在 SQL 中,可以使用 SELECT 語(yǔ)句中的 REPLACE 函數(shù)或者 SUBSTRING 函數(shù)來(lái)對(duì)敏感數(shù)據(jù)進(jìn)行脫敏處理。下面是一些示例:

  1. 使用 REPLACE 函數(shù)對(duì)手機(jī)號(hào)進(jìn)行脫敏:
SELECT REPLACE(phone_number, SUBSTRING(phone_number, 4, 4), '****') AS masked_phone_number
FROM customers;
  1. 使用 SUBSTRING 函數(shù)對(duì)郵箱地址進(jìn)行脫敏:
SELECT CONCAT(
    SUBSTRING(email, 1, 3),
    REPEAT('*', CHAR_LENGTH(email) - 7),
    SUBSTRING(email, CHAR_LENGTH(email) - 3)
) AS masked_email
FROM customers;
  1. 使用 REPLACE 函數(shù)對(duì)身份證號(hào)進(jìn)行脫敏:
SELECT CONCAT(
    SUBSTRING(id_number, 1, 6),
    REPEAT('*', CHAR_LENGTH(id_number) - 10),
    SUBSTRING(id_number, CHAR_LENGTH(id_number) - 3)
) AS masked_id_number
FROM customers;

通過(guò)以上方法,可以對(duì)敏感數(shù)據(jù)進(jìn)行脫敏處理,保護(hù)用戶的隱私信息。
