Solved: Re: SAS macro variable not getting resolved

Filipvdr · Posted 01-17-2020 08:00 AM

Hello, i'm trying to write a macro to reload all my tables into LASR from HADOOP.

I'm struggling with the following:

Tablelist is a table which has all the tables which are in my metadata.

I'm checking if the table in hadoop, is also still present in lasr. The result should be in to_be_loaded.

I'm sure there is a table "TABEL_A_TEST" in library CO1IT01L. But the macro variable to_be_loaded never gets resolved in my next step %if &to_be_loaded > 0 %then ...

Where is my mistake?

%macro test;
proc sql noprint;
	 select count(*) into :to_be_loaded from tablelist
	 where upcase(libref)=upcase("co1it01l") and upcase(table_name) = upcase("TABEL_A_TEST");
	run;
	quit;
%put &table exists in metadata (1/0): &to_be_loaded; 

 %if &to_be_loaded > 0 %then %do;
    LIBNAME co1it01l SASIOLA  TAG=co1it01h  PORT=10011 HOST="sasva1.al.ndis.be"  SIGNER="https://sas.test.be:443/SASLASRAuthorization" ;
	    %if %sysfunc(exist(co1it01l.TABEL_A_TEST)) %then %do;
	       %PUT ALREADY LOADED: co1it01l.TABEL_A_TEST;
	    %end;
	    %else %do;
		 proc lasr port=10011 data=co1it01h.TABEL_A_TEST add noclass
	            signer="https://sas.test.be:443/SASLASRAuthorization";
	            performance host="sasva1.al.ndis.be";
	        run;
	        %PUT RELOADED: co1it01l.TABEL_A_TEST;
	    %end;
 %end;
 %else %do;
 %PUT NOPE;
 %end;
%mend;
%test;

There is a timing issue if you use CALL EXECUTE() to invoke a macro.

The first issue is that if you use double quotes in the CALL EXECUTE() statement

call execute("%mymacro()");

the macro will be evaluated before the data step runs and the generated code will be included as constant text. Using single quotes will prevent the macro processor from evaluating the macro expressions.

call execute('%mymacro()');

But the second issue is a little harder to see. SAS will evaluate the macro expression while CALL EXECUTE() is passing the string to the stack to run after the current data step finishes. For simple macros this does not cause a problem (other than making a very ugly SAS log). But for a macro that changes the values of macro variables using SAS code (call symputx() calls or INTO clause in PROC SQL) and then tries to use those changed values in macro logic you have a problem. The decision about what code to generate is made BEFORE the code that sets the macro variable has had a chance to run.

That is why %NRSTR() helps. It prevents the macro from running while CALL EXECUTE() is running. Instead the call to the macro is pushed onto the stack. And the SAS log also looks nicer since it will just show the macro call instead of all of the statements the macro generates.

call execute('%nrstr(%mymacro)()');

Hi @Filipvdr

The first part of the code seems to work.

Are you sure there no typo, i.e. TABLE_A_TEST instead of TABEL_A_TEST for example?

Could you please share a sample of input data WORK.TABLELIST with the two variables LIBREF and TABLE_NAME ? (Maybe there is a truncation of data or leading/trailing blanks?)

To get more information, place this command at the start of the program, and then re-run the program. This writes very useful diagnostic information to the LOG.

options mprint mlogic symbolgen;

If you can't figure out what the problem is, then SHOW US the log by pasting it into the window that appears when you click on the {i} icon.

Ok here is my full code and log.

Im trying to write a script which loads everything which is available in HADOOP libraries to LASR, if the metadata is still present of the LASR table.

Problem is when i'm checking in the tablelist if the table is still present, the macrovariable to_be_loaded does not seems to getting filled/resolved.

options mprint mlogic symbolgen;

Adding the %nrstr solved it apparently..

Tom · Posted 01-17-2020 08:49 AM

There is a timing issue if you use CALL EXECUTE() to invoke a macro.

The first issue is that if you use double quotes in the CALL EXECUTE() statement

call execute("%mymacro()");

the macro will be evaluated before the data step runs and the generated code will be included as constant text. Using single quotes will prevent the macro processor from evaluating the macro expressions.

call execute('%mymacro()');

But the second issue is a little harder to see. SAS will evaluate the macro expression while CALL EXECUTE() is passing the string to the stack to run after the current data step finishes. For simple macros this does not cause a problem (other than making a very ugly SAS log). But for a macro that changes the values of macro variables using SAS code (call symputx() calls or INTO clause in PROC SQL) and then tries to use those changed values in macro logic you have a problem. The decision about what code to generate is made BEFORE the code that sets the macro variable has had a chance to run.

That is why %NRSTR() helps. It prevents the macro from running while CALL EXECUTE() is running. Instead the call to the macro is pushed onto the stack. And the SAS log also looks nicer since it will just show the macro call instead of all of the statements the macro generates.

call execute('%nrstr(%mymacro)()');

Hi,

I suspect this is a CALL EXECUTE timing problem.

When CALL EXECUTE executes code that uses data to generate macro variables, the timing is tricky. Your macro:

%macro LoopLibraries(HDFSLIBRARY);
    LIBNAME &HDFSLIBRARY. SASHDAT  PATH="/&HDFSLIBRARY."  SERVER="svfl-app-p021.ndis.be"  INSTALL="/opt/sas/int/TKGrid" ;

    proc contents data=&HDFSLIBRARY.._all_ out=datasets noprint;
    run;

    proc sort nodupkey data=datasets; by libname memname; run;

    data looplibraries;
        set datasets;
        lasrlib = strip(substr(libname,1,length(libname)-1)) || "L";
		if memname = "TABEL_A_TEST";
        call execute('%ReloadTable('||strip(libname)||','||strip(memname)||','||strip(lasrlib)||');');
    run;
%mend;

Uses CALL EXECUTE to invoke %RELOADTABLE. It will immediately execute %RELOADTABLE and generate a bunch of SAS code and write it to the input stack. But all of that code is written to the input stack before

proc sql ;
	 select count(*) into :to_be_loaded from tablelist

has executed, so &to_be_loaded is not what you expect.

To avoid this problem, you can add %NRSTR() to your call execute:

call execute('%nrstr(%ReloadTable('||strip(libname)||','||strip(memname)||','||strip(lasrlib)||'))');

This will allow call execute to place the macro call on the input stack, rather than execute the macro.

It allows the timing to work out, and also makes the log cleaner, because you see the macro call generated by call execute.

For more explanation of this CALL EXECUTE timing issue, see e.g. https://blogs.sas.com/content/sgf/2017/08/02/call-execute-for-sas-data-driven-programming/
