如何在join语句中从sql中选择多个变量？

Question

proc sql noprint;
    create table Final as
    select a.*, b.(more than one variable)
    from Table as a left join cool as b
    on a.xx = b.yy
    ;
quit;

Answer 1

只需列出它们：

select a.*, b.column1, b.column2, b.column3...

Answer 2

proc sql noprint;
    create table Final as
    select a.*, b.variable1, b.variable2, [...], b.variableN
    from Table as a left join cool as b
    on a.xx = b.yy
    ;
quit;
