Hi,

I'd like to make a calculation similar to pivot table in SAS (using Data Integration studio). My data looks like follows:

ID TYPE

1  NEW

1  NEW

1  CHURN

2  NEW

2  CHURN

3  WINBACK

I want to turn it into the following form:

ID NEW CHURN WINBACK

1   2       1             0

2   1       1             0

3   0       0             1

Can you help me with simple solution?

The SAS method for pivot tabling is proc transpose, and under the Data Transformations you'll see the Transpose transformation.

 

Here's Base code that will (mostly) do what you want:

 

data from;
infile cards firstobs=2;
attrib id length=3;
attrib type length=$ 7;
input id type;
cards;
ID TYPE
1  NEW
1  NEW
1  CHURN
2  NEW
2  CHURN
3  WINBACK
;
run;

proc sql;
create table to as
  select id,
         type,
		 count(*) as count
    from from
	group by id, 
type; quit; proc transpose data=to out=to_trans(drop=_name_); by id; id type; var count; run; option missing='0'; proc print data=to_trans noobs width=min; run;

Note that I setting missing to '0' at the end. This is because there are obviously values in the transposed dataset which don't have a value; proc print would otherwise print them as missing. If you want them as zero in the dataset, you'll have to do some post-processing.

 

So as you can see, you'll have to process your dataset twice: once to do the counts (SQL Extract transformation), then rotating it (Data Transpose).

It works! Thank you

It's a pleasure.

 

It can be tricky mapping the id columns with the transpose transformation. I find that, if I don't already know the cardinality of type, I run the job, refresh the metadata and see what's what. It all depends on what you want to do with the data afterwards.
