Answer 1

First Create Procedure as Below:

CREATE DEFINER=`root`@`%` PROCEDURE `sp_split`(str nvarchar(6500), dilimiter varchar(15), tmp_name varchar(50))
BEGIN

    declare end_index   int;
    declare part        nvarchar(6500);
    declare remain_len  int;

    set end_index      = INSTR(str, dilimiter);

    while(end_index   != 0) do

        /* Split a part */
        set part       = SUBSTRING(str, 1, end_index - 1);

        /* insert record to temp table */
        call `sp_split_insert`(tmp_name, part);

        set remain_len = length(str) - end_index;
        set str = substring(str, end_index + 1, remain_len);

        set end_index  = INSTR(str, dilimiter);

    end while;

    if(length(str) > 0) then

        /* insert record to temp table */
        call `sp_split_insert`(tmp_name, str);

    end if;

END

After that create procedure as below:

CREATE DEFINER=`root`@`%` PROCEDURE `sp_split_insert`(tb_name varchar(255), tb_value nvarchar(6500))
BEGIN
    SET @sql = CONCAT('Insert Into ', tb_name,'(item) Values(?)'); 
    PREPARE s1 from @sql;
    SET @paramA = tb_value;
    EXECUTE s1 USING @paramA;
END

How call test

CREATE DEFINER=`root`@`%` PROCEDURE `test_split`(test_text nvarchar(255))
BEGIN

    create temporary table if not exists tb_search
        (
            item nvarchar(6500)
        );

    call sp_split(test_split, ',', 'tb_search');

    select * from tb_search where length(trim(item)) > 0;

    drop table tb_search;

END


call `test_split`('Apple,Banana,Mengo');
