mybatis传输日期字符串sql诡异报错

Posted 2023-02-07 Arvin_Wong

sqlserver+mybatis

sql：

	 SELECT SODD.ITEM_ID
		,DATEDIFF(MM,SOD.DOC_DATE,'2019-04-24') AS MONTH_DIFF 
		,SUM(SODD.BUSINESS_QTY) 下单数量
	 FROM SALES_ORDER_DOC SOD
	 LEFT JOIN SALES_ORDER_DOC_D SODD ON SOD.SALES_ORDER_DOC_ID=SODD.SALES_ORDER_DOC_ID
	 WHERE SOD.ApproveStatus='Y' AND DATEDIFF(MM,SOD.DOC_DATE,'2019-04-24')<6 
	 GROUP BY SODD.ITEM_ID,DATEDIFF(MM,SOD.DOC_DATE,'2019-04-24')

sqlserver中运行sql没有问题

但是在mybatis中：

    List<ProductScheduleDTO> productSchedule(@Param("deadLine") String deadLine,@Param("belong") String belong);

    <select id="productSchedule" parameterType="string" resultMap="productScheduleMap">
        SELECT SODD.ITEM_ID
            ,DATEDIFF(MM,SOD.DOC_DATE,#deadLine) AS MONTH_DIFF
            ,SUM(SODD.BUSINESS_QTY) 下单数量
        FROM SALES_ORDER_DOC SOD
        LEFT JOIN SALES_ORDER_DOC_D SODD ON SOD.SALES_ORDER_DOC_ID=SODD.SALES_ORDER_DOC_ID
        WHERE SOD.ApproveStatus='Y' AND DATEDIFF(MM,SOD.DOC_DATE,#deadLine)&lt;6
        GROUP BY SODD.ITEM_ID,DATEDIFF(MM,SOD.DOC_DATE,#deadLine )
    </select>

他就报错：

然后我复制了idea插件mybatis sql log日志工具中的sql到编译工具中执行，没毛病

到底哪里有问题啊。。。。。。

 

第二天。。解决了

把gourp by放在外层，第一次只做datediff获得月份差值，第二层再group by就搞定了

还是十分疑惑为什么，这或许是在提醒我该看源码了
