未分配 Libref

Question

我正在尝试从 TAQ（每日交易数据库）查询数据。在 SAS 中，我做了以下操作，但 sas 抱怨说，"Library does not exist." 我确定路径是正确的。

%let wrds = wrds.wharton.upenn.edu 4016;options comamid = TCP remote=WRDS;
signon username=_prompt_;
*************************************************************************;
libname ct'/wrds/nyse/sasdata/taqms/ct';
rsubmit;

日志说：

NOTE: Libname CT refers to the same physical library as TAQMSE.
WARNING: Library CT does not exist.
NOTE: Libref CT was successfully assigned as follows:
      Engine:        V9
      Physical Name: C:\wrds\nyse\sasdata\taqms\ct
      rsubmit;
NOTE: Remote submit to WRDS commencing.

但是当我第一次登录到wrds服务器时，我看到了路径，第一个引擎给出了我想使用的库的路径。为了设置库，我做错了什么？

NOTE: Libref TAQMSEC was successfully assigned as follows:
      Levels:           5
      Engine(1):        V9
      Physical Name(1): /wrds/nyse/sasdata/taqms/ct
      Engine(2):        V9
      Physical Name(2): /wrds/nyse/sasdata/taqms/cq

Answer 1

您似乎正试图在本地会话中引用远程库。在 rsubmit; 块中分配远程库后，尝试运行以下操作（因此，在 endrsubmit; 语句之后）：

 libname CT (TAQMSEC) server=WRDS;
