Please help with this tabulation

HI,

I have got this sort of data:

student ID booksborrowed

111 3

111 4

111 1

123 4

123 1

124 4

125 2

Now I want to find the total i.e summary of books borrowed for each student ID for example.

student ID Total booksborrowed

111 8

123 5

124 4

125 2

Many thanks in advance.

/*SQL*/

data have;

input student_ID :$ booksborrowed ;

cards;

111 3

111 4

111 1

123 4

123 1

124 4

125 2

;

proc sql;

select student_id, sum(booksborrowed) as total from have group by student_id;

quit;

/*or data step*/

data want (drop=booksborrowed);

set have;

by student_id notsorted;

total+total*(-first.student_id)+booksborrowed;

if last.student_id then output;

run;

Hi:

You did not say whether you wanted a REPORT (such as with TITLES and TOTALS, etc) or an output dataset of the summary information. In addition to the SQL and DATA step solutions already posted, SAS has several procedures that will create either reports or output datasets (or both) that would calculate total books borrowed. The procedures are: FREQ, TABULATE, REPORT, MEANS. See code below. Each procedure produces a report (shown in 1a, 2a, 3a and 4a output) and then each procedure also produces a dataset, which is printed with PROC PRINT (in 1b, 2b, 3b and 4b outputs).
