选择全部作为多值参数的默认值 [英] Select All as default value for Multivalue parameter

问题描述

我正在Visual Studio 2008中使用大量多值参数，并且效果很好，但是我希望在打开报告时将(全选)"选项作为默认值.

I'm building a report in Visual Studio 2008 with a lot of multivalue parameters and it's working great, but I would like to have have the "(Select all)" option as the default value when the report is opened.

是否可以使用某种表达式或SQL代码来实现这一目标?还是我每次要运行报告时都需要在每个参数中每次都选择(全选)"?

Is there some kind of expression or SQL code I can use to make this happen? Or do I need to choose "(Select all)" every time, in every parameter, each time I want to run the report?

推荐答案

尝试设置参数的默认值"以使用与可用值"相同的查询.实际上，它提供了每个可用值"作为默认值"，并自动选中了全选"选项.

Try setting the parameters' "default value" to use the same query as the "available values". In effect it provides every single "available value" as a "default value" and the "Select All" option is automatically checked.
