JDBC Component

The jdbc: component allows enables you to work with access databases using through JDBC, where SQL queries and operations via SQL text as are sent in the message payloadbody.
This component uses the standard Java JDBC to work with the databaseAPI, unlike the SQL Component component that , which uses spring-jdbc.

URI format

jdbc:dataSourceName[?options]

This component only supports producer , meaning that you can not use routes with this component in the from typeendpoints.

You can append query options to the URI in the following format, ?option=value&option=value&...

Options

...

The result is returned in the OUT body as a an ArrayList<HashMap<String, Object>> list object with the result. The List object contains the list of rows and the Map contains objects contain each row with the string String key as the column name.

Note: This component fetches ResultSetMetaData to be able to return the column name as the key in the Map.

Samples

In the sample below following example, we fetch the rows from the customer table.

First we register our datasource in the Camel registry as testdb:

{snippet:id=register|lang=java|url=camel/trunk/components/camel-jdbc/src/test/java/org/apache/camel/component/jdbc/JdbcRouteTest.java}

Then we configure a route that routes to the JDBC component, so the SQL will be executed, notice that . Note how we refer to the testdb datasource that was bound in the previous step:

{snippet:id=route|lang=java|url=camel/trunk/components/camel-jdbc/src/test/java/org/apache/camel/component/jdbc/JdbcRouteTest.java}

Or you can create a datasource DataSource in Spring like this:

{snippet:id=example|lang=java|url=camel/trunk/components/camel-jdbc/src/test/resources/org/apache/camel/component/jdbc/camelContext.xml}

And then we We create the endpoint and sends the exchange containing an endpoint, add the SQL query to execute in the in bodybody of the IN message, and then send the exchange. The result of the query is returned in the out OUT body.:

{snippet:id=invoke|lang=java|url=camel/trunk/components/camel-jdbc/src/test/java/org/apache/camel/component/jdbc/JdbcRouteTest.java}

...

If we want to poll a database using this the JDBC component, we need to combine this it with a polling scheduler such as the Timer or Quartz etc.
In this sample In the following example, we retrieve data from the database every 60th 60 seconds.:

from("timer://foo?period=60000").setBody(constant("select * from customer")).to("jdbc:testdb").to("activemq:queue:customers");
