Crystal Reports SELECT CASE 语句 [英] Crystal Reports SELECT CASE statement

问题描述

我在 Crystal Report 中有一个如下所示的 switch 语句:

I have a switch statement in a Crystal Report that looks like this:

stringvar tag := {table1.field1};  //contains a string value

select tag case
  'First Value': {table1.field3}
  'Second Value': {table4.field9}
  default: 'Unknown';

但是当我尝试保存公式时，我得到了这个错误:

But when I try to save the formula, I get this error:

---------------------------
Crystal Reports
---------------------------
The remaining text does not appear to be part of the formula.
---------------------------
OK   
---------------------------

在我的示例中，它突出显示了以第二"一词之前的单引号开头的公式.

And it highlights the formula beginning with the single quote before the word "Second" in my example.

我犯了什么愚蠢的语法错误?

What stupid syntax error am I making?

推荐答案

这个不应该写成...

select (tag )
  case 'First Value': {table1.field3}
  case 'Second Value': {table4.field9}
  default: 'Unknown';

?
注意，我只是在网上查看了语法；我不是 Crystal Reports 专家...

Note, I just looked the syntax online; I'm not a Crystal Reports specialist...
