Change Variable Data Type

[MrAn]

Hello everyone,

I want to change the variable type from Char to Num.

How is it possible?

PROC SQL;
CREATE TABLE WORK.query AS
SELECT Datum , Menge FROM DEMAND.DEMAND ORDER BY sortkey(Datum, "de");
RUN;
QUIT;

PROC DATASETS NOLIST NODETAILS;
CONTENTS DATA=WORK.query OUT=WORK.details;
RUN;

PROC PRINT DATA=WORK.details;
RUN;

Data  DEMAND.DEMAND;

Of what, the DATUM variable?  If so then input() is the one you want:

proc sql;
  create table QUERY as
  select  input(DATUM,yymmdd10.) as DATE,
          MENGE
  from    DEMAND.DMAND
  order by DATE;
quit;

You cannot change the type of a variable, you need to create a new variable - which is what the select as is actually doing behind the scene.
