Question

pyodbc是否有执行标量函数？

类似于.net中的sql库执行标量？

Answer 1

pyodbc游标有fetchone()方法。

cursor.execute("select user_name from users where user_id=?", userid)
row = cursor.fetchone()
if row:
    print row.user_name 
    # or print row[0]

Answer 2

我不这么认为，但sqlalchemy确实如此（除了使用ORM等，它还可以用作DB API库的方便的更高级别接口）。举个例子：

import sqlalchemy

# using mssql as an example because sqlalchemy uses pyodbc as the default driver for MS Sql Server
engine = sqlalchemy.create_engine("mssql://myserver/mydb")
# first column of first row is returned
username = engine.scalar("select username from users where userid = 1")
