cognos - Need help building a Data Item in Cognos Report Studio

Question

So I have a table with employee name, job and shift. Each employee (Row) has a unique name, a non unique job and one of 4 shifts (A, B, ,C or D). I want to create a Data Item called "Shift A Employees" that that for each job it spits out one string that contains all the employees who work that ob on that shift for example:

I have this

And want to be able to have this

How would I go about writing my expression definition for my "Shift A Employees" data item?

创建一个执行此操作的数据项可能相当复杂。为什么不将中继器表拖到您的列表中？您需要向查询中添加两个数据项。一个是running-count(1 for [Job])（我想。我现在没有我的例子。）另一个将该值与工作的最大值进行比较。如果值匹配，则不返回任何内容，如果不匹配，则返回逗号。这是模式：

case
when [rownum] < [maxrownum] then ','
else ''
end

命名它comma。然后，您只需将 [Name] 和 [comma] 拖到中继器表中。使中继器表高 1 行，列宽比您认为需要的多。您需要为转发器表定义主从关系。
