Ho due macro sotto che sto cercando di eseguire 1 dopo l'altro come un loop utilizzando una tabella di metadati e il comando di esecuzione della chiamata in un passo di dati.Problema di variabili macro quando si utilizza la chiamata execute
macro% TWO richiede la variabile globale & names_agg. che dovrebbe essere creato nella macro% ONE. Tuttavia, nel codice seguente, & names_agg è vuoto la prima volta che lo eseguo. Se lo eseguo di nuovo, manterrà solo il valore dall'ultima volta che viene eseguito.
L'idea è che ogni volta che viene eseguito% ONE, un nuovo & names_agg. è creato.
Cosa sto sbagliando?
Grazie
%macro ONE(condition);
%global names_agg;
%let names_agg = ;
proc sql;
select
cats(name,"_agg"),
into
:names_agg separated by " ",
from dataset
where condition = "&condition."
;
quit;
%mend;
%macro TWO(name_OT);
data &name_OT.;
set &names_agg.;
run;
%mend;
data _null_;
length code $32767;
set meta_table;
code = "%ONE(" || cats(condition) || "); %TWO(" || cats(Name_OT) || ");";
call execute(code);
run;
Mi dispiace per il registro disordinato, questo è il codice vero e proprio. Il problema è con NAMES_AGG_A _B e _C non risolvendo correttamente
