I got the issue ..Issue is related to table definition see below
CREATE TABLE `group_distribution` (
`gd_id` int(11) NOT NULL,
`gd_tweet` varchar(500) CHARACTER SET latin1 NOT NULL,
`gd_ht` varchar(45) CHARACTER SET latin1 DEFAULT NULL,
`gt_created_by` int(11) DEFAULT NULL,
`gt_team_lead` int(11) DEFAULT NULL,
`gt_send_to` int(11) DEFAULT NULL,
`gt_added_dt` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
`gt_update_dt` timestamp NULL DEFAULT NULL,
`gt_active_flag` tinyint(1) NOT NULL,
PRIMARY KEY (`gd_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Here you can check it clearly show gd_tweet` varchar(500) CHARACTER SET latin1 NOT NULL, have diffrent characterset thats why created issue now i changed it to
CREATE TABLE `group_distribution` (
`gd_id` int(11) NOT NULL,
`gd_tweet` varchar(500) CHARACTER SET utf8 NOT NULL,
`gd_ht` varchar(45) CHARACTER SET utf8 DEFAULT NULL,
`gt_created_by` int(11) DEFAULT NULL,
`gt_team_lead` int(11) DEFAULT NULL,
`gt_send_to` int(11) DEFAULT NULL,
`gt_added_dt` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
`gt_update_dt` timestamp NULL DEFAULT NULL,
`gt_active_flag` tinyint(1) NOT NULL,
PRIMARY KEY (`gd_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
