python連接SQL Server數據庫

sql ase ons cursor ide ant all win azure

方法一:

1、需要安裝pymssql

  pip install pymssql

2、連接代碼:

import pymssql

conn=pymssql.connect(host=‘127.0.0.1‘,user=‘user‘,password=‘password‘,database=‘MyDB‘)
cur=conn.cursor()
cur.execute(‘select * from table1‘)
#如果是插入、刪除、更新語句切記要寫提交命令con.commit()
print (cur.fetchall())
cur.close()
conn.close()

以下為Django中操作

方法二(Django操作):

1、安裝必要的組件:

  pip install django-sqlserver django-pytds pyodbc django-pyodbc pypiwin32  

2、修改settings.py的DATABASES:

DATABASES = {
    # ‘default‘: {
    #     ‘ENGINE‘: ‘django.db.backends.sqlite3‘,
    #     ‘NAME‘: os.path.join(BASE_DIR, ‘db.sqlite3‘),
    # }
    ‘default‘: {
        ‘ENGINE‘: ‘sqlserver‘,
        ‘NAME‘: ‘MyDB‘,
        ‘HOST‘: ‘127.0.0.1‘,
        ‘PORT‘: ‘1433‘,
        ‘USER‘: ‘user‘,
        ‘PASSWORD‘: ‘password,
        ‘OPTIONS‘: {
            ‘DRIVER‘: ‘SQL Server Native Client 10.0‘,
        },
    }
}

方法三(Django):

1、需要安裝 SQL Server Management Studio 或者 manually install Microsoft Data Access Components (MDAC)程序。

2、安裝django-mssql和pywin32:

  pip install django-mssql

3、修改settings.py的DATABASES:

DATABASES = {
    # ‘default‘: {
    #     ‘ENGINE‘: ‘django.db.backends.sqlite3‘,
    #     ‘NAME‘: os.path.join(BASE_DIR, ‘db.sqlite3‘),
    # }

       ‘default‘: {
        ‘NAME‘: ‘MyDB‘,
        ‘ENGINE‘: ‘sqlserver_ado‘,
        ‘HOST‘: ‘127.0.0.1‘,
        ‘USER‘: ‘user‘,
        ‘PASSWORD‘: ‘password‘,
        ‘OPTIONS‘: {
            #provider為‘SQLCLI10‘時若有問題,可改成‘SQLOLEDB‘ ,反之亦然。
            ‘provider‘: ‘SQLOLEDB‘, # Have also tried ‘SQLCLI11‘ and ‘SQLOLEDB‘
            ‘extra_params‘: ‘DataTypeCompatibility=80‘
        },
    }
}

方法四(Django):

1、安裝django-pyodbc-azure和pyodbc

    pip install django-pyodbc-azure pyodbc

2、修改settings.py的DATABASES:

DATABASES = {
    ‘default‘: {
         ‘ENGINE‘: ‘sql_server.pyodbc‘,
         ‘NAME‘: ‘MyDB‘,
         ‘USER‘: ‘user‘,
         ‘PASSWORD‘: ‘password‘,
         ‘HOST‘: ‘127.0.0.1‘,
         ‘PORT‘: ‘‘,
          ‘OPTIONS‘: {
              ‘driver‘:‘SQL Server Native Client 11.0‘,
              ‘MARS_Connection‘: True,
         },
     },
}
# set this to False if you want to turn off pyodbc‘s connection pooling
DATABASE_CONNECTION_POOLING = False
