Can I use a variable name from a cursor loop in an update statement within said loop … in a trigger?

OPEN cursor1;
cursor_loop:LOOP
FETCH cursor1 INTO l_customer_name;
IF l_last_row_fetched=1 THEN
LEAVE cursor_loop;
END IF;
UPDATE l_customer_name SET active = 1 WHERE customer_id = NEW.id;
END LOOP cursor_loop;
CLOSE cursor1;

right now, when i run this, i get ‘l_customer_name’ table does not exist.

I had very bad experience with mysql stored procedure and triggers. I think mysql should provide a tool for stored procedure programming with debug facility.

oops, meant
DECLARE EXIT HANDLER FOR SQLEXCEPTION BEGIN
— in here, how do I see what the error was, and what message MySQL would have returned?
END;

Inside DECLARE EXIT HANDLER ON SQLEXCEPTION, is there any way to find the error code and/or message that MySQL would have returned to the caller if the handler wasn’t there?

Or is it necessary to write an individual handler for each and every possible error code in each and every stored procedure…

I completely agree. MySQL is clearly sub-par in many aspects, specifically the development tools. DECLARE statements that work in some contexts and not others, variable initialization inconsistencies, lack of debugging ability in the provided tools, IF/CONDITIONAL confusion, operator confusion ( :=/= ), and the list goes on an on. Maybe they should hire Anders Hejlsberg to fix this lemon. My guess is Sun will make this better but then charge for tools that target real devs.

They’re very fortunate it’s a free tool. Otherwise I’m quite sure it would have been abandon years ago.
