|| 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|http://java.sun.com/j2se/1.5.0/docs/api/java/sql/Statement.html] 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:* Camel will set the autoCommit on the JDBC connection to be false, commit the change after executed the statement and reset the autoCommit flag of the connection at the end, if the resetAutoCommit is true. If the JDBC connection doesn't support to reset the autoCommit flag, you can set the resetAutoCommit flag to be false, and Camel will not try to reset the autoCommit flag.|
| {{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 placeholders, 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 2.14* 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"}}. |
