如何在 MySQL 中获取存储过程的执行历史

I have created a stored procedure in MySQL named: inventory_procedure(fromDateTime)

A third party system executes this stored procedure at regular 1 hour interval by passing fromDateTime in dd-mm-yyyy hh:mm:ss format.

Sometimes, third party systems reports that stored procedure didn't returned any data.

When I hit the stored procedure it returns results for me.

is there any way where I can fetch information like:

1. When stored procedure was executed?
2. What was the fromDateTime passed in storedProcedure?
3. How many rows stored procedure returned?

Create a log table like this one:

create table inventory_procedure_log (
  id int unsigned auto_increment primary key,
  ts timestamp,
  fromDateTime datetime,
  rows_returned int
);

You will probably want to include some indexes for fast searches.

Insert the log entries within your procedure right after the final SELECT:

create procedure inventory_procedure (fromDateTime datetime)
begin
  -- random dummy result set
  select n
  from (select 1 n union select 2 union select 3) as x
  where rand() < 0.5;
  
  -- insert log entry
  insert into inventory_procedure_log(ts, fromDateTime, rows_returned) values (
    now(),
    fromDateTime,
    found_rows()
  );
end

Now you can search in your log table. For example - show all entries for the last 24 hours:

select *
from inventory_procedure_log
where ts > now() - interval 24 hour;

You can extend the log table for more info (like session ID) as needed.
