这不是一个纯粹的 Teradata 问题。我不是要求在 Teradata 中创建易失性表。OLEDB对于使用从 SAS 连接到 Teradata的人来说，这是一个问题。我知道Volatile tables可以使用SQL assistant或什至在心跳中创建Teradata Interface to SAS. 但是，如果有些用户不在 SAS 网格上，并且他们没有安装 SAS i/f to teradata 并且他们使用 OLEDB 连接 SAS 和 Teradata。

这是一段使用 OLEDB 运行良好的代码片段，它给出了一些我们在说什么的想法。

下面的代码将运行良好：

proc sql;
connect to OLEDB(Provider='MSDASQL' Extended_Properties='DRIVER={Teradata};DBCNAME=UDWPROD;AUTHENTICATION=ldap' UID="&DMID" PWD="&DMPWD");
  create table out.TB as 
  select a.*, b.C7
  from connection to OLEDB
(select 
DB.C1,
DB.C2,
from 
DB
) as a inner join mytb as b
on DB.C9=b.C9
and (intnx('year',b.C7,-1,'same') le a.fst_srvc_dt lt intnx('year',b.C7,1,'same'));
%put &sqlxmsg ;
disconnect from OLEDB ;
quit;

按照同样的思路，我们尝试运行它，但要么存在语法错误（希望如此），要么它不喜欢它（对此感到很沮丧..不会太好）：

  proc sql;
  connect to OLEDB(Provider='MSDASQL' Extended_Properties='DRIVER={Teradata};DBCNAME=SITEPRD;AUTHENTICATION=ldap' UID="&DMID" PWD="&DMPWD");
  execute (create multiset volatile table idlist (my_id integer, mydate date)
  ON COMMIT PRESERVE ROWS) by teradata;
  execute (COMMIT WORK) by teradata;
  insert into idlist
  select distinct MyId_sas, mydate
  from mysource;
quit; 3:52 PM 
And got this output: 3:52 PM 
proc sql;
28     connect to OLEDB(Provider='MSDASQL' Extended_Properties='DRIVER={Teradata};
28 ! DBCNAME=SITEPRD;AUTHENTICATION=ldap' UID="&DMID" PWD="&DMPWD");

这是目前为 SAS 安装的 AFAIK

你如何让它工作？

我没有要引用的 teradata 实例，但我认为您的问题是您没有使用引用名称创建 oledb 连接，然后您尝试将其引用为“teradata”。

尝试这个：

connect to OLEDB as teradata (Provider='MSDASQL' Extended_Properties='DRIVER={Teradata};DBCNAME=SITEPRD;AUTHENTICATION=ldap' UID="&DMID" PWD="&DMPWD");

你有两个错误。首先，您定义了一个连接OLEDB，然后尝试在名为未定义的连接上执行命令TERADATA。添加AS TERADATA到您的CONNECT语句以便命名连接或更改EXECUTE语句以改用OLEDB连接名称。

最后，您的插入语句还将在 SAS WORK 库中创建一个表。您是否期望它能够插入或读取 OLEDB 连接？如果要将 SAS 中的数据插入 Teradata 表，则需要创建指向 Teradata 的 libref。无需先“创建”表。SAS 很乐意为您创建表格。

libname TERADATA OLEDB ... connection details ... ;
proc sort data=mysource(keep=myid_sas mydate) nodupkey out=TERADATA.idlist;
  by _all_;
run;
