Please include what you've tried.

What part are you having difficulty with?

What at do you mean by proc step?

Also, a lot of users don't download files so consider including a sample of data in your post directly.

@Lithium-Admin, why can't I see the xlsx attachment to this message on Chrome? I get the message Error displaying attachment content.

This would be a typical approach:

proc means data=sales n sum;

var sales_amount;

where year=2010;

run;

You might have to adjust slightly, using the proper names for your variables and data set.

Too get good answers, post test data in the form of a datastep using the insert code icon - {i} - above your post. Excel files are dangerous and I would not download them. Also providing an example of what you require will get you better results. As a guess you could use proc sql:

proc sql; 
  create table WANT as
  select  YEAR, 
              sum(SALES) as TOTAL,
              count(SALES) as FREQ
  from    (select * from HAVE where YEAR=2010)
  group by YEAR;
quit;

Hi All,

This question was asked in interview to me, question is simple, interviewer asked me there is a data set, and dataset have a 4 years of sales data Exp:- 2010, 11, 12, and 13 sales data. just for a example data have 2 variable that is Date and sales, and he asked me to right a syntax to find out only 2010 total sales and total sales frequency. so can i get a solutation from any one? how to find out the answer by useing Data step and Proc step's .? I have attached XLS file. Pls have a look on attached file and replay to me.

Thank You

proc freq data = sales123;                                                                                                              
table Order_Date sales;                                                                                                                 
format Order_Date  year4.;                                                                                                              
run;

proc freq data = sales123;                                                                                                              
table Order_Date sales;                                                                                                                 
format Order_Date  year4.;                                                                                                              
run;  

by using proc freq am not getting exat answer which what i want.

80   proc print data = sales123;
81   var Order_Date sales;
82   where Order_Date = 2010;
83   run;

NOTE: No observations were selected from data set WORK.SALES123.
NOTE: There were 0 observations read from the data set WORK.SALES123.
      WHERE Order_Date=2010;
NOTE: PROCEDURE PRINT used (Total process time):

Hi,

Sorry as stated above, Excel files are not a good medium, they are unsafe. You have been provided seveal examples above. Your where clause probably (and as I can't see the data I can't say) fails as it is a date. Dates are numbers which reflect number of days since a certain timepoint, to compare this to a year value you would need to use year() function:

proc print data = sales123;
  var order_date sales;
  where year(order_date)=2010;
run;

You should really read the manual and SAS training on how to handle dates/times to understand why your where didn't work.

Note, it is the year() function.

I get that when it's not a true XLSX. I think...

If I was interviewing and the candidate claimed to know SAS but couldn't answer that question I wouldn't believe them.

Still i have not got any perfect answer for my question.

proc means data=have;
where year(date)=2010;
var sales;
output out=want1 n=Count sum=Total;
run;

proc sql;
create table want2 as
select year(date) as year, sum(sales) as Total, count(*) as Count
from have
where year(date)=2010;
quit;

Both of these solutions were already proposed.

Use the YEAR() function to extract the year from the date and get the data for 2010.

Proc Means will generate both a total and count.

Proc SQL will also generate both a total and count.

If this does not work please clearly explain what your issue is.

Hi,

To note, we do have jobs which take precedence over answering questions.

Firstly, when I ask to provide some test data, i mean 3-4 rows of data in a datastep. This is because we cannot see your data - not just the contents, but the structure as well. The logic to do this with a character field is very different to the logic used on a date column for instance. Here is an example of how to post test data:

data have;
  informat order_date ddmmyy8.;
  input Order_Date Sales;
  format order_date date9.;
datalines;
01-01-09	195.95
01-01-09	898.83
02-01-09	125.87
02-01-09	147.82
;
run;

Now lets combine this with the year() function I provided earlier on and the example where clause:

data have;
  informat order_date ddmmyy8.;
  input Order_Date Sales;
  format order_date date9.;
  yr=year(order_date);
datalines;
01-01-09	195.95
01-01-09	898.83
02-01-09	125.87
02-01-09	147.82
;
run;

proc freq data=have;                                                                                                              
  table yr sales;                                                                                                                 
  where yr=2009;
run;

Now you see in the first datastep I create a yr variable which holds the year part of the date, this both simplfies later processing and gives a variable ready for tabling. The where in the proc freq restricts the data only to year 2009.
