while loop terminating after fetching some data - mysql

Question

I have written a procedure that creates a temporary table and executes a query by fetching the rows from the temporary table.I have around 13486 rows in the temporary table.But when i am calling the procedure i observed that the procedure is getting terminated after fetching 107 rows from the temporary table.Moreover i also observed that this value is not constant..Sometimes it is 107 the other time it is 114 and some other time it is just 100.Why this happens?Please need help?Somebody please..Here is my procedure.And i came to know that while loop will terminate for >1000 iterations.Please suggest me a method to overcome this.
DELIMITER $$
DROP PROCEDURE IF EXISTS `lookup`.`test` $$
CREATE PROCEDURE `lookup`.`test` ()
BEGIN
CREATE TEMPORARY TABLE lookup.airportname(id int AUTO_INCREMENT,PRIMARY KEY(id))
AS (select distinct airport_id from lookup.airport);
SET #num=0;
SET #arpt=NULL;
SELECT count(*) INTO #num FROM airportname;
SET #i=0;
while #i<#num do
SELECT airport_id INTO #arpt FROM airportname WHERE id=#i;
select #arpt,#i;
set #i=#i+1;
end while;
END $$
DELIMITER ;
I am using mysql query browser.Thank you.

Answer 1

If you want to insert value into id Then it should not be auto_increment. - Remove auto_increment from table definition, it should work

Answer 2

delimiter |
create procedure employee_select()
Begin
Declare empno,done int(9);
Declare emp_select Cursor for select emp_no from gross_salary ;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;
Open emp_select; // cursor opening
read_loop: loop // start looping all the datas one by one
fetch emp_select into empno; // fetching the select value into variable empno
//note :variable name should not be same as columne name in select statement"
IF done THEN
LEAVE read_loop; // if no more rows, this makes it to leave the loop"
END IF;
//Enter the code you want do for each row
end loop;
close emp_select;
End |
