栏位索引超过许可范围:1,栏位数:0。; nested exception is org.postgresql.util.PSQLException: 栏位索引超过许可范围:1,栏位数:0。

在开发的过程中遇到这个问题,真的很痛苦,网上说的各种做法我都试了一遍,但是都不好使。分页情况遇到的。

无奈之下,只能投机取巧了,修改后的mapper.xml文件如下:

 <select id="queryItemPage" resultMap="reBranch"
            parameterType="com.picc.hfms.budget.dto.BrBudgetItem">
        select * from (
        select row_number()over(partition by item_id order by audit_date desc )rn, test.* from (
        select a.item_id,
        a.budget_id,
        a.item_code,
        a.item_name,
        a.total_amount,
        a.org_code,
        a.item_type,
        a.service_type,
        a.is_hairpin,
        a.hairpin_num,
        a.product_code,
        a.product_name,
        a.service_code,
        a.service_name,
        a.remark,
        a.insert_oper,
        a.insert_time,
        a.update_time,
        a.update_oper,
        b.budget_code,
        b.budget_name,
        b.actual_total_amount,
        c.status,
        c.audit_date,
        c.item_trace_id
        from t_budget_item_branch  a
        join  T_BUDGET_ITEM_BRANCH_TRACE c on a.item_id=c.item_id
        left   join  T_BUDGET_BRANCH b on a.budget_id=b.budget_id
        )  test  ) aaa where rn='1'
        <if test="Status!=null and Status != ''">
            and status like #{Status}
        </if>
        <if test="itemName!=null and itemName != ''">
            and item_name like #{itemName}
        </if>
        <if test="itemCode!=null and itemCode != ''">
            and item_code like #{itemCode}
        </if>
        <if test="isHairpin!=null and isHairpin != ''">
            and is_hairpin like #{isHairpin}
        </if>
        <if test="budgetId!=null and budgetId != ''">
            and budget_id = cast(#{budgetId} as NUMERIC )
        </if>
        <if test="orgCode!=null and orgCode != ''">
            and org_code like #{orgCode}
        </if>
        <if test="itemType!=null and itemType != ''">
            and item_type like #{itemType}
        </if>
        <if test="itemId!=null and itemId != ''">
            and item_id = cast(#{itemId} as NUMERIC )
        </if>
        <if test="itemName!=null and itemName != ''">
            and item_name like #{itemName}
        </if>
        order by update_time desc
        offset (#{page}- 1)* #{limit} limit #{limit}  手动分页
    </select>
Dao层原来的写法
Page<BranchVo> brL = branchBudgetDao.queryItemPage(pageParam,brBudgetItem);
Dao层改变后的写法
Page<BranchVo> brL = branchBudgetDao.queryItemPage(brBudgetItem);//不传分页参数,分页参数,放到BrBudgetItem实体类中,添加相应的分页属性,limit-页大小   page起始页码
经过修改,就好使了。
总结:传pageparam的时候,mapper.xml文件中查询的单表,所以没有问题,但是现在查询的是多表,所以这样写可能就不行,所以要换一种写法。仅个人愚见。
