where = where or {}
if uuid:
where['uuid'] = uuid
q = Query(cls).select(["count(*)"]).where(where).limit(1)
sql, where = q.query()

# 需要导入模块: from query import Query [as 别名]
# 或者: from query.Query import query [as 别名]
def save(self):
# If it doesn't have an ID (Either nonexistant or not set), then call the
# create() method to do an INSERT instead of an UPDATE.
