我试过SQL的程序,如果产生新表table2,就不会出现warning,字段a也改了属性,与data步不一样,这应该是由于data和SQL的产生数据集的一原理不同吧。
Proc SQL;
create table table2 as
select input(a, comma6.) as a
from table1;
quit;
hello!
did you wake up to the value 10 of variable a in table1 has been changed to 0.1 through by input function?
any improved way to avoid this error?
