# Database

In order to connect a database agent to aqua, you have to go through the following steps. First, extract the database agent zip file and open the <mark style="color:orange;">**aquaAgentDatabaseGui.exe.config**</mark>.&#x20;

Here, enter the agentCode and the aquaServiceURL.&#x20;

{% code overflow="wrap" %}

```csharp
  <add key="agentCode" value="yd7zhzc5bd2fiydkyu9j"/> 
  <add key="aquaServiceUrl" value="http://youraquaserver/aquaAPI/aquaagentwebservice.asmx"/> 
```

{% endcode %}

The rest of the config file is not necessary to connect the agent to aqua. The agent code is generated in aqua, and assigned to the agent.&#x20;

Next, click onto Connections in the Agent Server Configuration in order to define the database. &#x20;

Within the test case, you can insert a database test script. The connection has to be defined in the drop-down box, the query has to be inserted, and there is an option to enter a check value. In order to use variables, place them between '&', e.g.: A variable called '*User*' can be used in the query or in the expected results as '*\&User&*'.
