"Invalid cursor state" odbc 加载命令出错

Question

这个神秘错误是什么意思？

> odbc load, exec("
> CREATE VOLATILE MULTISET TABLE vol_tab AS (
>         SELECT TOP 10 user_id FROM dw_users
> )
> WITH DATA
> PRIMARY INDEX(user_id)
> ON COMMIT PRESERVE ROWS;
> ") clear dsn("mozart");
The ODBC driver reported the following diagnostics
[Teradata][ODBC Teradata Driver] Invalid cursor state.
SQLSTATE=24000
r(693);

Answer 1

您收到此错误是因为您告诉 Stata 加载某些内容，但您的代码没有不属于 table 创建的 SELECT 子句。如果在底部添加 SELECT 子句，它将起作用。

或者，如果您只想创建 table.

，则可以使用 odbc exec("SqlStmt") 语法

这是一个例子：

/* Works */
odbc load, exec("
CREATE VOLATILE MULTISET TABLE vol_tab AS (
    SELECT TOP 10 user_id FROM dw_users
)
WITH DATA
PRIMARY INDEX(user_id)
ON COMMIT PRESERVE ROWS;

SELECT * FROM vol_tab;
") clear dsn("mozart") lowercase multistatement;
format user_id %20.0fc;
sort user_id;
list, clean noobs;

/*Also Works */
odbc exec("
CREATE VOLATILE MULTISET TABLE vol_tab AS (
    SELECT TOP 10 user_id FROM dw_users
)
WITH DATA
PRIMARY INDEX(user_id)
ON COMMIT PRESERVE ROWS;
"), dsn("mozart");

/* Fails: Load With No Bottom Select Clause */
odbc load, exec("
CREATE VOLATILE MULTISET TABLE vol_tab AS (
    SELECT TOP 10 user_id FROM dw_users
)
WITH DATA
PRIMARY INDEX(user_id)
ON COMMIT PRESERVE ROWS;
") clear dsn("mozart");
