请教问题,关于SAS中proc sql的使用
proc sql outobs=14;
select *,loga*photo as logphoto format 8.2,
(calculated logphoto*frienda) as lpf from shuju4
where age not in(12,13,14)
order by loga;
quit;
proc sql;
select count(loga) as loga_count from shuju4;
quit;
不止这些,我在写 proc sql中老是会出现报错信息,信息如下:ERROR: Utility file open failed.
什么意思?如何解决 呢?
