1. The document discusses how to use the Mule Database component to call stored procedures with input and output parameters to retrieve data from a database. 2. An example Mule flow is provided that calls a stored procedure using the Database component, passing an input parameter and returning the output parameter value in the payload. 3. The flow listens for HTTP requests, calls the stored procedure to look up a state name based on a geo code parameter, and logs the state name returned in the payload.

Stored Procedure

2. Abstract
• The main motto of this PPT is how to use Database component using
stored procedure call in our mule applications.

3. Introduction
• The Database component can also use to call stored procedure call
with In and Out parameters to get the results from DB, then returns
the original message as Map having required column names as keys
and column values as values to the flow.

4. Example

7. • Flow of execution:
1. URL to trigger the service from browser
http://localhost:8083/procedure?geocode=63573
2. Database component connects to the specific
database, executes the selected procedure by
taking and prints the result as Map.
