Answer 1

I got the answer

First create new function

CREATE FUNCTION SPLIT_STR(x VARCHAR(255), delim VARCHAR(12), pos INT)
RETURNS VARCHAR(255)
RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(x, delim, pos),
LENGTH(SUBSTRING_INDEX(x, delim, pos -1)) + 1), delim, '');

Then create stored procedure

DELIMITER ;;
CREATE PROCEDURE Split(in fullstr varchar(255))
BEGIN
    DECLARE a INT Default 0 ;
    DECLARE str VARCHAR(255);

    DROP TABLE IF EXISTS my_temp_table;
    CREATE temporary TABLE my_temp_table(ID INT AUTO_INCREMENT NOT NULL, description text, primary key(ID));

    simple_loop: LOOP
        SET a=a+1;
        SET str=SPLIT_STR(fullstr,",",a);
        IF str='' THEN
            LEAVE simple_loop;
        END IF;
        #Do Inserts into temp table here with str going into the row
        insert into my_temp_table (description) values (str);
   END LOOP simple_loop;
   select * from my_temp_table;
END

After that when i call it by call Split('asas,d,sddf,dfd'); it gives me the output that what i want.

Thanx for every suggestion.
