没有什么问题呀。你单元格的数据集重新拖一下字段呢，还有你的参数加到参数面板没有。。或者把之前的参数面板的参数删除掉，你重新加上去。参数面板上的名称要和数据集的参数名称一样

select 

year(dstartdate)as 开始时间年份,

CONVERT(varchar(10), CONVERT(date, dstartdate), 120)as 合同开始时间,

CONVERT(varchar(10), CONVERT(date, denddate), 120)as 合同结束时间,

chzmanner + Convert(varchar(10),cdefine4)  as 合作方式,

cfree1 as 合作品牌,

Zkprice as 信用额度,

ccuscode as 客户编码,

isumrate as 回款比率,
