我需要删除STARTED:/和TIME:/ 03:12,并且只显示字符串的日期部分: 03/23/1983



感谢

解决方案

Crystal Reports帮助文件是您的朋友,应该是您对内置函数和数据类型的简单问题的第一站。



在CR字符串中只是存储为字符数组所以你可以访问它们像数组 - 按索引。所以在你的情况下,如果你总是有相同的字符串格式(也就是相同的字符数,前导零等),那么你可以这样做:

  local stringvar mystr:= {table.your_string}; // mystr:=STARTED:/ 03/23/1983 TIME:/ 03:12
mystr [11 to 20] // return03/23/1983
pre>

或者,您可以使用Mid()字符串函数。


I'm trying to only show the date portion of a string field. This is the format of the string: STARTED:/ 03/23/1983 TIME:/ 03:12

I need to remove "STARTED:/" and "TIME:/ 03:12" and only show the date portion of the string:03/23/1983. What formula can I use to do that?

Thanks

解决方案

The Crystal Reports help file is your friend and should be your first stop for simple questions on built-in functions and data types.

In CR strings are just stored as character arrays so you can access them like arrays - by index. So in your case, if you will always have the same string format (that is, the same number of characters, leading zeroes, etc.) then you can do something like this:

local stringvar mystr := {table.your_string}; //mystr:="STARTED:/ 03/23/1983 TIME:/ 03:12"
mystr[11 to 20] //return "03/23/1983"

Alternatively, you could use the Mid() string function.
