# Managing Datasources and Connections

A data source tells CrunchyFrog how to connect to a database. Depending on the database a data source needs provider specific information.

## Configure Data Sources

Data sources can be created, edited and deleted using the data source manager. To open the data source manager choose: Edit ‣ Data Sources.

A dialog with a notebook pops up. The notebook has two pages:

Data Sources
  Data Source configuration
Connections
  Database connection management (see About Database Connections)

To configure datasource select the Data Sources page.

### Create a New Data Source

To create a new data source, click on the New button. A new data source requires a name, the description is optional. Choose a database system from the drop down list. After choosing a database system additional database specific fields are displayed.

To test if all values are correct, click on the Test connection button. CrunchyFrog tries to open a connection to the database with the given values. If an error occurs it will be displayed in a popup window.

If everything is ok, save the new datasource using the Save button. The new data source will be listed in the list on the left.

### Edit a Data Source

To edit an existing data source select the data source from the list on the left. The values are displayed in the form and can be edited. Click Save to save your changes.

### Delete a Data Source

To delete a data source select the data source in the list on the left and click Delete.

### Connecting to a Database

To connect to a database use one of the following methods:

Datasource Manager
  Open the datasource manager (Edit ‣ Data Sources), choose the Connections page, select the datasource you want to connect to and click on the Connect button.
Navigator
  If you double-click a datasource in the navigator a connection to the database will be established and a new SQL editor opens with this connection assigned. If there’s already an active connection to this datasource the existing connection will be reused for the new SQL editor.
Menubar
  Select Query ‣ Connection to select an already opened connection or to open a new connection that should be assigned to the foreground editor.
Toolbar
  For an already opened SQL editor you can use the connection chooser widget in the toolbar to quickly select a connection. The connection chooser is bound to the currently active SQL editor.

Note

If you encounter troubles when connecting to Firebird, please refer to http://www.firebirdfaq.org/faq121/ for a possible solution.

### Default Connection for New Editors

Except when a editor is created by double clicking a datasource entry in the navigator, editors have no connection assigned by default. You can change this behavior by enabling the Use active connection as default in the preferences dialog. If this option is active, new editors use the same connection as the current foreground editor.

## About Database Connections

A data source can have multiple database connections opened at once. But the navigator is always using the first opened connection. SQL editors can use any database connection.

To keep track of the connections you have opened select Show connection from the connection chooser widget located at the toolbar. A handy dialog pops up where you can close and create connections. It has the same functionality as the Connections page on the data source manager.

Note

Database connections are shared between all main windows.
