SAS %INCLUDE 语句 - 即使出现错误也继续

Question

我有一个代码告诉我文件中出现问题 a.sas

%errmail

我在另一个文件中使用 %include 函数，但是当我在那里时：

data a;
infile "/usr/local/abc/load_file" dlm='09'x firstobs=2;
INPUT id age;
run;

PROC SORT DATA=_load_a. NODUPKEY;
 BY id;

  proc sql noprint;
delete from abc.my_table;
quit;

proc append BASE=abc.my_table; DATA=load_a. FORCE; 

%include "/usr/local/abc/a.sas";

如果此处出现错误（在 %include 函数之前），那么我不会收到电子邮件。如果我想获取有关此函数之前的错误的信息，我可以使用 %include 函数吗？

下面是log的一部分，所以我之前出错了，include函数的部分没有做。

Answer 1

您的 proc append 中有一个额外的半列：

 proc append BASE=abc.my_table; DATA=load_a. FORCE;

应该是：

 proc append BASE=abc.my_table DATA=load_a. FORCE;

Answer 2

请注意，&SYSERR 变量在每一步后都会重置，如所写，这只会检测紧接在 %INCLUDE 语句之前的 PROC APPEND 步骤是否发生错误。

也就是说，如日志中所示，如果 PROC APPEND 错误，它可能会使 SAS 进入 SYNTAXCHECK 模式。请参阅 SAS 设置选项 obs=0 的注释。在这种状态下，没有代码被执行，SAS 只是检查代码是否存在编译错误。

如果您想从 SYNTAXCHECK 模式中恢复，以便 SAS 继续执行错误后发生的代码，您可以在 data _null_ 步骤之前将以下 OPTIONS 语句添加到您的 %ERRMAIL 宏中：

options obs=max replace nosyntaxcheck;

SAS %INCLUDE 语句 - 即使出现错误也继续

SAS %INCLUDE Statement - proceed even if an error
