# SQLi testing labs

You can use this script to spin up four databases, MySQL, Oracle, SQL Server and PostgreSQL. It's useful for:

* Learning SQL
* Testing SQL statements
* Testing SQL injection payloads

```
version: '3'

services:
  mysql:
    image: mysql:8.0
    environment:
      MYSQL_ROOT_PASSWORD: root_password
      MYSQL_DATABASE: test_db
    ports:
      - "3306:3306"

  sqlserver:
    image: mcr.microsoft.com/mssql/server:2019-latest
    environment:
      SA_PASSWORD: "Strong!Passw0rd"
      ACCEPT_EULA: "Y"

```

## Quick start

### Postgresql

Connect to PostgreSQL.

```
psql -h localhost -p 5432 -U postgres -W
```

Common commands.

```
# List databases
\l
\list

# Connect to a database
\c <database>

# List tables
\dt

# Basic query
SELECT * FROM <table-name>;
```

### MySQL

Connect to MySQL.

```
mysql -h localhost -P 3306 -u root -p
```

Common commands.

```
# List databases
SHOW DATABASES;

# Connect to a database
USE <database>;

# List tables
SHOW TABLES;

# Basic query
SELECT * FROM <table-name>;
```

### Oracle

Connect to Oracle.

{% hint style="info" %}
You can install the oracle client and configure it locally on your Kali machine, but it's easier to just connect to the container and work locally there.&#x20;
{% endhint %}

```
# Connect to your container
sudo docker ps -a
sudo docker exec -it <container-id> bash

sqlplus system/oracle@localhost:1521/xe
```

Common commands.

```
# List tables
SELECT table_name FROM user_tables;

# Basic query
SELECT * FROM table_name;
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://appsecexplained.gitbook.io/appsecexplained/scripts/docker-compose.yml-files/sqli-testing-labs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
