报表生成器表达式SQL仅列出某些值

Question

In report builder i'm trying to only get the values containing 'Office' from the software list. 在报表生成器中，我试图仅从软件列表中获取包含“ Office”的值。

=Fields!Software.Value

This will get the entire list of all installed software but i want to list the values with "Office". 这将获取所有已安装软件的完整列表，但我想使用“ Office”列出这些值。

I have tried something like : 我已经尝试过类似的东西：

=Fields!Software.Value = "Office"
=IIF(Fields!Software.Value = "Office", Fields!Software.Value)

Can't seem to figure out how to achieve this. 似乎无法弄清楚该如何实现。

Answer 1

Use Filter expression: 使用过滤器表达式：

=Join(Filter(Fields!Software.Value,"Office"),",")

I added Join so you can display the list in Text Box. 我添加了加入，以便您可以在文本框中显示列表。

If you want to get particular element from the list, for example the first one, use this: 如果要从列表中获取特定元素，例如第一个元素，请使用以下命令：

=Filter(Fields!Software.Value,"Office")(0)
