@@ -81,6 +81,33 @@ The `value` in each parameter expression can be any valid SpEL expression.
The `#root` object for the expression evaluation is the constructor argument defined on the `parameterSource` bean.
It is static for all evaluations (in this case, an empty String).
Starting with _version 5.0_, you can use pass parameter types using `setSqlParameterTypes` method in
the `ExpressionEvaluatingSqlParameterSourceFactory` can be supplied with the sqlParameterTypes to specify the target SQL type for the particular parameter.
Below example provides sql type for the parameters being used in the query.

<int-jdbc:inbound-channel-adapter query="select * from item where status=:status"
channel="target" data-source="dataSource"
select-sql-parameter-source="parameterSource" />
<bean id="parameterSource" factory-bean="parameterSourceFactory"
factory-method="createParameterSourceNoCache">
<constructor-arg value="" />
</bean>
<bean id="parameterSourceFactory"
class="o.s.integration.jdbc.ExpressionEvaluatingSqlParameterSourceFactory">
<property name="sqlParameterTypes">
<map>
<entry key="status" value=""#{ T(java.sql.Types).BINARY}" />
</map>
</property>
</bean>
----
IMPORTANT: Use the `createParameterSourceNoCache` factory method; otherwise the parameter source will cache the result of the evaluation.
Also note that, because caching is disabled, if the same parameter name appears in the select query multiple times, it will be re-evaluated for each occurrence.
