I'm trying to filter the records with where clause in procedure based on IN input parameter values I had written the stored procedure in My SQL as like below :

SQL

DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_get_logs_Test`(IN `p_Bot_Ids` VARCHAR(500))
    NO SQL
select id, bot_id, log_level,log_type,time_stamp,finger_print,windows_identity,machine_name,process_name,process_version
,job_Id,robot_name,machine_Id,file_name,message,created_date from log
where id < 200 and
bot_id IN (p_Bot_Ids)$$
DELIMITER ;

What I have tried:

My "p_Bot_Ids" is a comma separated string. If I pass "1,2" its filtering only with "1". if I pass "2,1" its filtering with only "2".

Also my "p_Bot_Ids" can also be null.In that case I needs to pull out all the records.

Let us consider there are 50 records in my table. If i pass "p_Bot_Ids" = "1,2,3" I needs to get only 1,2,3 Ids records(total 3 rows) only. If I pass "p_Bot_Ids" = NULL then I should get all my 50 records.

I'm unfamiliar with MySQL, but how about something like this, which might work with SQL Server:
WHERE CHARINDEX ( ',' + bot_id + ',' , ',' + p_Bot_Ids + ',' ) > 0

The requirements are a bit different in different parts or your post but if the following is correct

You could try something like

SQL

DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `sp_get_logs_Test`(IN `p_Bot_Ids` VARCHAR(500))
    NO SQL

SET @sql := 'select id, bot_id, log_level,log_type,time_stamp,finger_print,windows_identity,machine_name,process_name,process_version
,job_Id,robot_name,machine_Id,file_name,message,created_date from log
where id < 200';

IF p_Bot_Ids IS NOT NULL THEN
   SET @sql := CONCAT(@sql, ' AND bot_id IN (', p_Bot_Ids, ')');
END IF ;

PREPARE mystatement FROM @sql;
EXECUTE mystatement;
DEALLOCATE PREPARE mystatement$$
DELIMITER ;
