Stata odbc SQL 一个查询中的多个 CTE

Question

我正在尝试在 "odbc load, exec("WITH...”语句中执行多个 CTE 表达式。我确认这两个 CTE 提取了所需的信息。

但是，Stata 似乎不喜欢使用两个 CTE。我试图用分号将两者分开，例如 SQL 状态，但它 returns "Incorrect syntax near ';'.

有什么建议吗？这是我要查看的代码：

. #delimit ;
delimiter now ; 
. odbc load, exec("
> WITH BIRegionSIC (Region, BranchID, Branch, SIC, CoreMarket, MarketSegment)
>         AS
>         (

The ODBC driver reported the following diagnostics
[Microsoft][ODBC SQL Server Driver][SQL Server]Incorrect syntax near ';'.
SQLSTATE=42000
r(682);

end of do-file

r(682);

感谢任何建议！我定界以便代码在 do 文件中可读，并且运行没有将定界符设置为分号会导致相同的错误。

此致，

您应该按以下方式声明多个 CTE：

WITH cte AS (
)

, cte2 AS (
)

不是通过多次使用 WITH-子句。
