Question

Given error: #1436 – Thread stack overrun: 6024 bytes used of a 131072 byte stack, and 128000 bytes needed. Use ‘mysqld -O thread_stack=#’ to specify a bigger stack.

DROP TRIGGER IF EXISTS `After_delete_area_package`;
DELIMITER //
CREATE TRIGGER `After_delete_area_package` AFTER DELETE ON `area_package`
FOR EACH ROW BEGIN    
DELETE FROM accounts_areas
WHERE (area_id = 1); 
END
//
DELIMITER ;

simple as hell i would guess.
The only area_id in table accounts_areas is 1
Before that i tried old.package_area_id

I do not have foreign key restraints and my overhead goes red in phpMyAdmin set to 28B.

Question: Why would my trigger not delete all the rows from accounts_areas where area_id = 1

Answer 1

Could you perhaps be missing an END?

DROP TRIGGER IF EXISTS After_delete_area_package;

DELIMITER $$
CREATE TRIGGER After_delete_area_package AFTER DELETE ON area_package
FOR EACH ROW
BEGIN
DELETE FROM accounts_areas
    WHERE area_id = 1;
END$$
DELIMITER;

Edit 1

Since you are reviving a thread_stack error, the solution would would be to increase the stack size.
