我在将大型 Oracle 表转换为 SAS 数据集时遇到问题。我早些时候这样做了，并且该方法有效。但是，这一次，它给了我以下错误消息。

SAS code:

option compress = yes;
libname sasdata ".";
libname myora oracle user=scott password=tiger path=XYZDATA ;
data sasdata.expt_tabl;
   set myora.expt_tabl;
run;

Log file:

You are running SAS 9. Some SAS 8 files will be automatically converted
by the V9 engine; others are incompatible.  Please see
http://support.sas.com/rnd/migration/planning/platform/64bit.html

PROC MIGRATE will preserve current SAS file attributes and is
recommended for converting all your SAS libraries from any
SAS 8 release to SAS 9.  For details and examples, please see
http://support.sas.com/rnd/migration/index.html

这是在 RH Linux 服务器上运行的。

任何建议将不胜感激。

谢谢并恭祝安康，

这听起来像是您服务器上的空间问题。您的默认目录中的文件系统有多大（根据您的libname sasdata '.';声明）？使用 Oracle 表引用上的数据集选项obs=1创建一个包含一行的新 SAS 数据集并检查变量。 

data sasdata.dummy_test;
     set myora.expt_tabl(obs=1);
run;

也许有非常大的 VARCHAR 或 BLOB 列占用了太多空间。请记住，SAS 没有 VARCHAR 类型。

虽然我不完全确定，但我相信主要问题是我最初试图在目录中创建/写入数据集，这在某种（？）意义上受到限制。这间接造成了麻烦，因为创建的数据集有缺陷。当我在其他地方创建它时，没关系。

谢谢和问候， Dibyendu
