如何在 Crystal Reports 中将 DateTime 对象转换为字符串 [英] How to convert DateTime object to string in Crystal Reports

问题描述

我在下面有一行简单的 Crystal Reports 代码:

I have a simple line of Crystal Reports code below:

EffectiveDateTimeString = ToText({Command.EffectiveDate} , "dd-MM-yyyy hh:mm:ss" );

但是，当我尝试验证公式时，我收到一条错误消息，提示已为此函数提供了太多参数"并选择了dd-MM-yyyy hh:mm:ss".Command.EffectiveDate 是 DateTime 对象.如何将其转换为字符串?

However, when I try to validate the formula, I get a error saying "Too many arguments have been given to this function" with "dd-MM-yyyy hh:mm:ss" selected. Command.EffectiveDate is the DateTime object. How can I convert this to a string?

谢谢！

推荐答案

你需要使用赋值运算符:=，而不是等价的=:

You need to use the assignment operator :=, not the equivalency one =:

EffectiveDateTimeString := ToText({Command.EffectiveDate} , "dd-MM-yyyy hh:mm:ss" );

*编辑 *

此代码段按预期工作:

ToText(CurrentDate + CurrentTime, "dd-MM-yyyy hh:mm:ss");

确保您的字段实际上返回的是日期/时间，而不是其中一个.

Ensure that your field is actually returning a date/time, rather than one or the other.
