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.

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.

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

Astounding
PROC Star

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;

I have attached XLS file. Pls have a look on attached file and replay to me.

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): real time 0.15 seconds cpu time 0.01 seconds

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.

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.

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.
