Dynamic SQL in JdbcCursorItemReader

[MmarcoM]

Hello all
i was wondering if i can build, for my jdbcCursorItemReader, a sql like this .
Assuming i defined in my jobParameters a parameter name

<bean id="itemReader" scope="step"
        class="org.springframework.batch.item.database.JdbcCursorItemReader">
        <beans:property name="dataSource" ref="appDataSource" />
        <beans:property name="rowMapper">
            <beans:bean
                class="org.springframework.jdbc.core.ColumnMapRowMapper" />
        </beans:property>
	<property name="sql" value="select * from #{jobParameters['tableName']}"/>
....
</bean>

reason of that is that i have to configure potentially multiple jobs which export data from database tables, and all of them
will have to do a select * from <tablename>

I know i could put the whole sql as JobParameter, but all the sql will be select * from <tablename>

has anyone a better suggestion?

w/kindest regards
marco

You could go for properties file instead of passing it as jobparam

please take a look into the API of the JdbcCursorItemReader

(...)PreparedStatementSetter to use if any parameter values that need to be set in the supplied query.

so you can for sure use a custom PreparedStatementSetter Spring Bean with an attribute tableName, this attribute can be set with the jobParameters mechanism, don't forget to make the bean stepscoped
