JdbcTemplate - SQLWarning ignored: SQL state '

Question

I am simply developing the Spring Batch partitioned code looking at http://www.mkyong.com/spring-batch/spring-batch-partitioning-example/ and already went through the link : Error Code 1292 - Truncated incorrect DOUBLE value - Mysql but it did not solved my purpose.

I have the following bean

<bean id="pagingItemReader" class="org.springframework.batch.item.database.JdbcPagingItemReader" scope="step">
        <property name="dataSource" ref="dataSource" />
        <property name="pageSize" value="200" />

        <property name="queryProvider">
            <bean class="org.springframework.batch.item.database.support.SqlPagingQueryProviderFactoryBean">
                <property name="dataSource" ref="dataSource" />
                <property name="selectClause" value="SELECT customerNumber, checkNumber,paymentDate,amount" />
                <property name="fromClause" value="FROM classicmodels.payments" />
                <property name="whereClause" value="${payments.query.where.clause}" />
                <property name="sortKey" value="customerNumber" />
            </bean>
        </property>
        <!-- Inject via the ExecutionContext in rangePartitioner -->
        <property name="parameterValues">
            <map>
                <entry key="fromId" value="stepExecutionContext[fromId]" />
                <entry key="toId" value="stepExecutionContext[toId]" />
            </map>
        </property>
        <property name="rowMapper">
            <bean class="com.prateek.mapper.PaymentsRowMapper" />
        </property>
    </bean>

Getting below error:

Answer 1

The error happens because the value stepExecutionContext[fromId] is not evaluated as a SpEL expression and goes raw (as is) to the database server.

The example you linked to uses the correct syntax: <entry key="fromId" value="#{stepExecutionContext[fromId]}" /> but in your example you have: <entry key="fromId" value="stepExecutionContext[fromId]" /> without the #{...}.

Even though the syntax in the example of mkyong is correct, I would recommend using simple quotes around keys in the execution context (<entry key="fromId" value="#{stepExecutionContext['fromId']}" />) as it is mentioned in the official documentation here: https://docs.spring.io/spring-batch/4.0.x/reference/html/step.html#late-binding
