Mysql 批量修改

１、创建临时表－各业务敏感字段关系映射表

CREATE TABLE `encrypt_user_data` (

`uid` int(11) unsigned NOT NULL COMMENT '',

`encrypt_bank_card_id` varchar(252) NOT NULL COMMENT '',

`encrypt_phone` varchar(252) NOT NULL COMMENT '',

`encrypt_contract_no` varchar(252) NOT NULL COMMENT 'encrypt_contract_no',

`encrypt_email` varchar(252) NOT NULL COMMENT '',

`encrypt_86_phone` varchar(252) NOT NULL COMMENT '',

`encrypt_name` varchar(252) NOT NULL COMMENT '',

`encrypt_identity_id` varchar(252) CHARACTER SET utf16 NOT NULL COMMENT '',

`created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '',

`updated` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '更新时间',

PRIMARY KEY (`uid`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='用户敏感加密数据';

２、联表插入数据

INSERT IGNORE INTO encrypt_user_data

(uid,encrypt_bank_card_id,encrypt_phone,encrypt_contract_no,encrypt_email,encrypt_86_phone,encrypt_name,encrypt_identity_id)

SELECT b.uid AS uid,a.encrypted_bank_card_id AS encrypt_bank_card_id ,

a.encrypted_phone AS encrypt_phone ,a.encrypted_contract_no AS encrypt_contract_no,

b.email_safe AS encrypt_email,b.phone_safe AS encrypt_86_phone,c.encrypted_name AS encrypt_name,

c.encrypted_identity_id AS encrypt_identity_id

FROM t_formax_user_info as b

LEFT JOIN t_bank_card_pay_info as a on b.uid=a.uid

LEFT JOIN t_user_base_info as c on b.uid=c.uid;

３、更新各业务敏感字段值

UPDATE customers,encrypt_user_data

SET customers.email=encrypt_user_data.encrypt_email,customers.phone=encrypt_user_data.encrypt_86_phone,

customers.id_number=encrypt_user_data.encrypt_identity_id

WHERE customers.uid=encrypt_user_data.uid;
