Merging with Many to Few

jl1005 — Thu, 30 Mar 2017 16:56:37 GMT

Hi everyone,

I'm trying to merge two data sets together to use in creating a calculated field. Here's the code for the sorting and merging:

proc sort data=all_batting out=sorted_all;
	by descending year_id;
	run;
proc sort data=bat_weights out=sorted_bat_weights;
	where season between 1981 and 2015;
	by descending season;
	run;
data all_with_weights;
	merge sorted_all sorted_bat_weights (rename=(season=year_id));
	by year_id;
	run;

Here's the error: ERROR: BY variables are not properly sorted on data set WORK.SORTED_BAT_WEIGHTS.

Here are pictures of what each sorted data set looks like:

The sorted_all table contains multiple records for each year, where as the bat_weights only has one row per year. I'm not too sure what's going wrong.

Thank you,

Justin

You are not sorting by the same desired by variable for both sets in your merge.

Isn't that what the rename is doing in the data step? It's renaming season to year_id so that they are the same variable names.

Oh. I did not look closely enough. What does your log say? Is there an error or are you just not seeing what you expect.

Other than the "by variables" error, that is. I'm wondering if something else is happening upstream.

You sort descending, but then merge by year_id NOT descending.
