Dataset Proc数据集在一个步骤中修改多个数据集

sas

Dataset Proc数据集在一个步骤中修改多个数据集,dataset,sas,Dataset,Sas,我使用以下方法从数据集中删除标签： proc datasets lib=my_lib memtype=data nolist ; modify my_data_1 ; attrib _all_ label=' '; run; quit; 我想为几个数据集做这个，我的数据集，…，我的数据集。使用以下命令将返回错误（应为；，/）：我想知道是否有一种方法可以将例外应用于以下情况： proc datasets lib=my_lib memtype=data nolist ;

我使用以下方法从数据集中删除标签：

proc datasets lib=my_lib memtype=data nolist ;
   modify my_data_1 ; 
     attrib _all_ label=' '; 
run;
quit;

我想为几个数据集做这个，我的数据集，…，我的数据集。使用以下命令将返回错误（应为；，/）：

我想知道是否有一种方法可以将例外应用于以下情况：

proc datasets lib=my_lib memtype=data nolist ;
   modify _all_ ;        
   attrib _all_ label=' '; 
run;
quit;

我要修改的数据集占大多数，这将更加有效。

更简单的方法是使用复制和选择，例如：

proc datasets ;
copy in=sashelp out=work;
select cars baseball;
attrib _all_ label=' ';
run;

这里的另一种方法是构造对

proc数据集的单个调用

，该调用将使用多个

运行一次完成所有操作进程内的组。目标是构建如下内容：
data example1 example2;
    set sashelp.class;
    label sex = 'example label';
run;

proc datasets lib = work nolist;
    modify example1;
    attrib _all_ label = '';
    run;
    modify example2;
    attrib _all_ label = '';
    run;    
quit;

这可以通过一个相当简单的宏循环或带有调用执行的数据步骤实现，例如
data _null_;
    set sashelp.vtable end = eof;
    where libname = 'WORK' and memtype = 'DATA' and memname eq: 'EXAMPLE';
    if _n_ = 1  then call execute('proc datasets lib = work nolist nodetails;');    
                     call execute(catx(' ','modify',memname,'; attrib _all_ label = ""; run;'));
    if eof      then call execute('quit;');
run;

编写宏do循环是否有帮助？编写宏do循环是否有帮助？是否可以使用此方法复制到同一个库中？是的。如果语法正确proc datasets lib=my_lib；复制选择“我的数据”：；属性标签=''；运行冒号是通配符。这比我对小数据集的回答要好。对于大型数据集，这太耗时了，因为您不仅要编辑数据集的元数据，还要复制完整的内容。是否可以使用此方法复制到同一个库中？是的。如果语法正确proc datasets lib=my_lib；复制选择“我的数据”：；属性标签=''；运行冒号是通配符。这比我对小数据集的回答要好。对于大型数据集，这太耗时了，因为您不仅要编辑数据集的元数据，还要复制完整的内容。
