转换ddmmyyy字符为DATE

Question

如何将ddmmyyyy形式的字符转换为DATE类型？

是否存在格式化字符变量的方法？例如，取变量的前两个字符。

Answer 1

define variable s as character no-undo initial "10092018".
define variable d as date no-undo.

d = date( integer( substring( s, 3, 2 )), integer( substring( s, 1, 2 )), integer( substring( s, 5, 4 ))).

display d format "99/99/9999".

Answer 2

DATE函数可用于此目的：

  

DATE ( month, day, year )

或

  

DATE ( string )

如果您将日期格式设置设置为dmy，则以下两项均可以使用：

define variable cDate  as character no-undo.
define variable dDate1 as date      no-undo.
define variable dDate2 as date      no-undo.

cDate  = "31122018".
dDate1 = date(cDate).
dDate2 = date (int(substring(cDate,3,2)) /*month*/,
               int(substring(cDate,1,2)) /*day*/,
               int(substring(cDate,5))   /*year*/).
display dDate1 dDate2.
