INSERT 和 UPDATE 语句无效,即使使用 autocommit=True

sql

当我运行它时,它们不会抛出任何错误。UPDATE并且INSERT INTO查询cikis不起作用,SQL Server 上没有发生插入或更新。

当我从 SSMS 表中检查时,我正在尝试更新并插入显示为正在执行。

giris功能“更新”正常工作。

代码中显示的值SlotAd = A1和其余值。

输出:

cikti
52 AT 533
52 AT 533
1 Arsive Eklendi.
1 slotu bosaldi.

gecmis, musaitlik bool

ucret int 和 rest varchar

除主键外,一切都允许空值。

autocommit=True不是连接字符串的一部分,它是传递给.connect()方法的附加关键字参数:

conn = pyodbc.connect(
    connection_string,
    autocommit=True
)

更新回复:问题编辑

不,这仍然不正确。你目前有

conn = pyodbc.connect('Driver={ODBC Driver 17 for SQL Server};'
                      'Server=DESKTOP-L68QR06\SQLEXPRESS;'
                      'Database=Otopark;'
                      'Trusted_Connection=yes;'
                      'autocommit=True'
)

但你需要的是

conn = pyodbc.connect('Driver={ODBC Driver 17 for SQL Server};'
                      'Server=DESKTOP-L68QR06\SQLEXPRESS;'
                      'Database=Otopark;'
                      'Trusted_Connection=yes;',
                      autocommit=True
)
