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;
