UI Configuration

The UI of the DBQuery mediator changes depending on whether you connect to the database using a connection pool, or using a data source. Click on the relevant tab to view the required UI.

...

This example demonstrates simple database write operations. The DB Report mediator writes to a table using the details of the message. It updates the stock price of the company using the last quote value, which is calculated by evaluating an XPath expression against the response message.
