sas中的等效date_part函数

Question

我有一个sql语句来提取日期对象.它在Postgres中运行良好,但不是sas.零件查询是这样的:

(case when date_part('month',run_date)::integer < 10 
     THEN '0'||
          date_part('month',run_date)::varchar(1)||
          date_part('year',run_date)::varchar(4)
     else  date_part('month',run_date)::varchar(2)||date_part('year',run_date)::varchar(4)
     end) as our_date

在sas中,没有date_part函数.我试过datepart函数.但它没有执行相同的功能.我怎么能在sas中运行sql语句？谢谢.

DATEPART

data have;
 timestamp='01JAN2012:08:48'dt;
run;

proc sql;
 select datepart(timestamp) format=mmddyy10., 
 timepart(timestamp) format=time.,
 month(datepart(timestamp)),
 year(datepart(timestamp))
 into :date , :time, :month, :year
 from have;
quit;

%put DATE: &date;
%put TIME: &time;
%put MONTH: &month;
%put YEAR: &year;
