how to get the third table based on the two?

Hello,

I have two tables year2015, year2016, but how can I get the third table ds1 based on the two by coding sas? Thanks!

data year2015;
input year $ resp ;
datalines;
null 0.35
s_300 0.55
s_640 0.65
s_670 0.75
s_700 0.47
s_730 0.58
s_760 0.69
;run;
data year2016;
input year $ resp ;
datalines;
null 0.45
s_300 0.65
s_640 0.42
s_670 0.35
s_700 0.83
s_730 0.48
s_760 0.69
;run;

data ds1;
input year $ mid $ resp exp rev;
datalines;
null d_2016 0.45 0.45 0.35
null d_2015 0.35 0.45 0.35
s_300 d_2016 0.65 0.65 0.55
s_300 d_2015 0.55 0.65 0.55
s_640 d_2016 0.42 0.42 0.65
s_640 d_2015 0.65 0.42 0.65
s_670 d_2016 0.35 0.35 0.75
s_670 d_2015 0.75 0.35 0.75
s_700 d_2016 0.83 0.83 0.47
s_700 d_2015 0.47 0.83 0.47
s_730 d_2016 0.48 0.48 0.58
s_730 d_2015 0.58 0.48 0.58
s_760 d_2016 0.67 0.67 0.69
s_760 d_2015 0.69 0.67 0.69

Ok...what's the relationship between the tables...

That depends. Where do EXP and REV come from if they're not part of the incoming data sets?

there is no EXP and REV, I have to hard code it.

OK, let's ignore REV and EXP since you will be hard-coding them. Sort the data sets first, if they are not already sorted:

proc sort data=year2015;

by year;

run;

proc sort data=year2016;

by year;

run;

Then combine them:

data want;

set year2016 (in=from2016) year2015 (in=from2015);

by year;

if from2016 then mid='d_2016';

else mid='d_2015';

run;

And another way to get something similar. Mid has the data set names here but could be modified with string functions to get D_XXXX if that format is explicitly required.

data want;
   set year2015 year2016 indsname=name;
   mid=name;
run;

proc sort data=want; 
   by year mid;
run;
