Question

我正在尝试构建高级的报告和日志记录系统，但是我遇到了问题。

示例：

work.check_true为空。

此表为空时，则变量'czy_wyslac'应该具有值2。如果该表不为空，则变量'czy_wyslac'应该具有表work.check_true中字段“ gen”（1或0）中的值。下一步-根据变量'czy_wyslac'的值处理从三步到下一宏的操作。我对此没有问题。

下面是我的代码：

data _null_;
call symput('obscnt',0);
set work.Check_true;
call symput('obscnt',_n_);
stop;
run;

%macro get_table_size();
%global czy_wyslac;
%If &obscnt=0 %then call SYMPUTX('czy_wyslac',2);

%else
    proc sql noprint;
    select
        gen into: czy_wyslac
    from work.Check_true
    ;quit;
%mend;


%macro Create_log_mail();

   %if &czy_wyslac. = 1 %then
    %do;
        data work.maile;
        zal = "T:\XXX\XXX\Risk\XXXX\XXXX\OUTPUT\Results_of_compare &calosc..xlsx";
        run;

        options emailsys=XXemail host=XXXemailport=XXX;

        FILENAME mail EMAIL;

        DATA _NULL_;
        SET WORK.maile END=eof;
        FILE mail ENCODING='UTF-8';
        PUT '!EM_TO! "XXXXX@XXXXXX"';
        PUT 'Szanowni,';

        PUT 'Wpis _TYPE> = PLIK - baza porównywana';

Answer 1

如果work.check为空，则select gen into :czy_wyslac from work.check_true将不返回任何内容，从而保留&CZY_WYSLAC中的所有先前值。

因此，以下内容将满足您的要求：

%LET CZY_WYSLAC = 2 ; /* default value */
proc sql noprint ;
  select gen into :CZY_WYSLAC from work.check_true ;
quit ;

多个设置为宏变量
