如何引用雪花任务中调用的存储过程的返回值

Question

I have a user defined stored procedure that returns a VARIANT type in snowflake. I would like to call this procedure from a task and log the return value into tables.

The task would look something like this:

CREATE OR REPLACE TASK MY_TASK 
  SCHEDULE = '5 minute'
WHEN 
  SYSTEM$STREAM_HAS_DATA('MY_STREAM') 
AS
CALL MY_PROCEDURE();

/* This procedure could return the following metrics that I need to log.
{
  timestamp: 1234567890,
  rows_affected: 1234,
  success: true
}
*/

Is this possible or do I need to include logging in the procedure?

Answer 1

Any single SQL statement, or a call to a stored procedure, executed when the task runs.

You have to log it inside the stored procedure.
