Python connects to the SQL Server database

Method One:

1, need to install pymssql

　　pip install pymssql

2. Connection code:

import pymssqlconn=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、删除、更新语句切记要写提交命令con.commit()print (cur.fetchall())cur.close()conn.close()

The following is the Django action method two (Django operation):

1, install the necessary components:

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

2, modify the settings.py 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‘,        },    }}

Method Three (Django):

1. You need to install SQL Server Management Studio or the manually install Microsoft Data Access components (MDAC) program.

2. Install Django-mssql and Pywin32:

　　pip install django-mssql

3, modify the settings.py 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为‘SQLCLI10‘时若有问题，可改成‘SQLOLEDB‘ ，反之亦然。            ‘provider‘: ‘SQLOLEDB‘, # Have also tried ‘SQLCLI11‘ and ‘SQLOLEDB‘            ‘extra_params‘: ‘DataTypeCompatibility=80‘        },    }}

Method Four (Django):

1. Installation of Django-pyodbc-azure and PYODBC

    pip install django-pyodbc-azure pyodbc

2, modify the settings.py 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 poolingDATABASE_CONNECTION_POOLING = False
