How to use SYSERR in macro as e-mail trigger if error during query to Teradata

Hello,

Long story short. In my company is a migration from old server to new one. Good oportunity to deepedive into old code and make some upgrades. So i try do some easy notyfication about errors during calculation and I have some problems.

Idea is as following.

Add to every sas code scheduled on server one macro execution line

%codeEndStatus(e-mail title,&SYSERR.);

This leads to macro program

%macro codeEndStatus(codeName,error);
%include "&commonsPath./emailAuth.sas"; /*data necessary to send e-mails*/

%if &error. = 0 %then %do ;
OPTIONS LINESIZE=256;
FILENAME output EMAIL SUBJECT= "#OK &codeName. OK"
FROM= e@mail.com
TO=e@mail.com
attach=("&logSpace./&curentProgramName._&todayShort..log")
CT= "text/html";* Required for HTML output;

ODS HTML BODY=output STYLE=noBorder;
proc odstext;
p "Everything is fine";
run;
ODS HTML CLOSE;

%end;
%else %do;
OPTIONS LINESIZE=256;
FILENAME output EMAIL SUBJECT= "#Error &codeName. "
FROM= e@mail.com
TO= e@mail.com
attach=("&logSpace./&curentProgramName._&todayShort..log")
CT= "text/html";* Required for HTML output;

ODS HTML BODY=output STYLE=noBorder;
proc odstext;
p "Something went wrong, check log file";
run;
ODS HTML CLOSE;

%end;

%mend;

And. Everything is fine except this situation (most common in my work).

If errors occur during selecting data from Teradata or Hadoop dataset, from SAS point of view It`s no error. Everything fine. Naturally output file is empty.

Yes, usualy empty file provide errors during next computing. But not in my case, becouse I select only recent record from Teradata and append it with existing in SAS serwer dataset.

So I looking for a solution. Maybe it`s another variable to use?

First thing I invented it`s simply check number of record in new table and stop executing if it's null. But I have a lot of query to external sources in my code, so adding few lines after every query is a monkey job.

Have you tried using &syscc instead of &syserr?

I was going to recommend that you check that the tables are not empty, but it sounds like you've already considered that.

Do you call your %codeEndStatus macro after each table you query? If you're only considered about a small number of the tables being empty, you could add an additional parameter indicating that you should check the number of records. You could do this inside your %codeEndStatus macro, and set the default to false so that you don't have to change your logic for all your other jobs. Is my understanding correct?

PS it is easier to have the scheduler react to the overall return code of a SAS program and send mails.

I call macro at the end of code. So after every query.
