Hash merge

[mauri0623]

I have merged two table together for the purpose of table lookup. I want the pips dataset to lookup the dai_fixed dataset for the variables task_number, loa, and tas. The code does that. What else I want the code to do is if it find the match I want it to place it in a pips_dai_match and if not place it in another dataset called error. Below is the code.

data PIPS_DAI_Match(drop=rc);

if 0 then set work.dai_fixed;

if _N_ = 1 then do;

declare hash h(dataset:'work.dai_fixed');

h.defineKey('project_number');

h.defineData('task_number', 'loa', 'tas');

h.defineDone();

call missing(task_number, loa, tas);

end;

set pips;

rc=h.find();

run;

A small correction will give you what you want

data PIPS_DAI_Match error(drop=rc);
if 0 then set work.dai_fixed;
if _N_ = 1 then do;
declare hash h(dataset:'work.dai_fixed');
h.defineKey('project_number');
h.defineData('task_number', 'loa', 'tas');
h.defineDone();
call missing(task_number, loa, tas);
end;

set pips;

if h.find()=0 then output PIPS_DAI_Match;
else output error

run;
