以下給出如何實現MYSQL數據表更新實時觸發sql server裡面對應表的增刪改操作，首先，增加原來的mysql的表的觸發器，包括以下三個：
插入數據： delimiter || DROP TRIGGER IF EXISTS t_afterinsert_on_accounts || CREATE TRIGGER t_afterinsert_on_accounts AFTER INSERT ON sugarcrm642ce.accounts FOR EACH ROW BEGIN insert into sugarcrm642cebackup.accountsbackup (`id`, `name`, `date_entered`, `date_modified`, `modified_user_id`, `created_by`, `description`, `deleted`, `assigned_user_id`, `account_type`, `industry`, `annual_revenue`, `phone_fax`, `billing_address_street`, `billing_address_city`, `billing_address_state`, `billing_address_postalcode`, `billing_address_country`, `rating`, `phone_office`, `phone_alternate`, `website`, `ownership`, `employees`, `ticker_symbol`, `shipping_address_street`, `shipping_address_city`, `shipping_address_state`, `shipping_address_postalcode`, `shipping_address_country`, `parent_id`, `sic_code`, `campaign_id`, `BehaviorType`) values(new.id,new.name,new.date_entered,new.date_modified,new.modified_user_id,new.created_by,new.description,new.deleted, new.assigned_user_id,new.account_type,new.industry,new.annual_revenue,new.phone_fax,new.billing_address_street,new.billing_address_city,new.billing_address_state, new.billing_address_postalcode,new.billing_address_country,new.rating,new.phone_office,new.phone_alternate,new.website,new.ownership,new.employees,new.ticker_symbol, new.shipping_address_street,new.billing_address_city,new.shipping_address_state,new.shipping_address_postalcode,new.shipping_address_country,new.parent_id, new.sic_code,new.campaign_id,'I'); END|| 更新觸發器 delimiter || DROP TRIGGER IF EXISTS t_afterupdate_on_accounts || CREATE TRIGGER t_afterupdate_on_accounts AFTER update ON sugarcrm642ce.accounts FOR EACH ROW BEGIN insert into sugarcrm642cebackup.accountsbackup (`id`, `name`, `date_entered`, `date_modified`, `modified_user_id`, `created_by`, `description`, `deleted`, `assigned_user_id`, `account_type`, `industry`, `annual_revenue`, `phone_fax`, `billing_address_street`, `billing_address_city`, `billing_address_state`, `billing_address_postalcode`, `billing_address_country`, `rating`, `phone_office`, `phone_alternate`, `website`, `ownership`, `employees`, `ticker_symbol`, `shipping_address_street`, `shipping_address_city`, `shipping_address_state`, `shipping_address_postalcode`, `shipping_address_country`, `parent_id`, `sic_code`, `campaign_id`, `BehaviorType`) values(new.id,new.name,new.date_entered,new.date_modified,new.modified_user_id,new.created_by,new.description,new.deleted, new.assigned_user_id,new.account_type,new.industry,new.annual_revenue,new.phone_fax,new.billing_address_street,new.billing_address_city,new.billing_address_state, new.billing_address_postalcode,new.billing_address_country,new.rating,new.phone_office,new.phone_alternate,new.website,new.ownership,new.employees,new.ticker_symbol, new.shipping_address_street,new.billing_address_city,new.shipping_address_state,new.shipping_address_postalcode,new.shipping_address_country,new.parent_id, new.sic_code,new.campaign_id,'U'); END|| 刪除觸發器 delimiter || DROP TRIGGER IF EXISTS t_afterdelete_on_accounts || CREATE TRIGGER t_afterdelete_on_accounts AFTER delete ON sugarcrm642ce.accounts FOR EACH ROW BEGIN insert into sugarcrm642cebackup.accountsbackup (`id`, `name`, `date_entered`, `date_modified`, `modified_user_id`, `created_by`, `description`, `deleted`, `assigned_user_id`, `account_type`, `industry`, `annual_revenue`, `phone_fax`, `billing_address_street`, `billing_address_city`, `billing_address_state`, `billing_address_postalcode`, `billing_address_country`, `rating`, `phone_office`, `phone_alternate`, `website`, `ownership`, `employees`, `ticker_symbol`, `shipping_address_street`, `shipping_address_city`, `shipping_address_state`, `shipping_address_postalcode`, `shipping_address_country`, `parent_id`, `sic_code`, `campaign_id`, `BehaviorType`) values(old.id,old.name,old.date_entered,old.date_modified,old.modified_user_id,old.created_by,old.description,old.deleted, old.assigned_user_id,old.account_type,old.industry,old.annual_revenue,old.phone_fax,old.billing_address_street,old.billing_address_city,old.billing_address_state, old.billing_address_postalcode,old.billing_address_country,old.rating,old.phone_office,old.phone_alternate,old.website,old.ownership,old.employees,old.ticker_symbol, old.shipping_address_street,old.billing_address_city,old.shipping_address_state,old.shipping_address_postalcode,old.shipping_address_country,old.parent_id, old.sic_code,old.campaign_id,'D'); END||
上面必須增加behaviortype字段，因為如果是I代表插入，U代表更新，D代表刪除，接著增加mysql的備份表，專門記錄這三種操作。

最後建立sql server存儲過程，這邊尤其要注意的是要rtrim mysql char類型，因為sql server對這個是完全填充的，如果有多余空格插入會報錯，同時 要定義為 別名，因為在 下面的插入是根據別名字段來的。

最後再開啟sql server代理，因為本身這個需要計劃任務每秒去monitor這個mysql變化，因為sql server這邊只能設置10秒更新一次，那這邊就只能如此，如果要看是否成功，可以右擊該計劃任務查看歷史記錄。
