Python: 在数据库 'master' 中创建 TABLE 权限被拒绝

Question

我正在尝试使用我发现的方法从 NAV 获取 Field no： https://redthree.com/nav-object-field-and-option-numbers-in-the-sql-server-database/?utm_source=rss&utm_medium=rss&utm_campaign=nav-object-field-and-option-numbers-in-the-sql-server-database

而且效果很好！直到我必须将数据返回到 MSSQL 数据库我在最后一行得到以下异常：

(pyodbc.ProgrammingError) ('42000', "[42000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]CREATE TABLE permission denied in database 'master'. (262) (SQLExecDirectW)")

奇怪的是，我没有尝试连接到 master 数据库，而是我所在的数据库 db.owner 并且我有权创建表...

我正在使用 Visual studio 和 Python 3.9

下面是我绑定的代码运行

# here we take our dataframes and put them into SQL
dfNAVFieldNames.to_sql("NAVFieldNames",con=engine,schema=Schema,if_exists="append",index=False)
dfNAVFieldOptions.to_sql("NAVFieldOptions",con=engine,schema=Schema,if_exists="append",index=False)

我希望有人能给我指出正确的方向！ :)

我找到了解决方案当我应该使用 SQL “Server Native Client 11.0”时，我正在使用驱动程序“ODBC Driver 17 for SQL Server” 我在我的案例中工作:)
