Python pyodbc“仅执行”

Question

我正在尝试使用pyodbc连接到本地MSSQL数据库，代码如下：

import pyodbc
conn = pyodbc.connect('Driver={ODBC Driver 17 for SQL Server};'
'Server=localhost;'
'Database=SampleDb;'
'Trusted_Connection=yes;')

cursor = conn.cursor()
cursor.execute = ('SELECT * FROM SampleDb.dbo.flights')

for row in cursor:
    print(row)

获取以下错误：

cursor.execute = ('SELECT * FROM SampleDb.dbo.flights')
AttributeError: 'pyodbc.Cursor' object attribute 'execute' is read-only

Answer 1

cursor.execute是一个函数，所以您只需要调用它，而不需要为它赋值。试试这个：

cursor.execute('SELECT * FROM SampleDb.dbo.flights')
