如何使用OLEDB连接器在SAS

这不是纯粹的Teradata问题。我不是要求在Teradata中创建一个易失性表。对于使用来自SAS的Teradata的OLEDB连接的人来说,这是一个问题。我知道可以使用Volatile tables甚至SQL assistant在心跳中创建Teradata Interface to SAS。但是,如果有用户不在SAS网格上并且他们没有安装SAS i / f到teradata,他们使用OLEDB连接SAS和Teradata。

以下是使用OLEDB运行良好的代码片段,它让我们知道我们在谈论什么。

下面的代码运行良好:

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;

沿着同样的路线,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(对此有点太糟糕了......)

  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

你如何让它发挥作用?

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,那么您尝试将其引用为“teradata”。

试试这个:

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,您定义了与OLEDB的连接,然后尝试在未定义的名为TERADATA的连接上执行命令。将AS TERADATA添加到CONNECT语句,以便建立连接或更改EXECUTE语句以使用OLEDB连接名称。

最后,您的插入语句将在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?如果要将数据从SAS插入Teradata表,则需要创建指向Teradata的libref。没有必要"创建"该表首先。 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;
