This component can only be used to define producer endpoints, which means that you cannot use the JDBC component in a from() statement.

URI format

-

This component only supports producer endpoints.

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

Options

Name

Default Value

Description

readSize

0

The default maximum number of rows that can be read by a polling query. The default value is 0.

statement.<xxx>

null

Camel 2.1: Sets additional options on the java.sql.Statement that is used behind the scenes to execute the queries. For instance, statement.maxRows=10. For detailed documentation, see the java.sql.Statement javadoc documentation.

useJDBC4ColumnNameAndLabelSemantics

true

Camel 2.2: Sets whether to use JDBC 4/3 column label/name semantics. You can use this option to turn it false in case you have issues with your JDBC driver to select data. This only applies when using SQL SELECT using aliases (e.g. SQL SELECT id as identifier, name as given_name from persons).

resetAutoCommit

true

Camel 2.9: If true, Camel will set the autoCommit on the JDBC connection to be false, commit the change after executing the statement and reset the autoCommit flag of the connection at the end. If the JDBC connection does not support resetting the autoCommit flag, set this to false.
When used with XA transactions you most likely need to set it to false so that the transaction manager is in charge of committing this tx.

allowNamedParameters

true

Camel 2.12: Whether to allow using named parameters in the queries.

prepareStatementStrategy

 

Camel 2.12: Allows to plugin to use a custom org.apache.camel.component.jdbc.JdbcPrepareStatementStrategy to control preparation of the query and prepared statement.

useHeadersAsParameters

false

Camel 2.12: Set this option to true to use the prepareStatementStrategy with named parameters. This allows to define queries with named plac eholders, and use headers with the dynamic values for the query placeholders.

outputType

SelectList

Camel 2.12.1: Make the output of the producer to SelectList as List of Map, or SelectOne as single Java object in the following way:
a) If the query has only single column, then that JDBC Column object is returned. (such as SELECT COUNT( * ) FROM PROJECT will return a Long object.
b) If the query has more than one column, then it will return a Map of that result.
c) If the outputClass is set, then it will convert the query result into an Java bean object by calling all the setters that match the column names. It will assume your class has a default constructor to create instance with. From Camel 2.1 4 onwards then SelectList is also supported.
d) If the query resulted in more than one rows, it throws an non-unique result exception.
Camel 2.14.0: New StreamList output type value that streams the result of the query using an Iterator<Map<String, Object>>, it can be used along with the Splitter EIP.

outputClass

null

Camel 2.12.1: Specify the full package and class name to use as conversion when outputType=SelectOne. From Camel 2.14 onwards then SelectList is also supported.

beanRowMapper

 

Camel 2.12.1: To use a custom org.apache.camel.component.jdbc.BeanRowMapper when using outputClass. The default implementation will lower case the row names and skip underscores, and dashes. For example "CUST_ID" is mapped as "custId".

useGetBytesForBlobfalseCamel 2.16: To read BLOB columns as bytes instead of string data. This may be needed for certain databases such as Oracle where you must read BLOB columns as bytes.

Result

By default the result is returned in the OUT body as an ArrayList<HashMap<String, Object>>. Th e List object contains the list of rows and the Map objects contain each row with the String key as the column name. You can use the option outputType to control the result.

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

Message Headers

Header

Description

CamelJdbcRowCount

If the query is a SELECT, query the row count is returned in this OUT header.

CamelJdbcUpdateCount

If the query is an UPDATE, query the update count is returned in this OUT header.

CamelGeneratedKeysRows

Camel 2.10: Rows that contains the generated kets.

CamelGeneratedKeysRowCount

Camel 2.10: The number of rows in the header that contains generated keys.

CamelJdbcColumnNames

Camel 2.11.1: The column names from the ResultSet as a java.util.Set type.

CamelJdbcParamete s

Camel 2.12: A java.util.Map which has the headers to be used if useHeadersAsParameters has been enabled.

Generated keys

Available as of Camel 2.10

If you insert data using SQL INSERT, then the RDBMS may support auto generated keys. You can instruct the JDBC producer to return the generated keys in headers.
To do that set the header CamelRetrieveGeneratedKeys=true. Then the generated keys will be provided as headers with the keys listed in the table above.

You can see more details in this unit test.

Using generated keys does not work with together with named parameters.

Using named parameters

Available as of Camel 2.12

In the given route below, we want to get all the projects from the projects table. Notice the SQL query has 2 named parameters, :?lic and :?min.
Camel will then lookup these parameters from the message headers. Notice in the example above we set two headers with constant value
for the named parameters:
