VS 2008 报告
我正在使用 Visual Studio 2008 和 C#。 我想在我的柱形图上显示查询结果。 我的查询是：
select (select count(cinsiyeti)
from Hastalar where cinsiyeti = 'E') AS ERKEK ,
(select count(cinsiyeti) from Hastalar where cinsiyeti = 'K') AS KADIN
我获取值和数据集名称。 值： =Fields!Erkek.Value 和 =Fields!Kadin.Value
但编译器给出错误：
图表“cCinsiyeteGoreHastaSayisi”的标签表达式引用了字段“Erkek”。 报表项表达式只能引用当前数据集范围内的字段，或者如果在聚合内，则引用指定数据集范围内的字段。 C:\Users\cagin_arslan\Documents\Visual Studio 2008\Projects\RaporCalisamalari\RaporCalisamalari\rptCinsiyeteGoreHastaSayisi.rdlc RaporCalisamalari
I'm using visual studio 2008 with c#. i want to show that result of query on my column chart.
My query is:
select (select count(cinsiyeti)
from Hastalar where cinsiyeti = 'E') AS ERKEK ,
(select count(cinsiyeti) from Hastalar where cinsiyeti = 'K') AS KADIN
I get values and dataset name. values: =Fields!Erkek.Value and =Fields!Kadin.Value
but the compiler give that error:
The Label expression for the chart ‘cCinsiyeteGoreHastaSayisi’ refers to the field ‘Erkek’. Report item expressions can only refer to fields within the current data set scope or, if inside an aggregate, the specified data set scope.

只要你的变量名在数据集中的数据表中匹配并且与 sql 语句的返回值匹配就应该没问题。 正如yielvs所说，这可能是一个案例问题。
As long as your variable names match in the datatable in your dataset and with the returns of your sql statement it should be fine. Like yieldvs said it may be a case issue.
