To re-create the schema for the table, you can run the following SQL (I have adapted the table name for the prefix in your original post):
CREATE TABLE `sl8j_customer_entity` ( `entity_id` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT 'Entity Id', `entity_type_id` smallint(5) unsigned NOT NULL DEFAULT '0' COMMENT 'Entity Type Id', `attribute_set_id` smallint(5) unsigned NOT NULL DEFAULT '0' COMMENT 'Attribute Set Id', `website_id` smallint(5) unsigned DEFAULT NULL COMMENT 'Website Id', `email` varchar(255) DEFAULT NULL COMMENT 'Email', `group_id` smallint(5) unsigned NOT NULL DEFAULT '0' COMMENT 'Group Id', `increment_id` varchar(50) DEFAULT NULL COMMENT 'Increment Id', `store_id` smallint(5) unsigned DEFAULT '0' COMMENT 'Store Id', `created_at` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00' COMMENT 'Created At', `updated_at` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00' COMMENT 'Updated At', `is_active` smallint(5) unsigned NOT NULL DEFAULT '1' COMMENT 'Is Active', `disable_auto_group_change` smallint(5) unsigned NOT NULL DEFAULT '0' COMMENT 'Disable automatic group change based on VAT ID', PRIMARY KEY (`entity_id`), UNIQUE KEY `UNQ_CUSTOMER_ENTITY_EMAIL_WEBSITE_ID` (`email`,`website_id`), KEY `IDX_CUSTOMER_ENTITY_STORE_ID` (`store_id`), KEY `IDX_CUSTOMER_ENTITY_ENTITY_TYPE_ID` (`entity_type_id`), KEY `IDX_CUSTOMER_ENTITY_EMAIL_WEBSITE_ID` (`email`,`website_id`), KEY `IDX_CUSTOMER_ENTITY_WEBSITE_ID` (`website_id`), CONSTRAINT `FK_CUSTOMER_ENTITY_STORE_ID_CORE_STORE_STORE_ID` FOREIGN KEY (`store_id`) REFERENCES `sl8j_core_store` (`store_id`) ON DELETE SET NULL ON UPDATE CASCADE, CONSTRAINT `FK_CUSTOMER_ENTITY_WEBSITE_ID_CORE_WEBSITE_WEBSITE_ID` FOREIGN KEY (`website_id`) REFERENCES `sl8j_core_website` (`website_id`) ON DELETE SET NULL ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='Customer Entity';
However, as MagenX pointed out, the fact that this table is missing very much points at a broken installation and chances are there are other tables and/or fields missing. You can try running the above query, just to see if it gets you going, but I'd strongly recommend a fresh install/restore from backup.
Thanks iweb_bas!
That created the table perfectly. I can now view orders and customer information in the dashboard Sales->Orders. Even the older ones before I added the customer_entity table.
However when I go to Reports->Sales->Orders they do not show up. Is there a setting I'm missing (hopefully not more tables, with the customer entity table there are now 250 tables)?
Thanks again!
