示例

from sqlalchemy import create_engine, MetaData, and_, or_, TIMESTAMP
Plugin.query.filter(and_(Plugin.job_name == job_name, or_(Plugin.group_id.is_(None), Plugin.group_id == delete_list[0]),
                        Plugin.plugin_name == delete_list[1], Plugin.plugin_version == delete_list[2],
                        Plugin.plugin_state == delete_list[3])).delete()

from django.db.models import Q
Plugin.objects.filter(
            Q(job_name=job_name, group_id=None, plugin_name=delete_list[1], plugin_version=delete_list[2],
              plugin_state=delete_list[3]) |
            Q(job_name=job_name, group_id=delete_list[0], plugin_name=delete_list[1],
              plugin_version=delete_list[2], plugin_state=delete_list[3])
        ).delete()
