Re Indexing problem | magento indexing | Re-indexing required

Here is the solution for all re-indexing But you have to follow my step.

===========================================
DROP TABLE IF EXISTS `index_process_event`;
DROP TABLE IF EXISTS `index_event`;
DROP TABLE IF EXISTS `index_process`;

//first step Complete///////

CREATE TABLE `index_event` (
`event_id` BIGINT(20) UNSIGNED NOT NULL AUTO_INCREMENT,
`type` VARCHAR(64) NOT NULL,
`entity` VARCHAR(64) NOT NULL,
`entity_pk` BIGINT(20) DEFAULT NULL,
`created_at` DATETIME NOT NULL,
`old_data` MEDIUMTEXT,
`new_data` MEDIUMTEXT,
PRIMARY KEY (`event_id`),
UNIQUE KEY `IDX_UNIQUE_EVENT` (`type`,`entity`,`entity_pk`)
) ENGINE=INNODB DEFAULT CHARSET=utf8;

CREATE TABLE `index_process` (
`process_id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
`indexer_code` VARCHAR(32) NOT NULL,
`status` ENUM('pending','working','require_reindex') NOT NULL DEFAULT 'pending',
`started_at` DATETIME DEFAULT NULL,
`ended_at` DATETIME DEFAULT NULL,
`mode` ENUM('real_time','manual') NOT NULL DEFAULT 'real_time',
PRIMARY KEY (`process_id`),
UNIQUE KEY `IDX_CODE` (`indexer_code`)
) ENGINE=INNODB DEFAULT CHARSET=utf8;

///second step complete//////////////////

INSERT INTO `index_process`(`process_id`,`indexer_code`,`status`,`started_at`,`ended_at`,`mode`) VALUES (1,'catalog_product_attribute','pending','2010-02-13 00:00:00','2010-02-13 00:00:00','real_time'),(2,'catalog_product_price','pending','2010-02-13 00:00:00','2010-02-13 00:00:00','real_time'),(3,'catalog_url','pending','2010-02-13 19:12:15','2010-02-13 19:12:15','real_time'),(4,'catalog_product_flat','pending','2010-02-13 00:00:00','2010-02-13 00:00:00','real_time'),(5,'catalog_category_flat','pending','2010-02-13 00:00:00','2010-02-13 00:00:00','real_time'),(6,'catalog_category_product','pending','2010-02-13 00:00:00','2010-02-13 00:00:00','real_time'),(7,'catalogsearch_fulltext','pending','2010-02-13 00:00:00','2010-02-13 00:00:00','real_time'),(8,'cataloginventory_stock','pending','2010-02-13 00:00:00','2010-02-13 00:00:00','real_time');

CREATE TABLE `index_process_event` (
`process_id` INT(10) UNSIGNED NOT NULL,
`event_id` BIGINT(20) UNSIGNED NOT NULL,
`status` ENUM('new','working','done','error') NOT NULL DEFAULT 'new',
PRIMARY KEY (`process_id`,`event_id`),

CONSTRAINT `FK_INDEX_EVNT_PROCESS` FOREIGN KEY (`event_id`) REFERENCES `index_event` (`event_id`) ON DELETE CASCADE ON UPDATE CASCADE,
