Question

i have two mysql tables – employee and employee_log

i have written below trigger for it, intention is, what data is inserted in employee same data should be inserted in employee_log.

    delimiter |
    CREATE TRIGGER `emp`  
    AFTER INSERT ON `employee` 
    FOR EACH ROW  
    BEGIN  
    INSERT INTO employee_log (id,userId,firstname,lastname)  
    VALUES (NEW.id,NEW.userId,NEW.firstname,NEW.lastname);  
    END |

above trigger is executes well,
Now i have tried insert record in employee table it is giving me below error, i have no idea what went wrong here, please help ..

     Error is -
 #1436 - Thread stack overrun: 5848 bytes used of a 131072 byte stack, and 128000 bytes needed. Use 'mysqld -O thread_stack=#' to specify a bigger stack.   

Answer 1

try setting value of thread_stack global variable to default value 196608 in my.cnf file and then restart the MySQL server also try:

thread_stack = 256K

I hope you find answer here: MySQL error 1436: Thread stack overrun, with simple query
