.com/grafana/k6) extension using the
[xk6](https://github.com/grafana/xk6) system.
Supported RDBMSs: `mysql`, `postgres`, `sqlite3`, `sqlserver`. See the [tests](tests)
directory for examples. Other RDBMSs are not supported, see
[details below](#support-for-other-rdbmss).
Based on [xk6-sql] (https://github.com/msaf1980/xk6-sql) exrension, but also support naming parameters.
## Build
To build a `k6` binary with this plugin, first ensure you have the prerequisites:
- [Go toolchain](https://go101.org/article/go-toolchain.html)
- If you're using SQLite, a build toolchain for your system that includes `gcc` or
another C compiler. On Debian and derivatives install the `build-essential`
package. On Windows you can use [tdm-gcc](https://jmeubank.github.io/tdm-gcc/).
Make sure that `gcc` is in your `PATH`.
- Git
Then:
1. Install `xk6`:
```shell
go install go.k6.io/xk6/cmd/xk6@latest
```
2. Build the binary:
```shell
xk6 build --with github.com/msaf1980/xk6-sqlx
```
If you're using SQLite, ensure you have a C compiler installed (see the
prerequisites note) and set `CGO_ENABLED=1` in the environment:
```shell
CGO_ENABLED=1 xk6 build --with github.com/msaf1980/xk6-sqlx
```
On Windows this is done slightly differently:
```shell
set CGO_ENABLED=1
xk6 build --with github.com/msaf1980/xk6-sqlx
```
## Development
To make development a little smoother, use the `Makefile` in the root folder. The default target will format your code, run tests, and create a `k6` binary with your local code rather than from GitHub.
```bash
make
```
Once built, you can run your newly extended `k6` using:
```shell
./k6 run tests/sqlite3_test.js
```
## Example
```javascript
// script.js
import sql from 'k6/x/sql';
const db = sql.open("sqlite3", "./test.db");
export function setup() {
db.exec(`CREATE TABLE IF NOT EXISTS keyvalues (
id integer PRIMARY KEY AUTOINCREMENT,
key varchar NOT NULL,
value varchar);`);
}
export function teardown() {
db.close();
}
export default function () {
db.exec("INSERT INTO keyvalues (key, value) VALUES('plugin-name', 'k6-plugin-sql');");
let results = sql.query(db, "SELECT * FROM keyvalues;");
for (const row of results) {
console.log(`key: ${row.key}, value: ${row.value}`);
}
}
```
Result output:
```shell
$ ./k6 run script.js

### Support for other RDBMSs
Note that this project is not accepting support for additional SQL implementations
and RDBMSs. See the discussion in [issue #17](https://github.com/grafana/xk6-sql/issues/17)
for the reasoning.
