使用pymysql和sqlalchemy在mysql中創建表

我在使用python 3.3在mysql中創建表時遇到問題。我正在使用Pymysql-0.15和SQLAlchemy。使用pymysql和sqlalchemy在mysql中創建表

當前我在Pythonwin中運行此代碼並具有以下輸出。

from sqlalchemy imort * 

    from sqlalchemy import * 
    import pymysql 
    engine = create_engine("mysql+pymysql://admin:[email protected]/dbeerste") 

    engine = create_engine("mysql+pymysql://admin:[email protected]/dbeerste") 
    metadata = MetaData(bind=engine) 
    users_table = Table('users', metadata, Column('id', Integer, primary_key=True), Column('name', String(40)), Column('age', Integer), Column('password', String),) 
    metadata.create_all(engine) 

Traceback (most recent call last): 
    File "<interactive input>", line 1, in <module>

請annyone幫我解決這個問題嗎？

您的代碼看起來不錯，但MySQL要求您指定密碼字段的長度。修復之後，我能夠對MySQL數據庫執行查詢沒有問題。如果它仍然不適合你，那麼這是數據庫服務器或驅動程序的問題，所以你可以嘗試重新安裝這些東西。

我們也試過，但我們遇到了同樣的錯誤。問題是我們能夠使用mysqlconector conectionstring插入數據庫，但我們想使用pymysql。 engine = create_engine（「mysql + mysqlconnector：// admin：[email protected]/dbeerste」）感謝您的快速回復:) – GertV 2013-02-21 09:20:18
