cursore within prusider mysql - mysql

Question

i'm trying to slice a long double Column by Varied size , and insert it with cursor to new table that has this size of columns amount.
the trouble is the cursor isn't responding?
I tried to activate the cursor (Externally) manually And managed to.
So I have the impression cursor does not work within procedure?!
Here's the code:
The outer procedure:
CREATE DEFINER=`root`#`localhost` PROCEDURE `slice_arrays`(IN `size` INT)
DETERMINISTIC
BEGIN
DECLARE n INT DEFAULT 0;
DECLARE h INT DEFAULT 0;
DECLARE q_creat text DEFAULT "";
DECLARE cell text DEFAULT "cell";
DECLARE cell_type text DEFAULT "double";
DECLARE new_table_name text DEFAULT "";
set new_table_name=CONCAT("table_1440_slice_by_",size);
SELECT COUNT(*) FROM eurusd_1440_minute_timeframe_chart_bars INTO n;
SET #q_creat =CONCAT("CREATE TABLE IF NOT EXISTS ",new_table_name," (");
WHILE h < size DO
SET #q_creat = CONCAT(#q_creat,cell,h," ",cell_type);
set #h_pluse_1=h+1;
if #h_pluse_1 = size THEN
SET #q_creat= CONCAT(#q_creat,")");
else
SET #q_creat= CONCAT(#q_creat,",");
end if;
set h=h+1;
END WHILE;
PREPARE stmt1 FROM #q_creat;
EXECUTE stmt1;
DEALLOCATE PREPARE stmt1;
TRUNCATE TABLE new_table_name;
set h=0;
set #temp_cuonter=size;
WHILE #temp_cuonter <= n DO
drop table IF EXISTS temp_table;
create table temp_table as (SELECT * FROM table_1440_test3 LIMIT h , size);
CALL insert_into_selected_table_from_temp_table(new_table_name);
set h=h+1;
set #temp_cuonter =#temp_cuonter+1;
TRUNCATE TABLE tamp_table;
end while;
End
The nested procedure:
CREATE DEFINER=`root`#`localhost` PROCEDURE `insert_into_selected_table_from_temp_table`(IN `table_name` TEXT)
DETERMINISTIC
begin
set #insert_q= CONCAT("INSERT INTO ",table_name," VALUES(");
set #insert_q= CONCAT(#insert_q,get_temp_table(),")");
PREPARE stmt2 FROM #insert_q;
EXECUTE stmt2;
DEALLOCATE PREPARE stmt2;
end
thanks!
