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提取所需的信息。

然而，Stata似乎并不喜欢使用两个CTE。我尝试用分号分隔两者，比如SQL状态，但它返回“'语法不正确';'。”。

有什么建议吗？这是我要查看的代码：

. #delimit ;
delimiter now ; 
. odbc load, exec("

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);

感谢您的任何建议！我分界，因此代码在do文件中是可读的，并且在没有将分隔符设置为分号的情况下运行会导致相同的错误。

此致

您应该通过以下方式声明多个CTE：

WITH cte AS (
)

, cte2 AS (
)

多次使用WITH - 子句。

Stata odbc SQL多个CTE在一个查询中
