python dataset 庫用法

db = dataset.connect(url='mysql://user:password@host:port/db?charset=utf8')

# 查詢一行，支持多個關鍵字搜索，中間以逗號隔開
res = db["instance"].find_one(Id = 6057)

#查詢多行

res1 = db["instance"].find()

res1 為列表，每個元素為一個字典

acc_ins = {}
for k,v in res.items():
    acc_ins[k] = v
acc_ins['Id'] = 26057
acc_ins['Name'] = 'aaa'
acc_ins['tanceId'] = 'ACCTINS_2663'

#用字典插入數據

db["instance"].insert(acc_ins)

# 存在則更新不存在插入，ID為26057，Name的值，ensure = False 

db["instance"].upsert(dict(Id=26057, Name='dddddeeeee'),['Id'] ,ensure = False)
res = db["instance"].find_one(Id = 26057)
print(res)
