来看看 sas ods output问题-经管之家官网！

ods output ParameterEstimates=in1.ParameterEstimates&i.;
我用ods output的方法输出Logistic回归分析的结果。
循环六次得出六个数据集 ，然后我想从随便一个数据集中取出数据，
proc sql;
create table a as
select DF from in1.ParameterEstimates1
;
quit;
proc print data=a;run;
运行没有任何报错，但是不管怎样都出不了数据,也就是print不出东西LOG如下 ：
560proc sql;
561create table a as
562select DF from in1.ParameterEstimates1
563;
NOTE: Compression was disabled for data set WORK.A because compression overhead would increase the
size of the data set.
NOTE: Table WORK.A created, with 7 rows and 1 columns.
564quit;
NOTE: PROCEDURE SQL used (Total process time):
real time 0.10 seconds
cpu time 0.06 seconds
565proc print data=a;run;
NOTE: There were 7 observations read from the data set WORK.A.
NOTE: PROCEDURE PRINT used (Total process time):
real time 0.01 seconds
cpu time 0.01 seconds
这是什么原因？ 之前好像运行的时候有一个
WARNING: Data too long for column "VAR1"; truncated to 96 characters to fit.
这个问题应该怎么解决呢？我用proc contents想看下，也是没有报错，但是不出任何东西……
SAS 内部产生数据集里面有数据……
