# DBDataSourceServer

## Overview

`DBDataSourceServer` provides runtime access to a database server within Servoy applications, accessible via `datasources.db.<server_name>`. This object enables interaction with database servers, including the ability to define client-specific connections, retrieve server names, and access tables within the server. For further details on configuring connections, refer to the [JSConnectionDefinition](https://docs.servoy.com/reference/servoycore/dev-api/datasources/jsconnectiondefinition) documentation.

## Methods Detailed

### defineClientConnection()

Define a client connection for this server, you can configure the Database Server to create connections for current client using properties of this JSConnectionDefinition.\
All interaction with the database will go over a connection coming from a specific client pool with that is created for this client.\
Things like username, password or connection properties can be adjusted.

**Returns:** [JSConnectionDefinition](/reference/servoycore/dev-api/datasources/jsconnectiondefinition.md) DBDataSourceServer server

**Sample**

```js
var conncetionDefinition = datasources.db.example_data.defineClientConnection().setProperty('key', 'value').create();
```

### getDataModelCloneFrom()

Get the server where this server is a data model clone from.

**Returns:** [DBDataSourceServer](/reference/servoycore/dev-api/datasources/dbdatasourceserver.md) DBDataSourceServer server

**Sample**

```js
datasources.db.example_data.getDataModelCloneFrom().getServerName()
```

### getServerName()

Get the server name.

**Returns:** [String](/reference/servoycore/dev-api/js-lib/string.md) String server name

**Sample**

```js
datasources.db.example_data.getServerName() // returns 'example_data'
```

### getTableNames()

Returns an array with the names of all tables of this server.

**Returns:** [Array](/reference/servoycore/dev-api/js-lib/array.md) String\[] server table names;

**Sample**

```js
datasources.db.example_data.getTableNames()
```
