实例

import pymssql

# 获取连接
conn = pymssql.connect(‘127.0.0.1‘, ‘sa‘, ‘ddh123‘, "aaa")

# 获取游标
cursor = conn.cursor()

# 执行sql
sql = ‘‘‘
    insert into t_user 
      (username,password,age,height)
    values 
      (‘alice2‘, ‘1213‘, 19, 172)  
‘‘‘
num = cursor.execute(sql)  # 为占位符%s赋值

# 提交事务
conn.commit()

# 关闭资源
cursor.close()
conn.close()

from os import getenv
import pymssql

server = getenv("PYMSSQL_TEST_SERVER")
user = getenv("PYMSSQL_TEST_USERNAME")
password = getenv("PYMSSQL_TEST_PASSWORD")

conn = pymssql.connect(server, user, password, "tempdb")
cursor = conn.cursor()
cursor.execute("""
IF OBJECT_ID(‘persons‘, ‘U‘) IS NOT NULL
    DROP TABLE persons
CREATE TABLE persons (
    id INT NOT NULL,
    name VARCHAR(100),
    salesrep VARCHAR(100),
    PRIMARY KEY(id)

""")
cursor.executemany(
    "INSERT INTO persons VALUES (%d, %s, %s)",
    [(1, ‘John Smith‘, ‘John Doe‘),
     (2, ‘Jane Doe‘, ‘Joe Dog‘),
     (3, ‘Mike T.‘, ‘Sarah H.‘)])
# you must call commit() to persist your data if you don‘t set autocommit to True
conn.commit()

cursor.execute(‘SELECT * FROM persons WHERE salesrep=%s‘, ‘John Doe‘)
row = cursor.fetchone()
while row:
    print("ID=%d, Name=%s" % (row[0], row[1]))
    row = cursor.fetchone()

conn.close()

使用迭代器

conn = pymssql.connect(server, user, password, "tempdb")
cursor = conn.cursor()
cursor.execute(‘SELECT * FROM persons WHERE salesrep=%s‘, ‘John Doe‘)

for row in cursor:
    print(‘row = %r‘ % (row,))

conn.close()
