我想寫JdbcPagingItemReader與像一個複雜的查詢:JdbcPagingItemReader具有多個選擇查詢
從YYY選擇XXX,其中a = b和c =(從(F)YYY其中A = B選擇最大)
...帶參數。
這裏是我寫我的查詢:
<bean
class="org.springframework.batch.item.database.support.SqlPagingQueryProviderFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="selectClause" value="SELECT ohrefnum" />
<property name="fromClause" value="FROM orderhdr_all" />
<property name="whereClause"
value="WHERE customer_id =: CUSTOMER_ID AND ohentdate = (SELECT MAX (ohentdate) FROM orderhdr_all WHERE customer_id =: CUSTOMER_ID)" />
<property name="sortKey" value="ohrefnum" />
</bean>
,但它引發以下錯誤:java.sql.SQLException: Missing IN or OUT parameter at index:: 2
