sql - 如何在proc SQL的from表中使用宏变量

Question

我需要在下面的 SQL 传递代码中使用宏变量，但不断收到错误，我不知道如何修复它！

%let mon1 = 201209;
proc sql;
/*Connection String*/
connect to odbc as sqldata (noprompt="uid=dr;pwd=raven;dsn=FinanceDW;") ;
create table output1 as /*This will create a SAS data set*/
 select * /*this will select all from the command below and insert into the SAS         dataset*/
  from connection to sqldata
     ( /*Insert SQL CODE below - it can only use SQL any SAS code will cause it to fail*/
select top 10 *     
from "AUS_&mon1._FCM15.dbo.contract"

   );/*End SQL code*/

disconnect from sqldata;/*Close connection*/
quit;

然后我收到以下错误（从日志中提取）：

23          select top 10 *     
24          from "AUS_&mon1._FCM15.dbo.contract"
25         
26                );
ERROR: CLI describe error: [Microsoft][ODBC SQL Server Driver][SQL Server]Invalid object name 
       'AUS_201209_FCM15.dbo.contract'. : [Microsoft][ODBC SQL Server Driver][SQL Server]Statement(s) 
       could not be prepared.

我需要从中获取数据的实际表称为 AUS_201209_FCM15 所以我不知道问题是什么？

弄清楚了。需要使用%bquote和删除""：

%let mon1 = 201209; 
proc sql; 
connect to odbc as sqldata (noprompt="uid=dr;pwd=raven;dsn=FinanceDW;") ; 
create table output1 as 
select * 
from connection to sqldata     
select top 10 *      
from %bquote(AUS_&mon1._FCM15.dbo.contract)
);
disconnect from sqldata
quit;
