numeric datetime to character

[JillChen0131]

I have a numeric version of datetime, like13DEC2021:10:28:00. I would like to convert it to character format like yyyy-mm-dd:hh:mm. Thanks for your help

Why character? Teradata load?

Otherwise I typically recommend the ISO format.

proc format;
picture dtpic
other='%Y-%0m-%0d %0H:%0M:%0S' (datatype=datetime)
;
run;

data a;
 a = datetime();
length b $30.;
 b = put(a, dtpic.);
 format a dtpic.;
run;
