PG脱敏-查询语句中带有别名脱敏处理

[learn0208]

修复了PG查询语句中带有别名字段时不能脱敏的处理逻辑。
目前使用没啥问题。
此脱敏方法一样适合于oracle

也是辛苦了, 我之前的 brute mask 就是因为不想去处理sql里的别名这些东西, 做的全字段脱敏

这边需求，没辙啊，只能硬着头皮来。
看你代码，脱敏对mysql这里有个简单的优化。先判断是否存在实例的脱敏规则，不然这个消耗有点大。
我这边是这么干的。前面加了个简单判断

def data_masking(instance, db_name, sql, sql_result):
    """脱敏数据"""
    try:
        # 如果实例没有配置脱敏规则, 跳过脱敏环节
        masking_columns = DataMaskingColumns.objects.filter(instance=instance, active=True)
        if not masking_columns:
            return sql_result
