Snowflake - Getting invalid identifier error while passing variables between SQL Stored Procs

问题

I have a Snowflake SQL stored procedure from where I'm trying to call the SYSTEM$SEND_EMAIL function, but its erroring out as below:

`create or replace procedure testsproc()
RETURNS VARCHAR
language sql 
as
$$
BEGIN
  SELECT * FROM non_existent_table;
EXCEPTION
  WHEN OTHER THEN
    LET LINE := SQLCODE || ': ' || SQLERRM;
    INSERT INTO myexception VALUES (:LINE); -- this line works
    call SYSTEM$SEND_EMAIL('MYEMAIL','abc@mail.com','Errors!!',LINE); -- this line is throwing the error invalid identifier 'LINE' (line 320)
    return line;
END;
$$`

I tried passing :LINE to system$send_email, it still isn't working. What am I doing wrong?

Any help is much appreciated.

得分: 1

缺少一个冒号,与脚本上一行使用的冒号相同:

修正后:

    call SYSTEM$SEND_EMAIL('MYEMAIL','abc@mail.com','Errors!!', :LINE); 

通过这样做,我会在我的电子邮件中得到所需的异常:

Snowflake – 在 SQL 存储过程之间传递变量时出现无效标识符错误。

英文:

It's missing a colon, the same colon the script uses in the previous line:

Fixed:

    call SYSTEM$SEND_EMAIL('MYEMAIL','abc@mail.com','Errors!!', :LINE); 

With that, I get the desired exception in my email:
