cursor = conn.cursor() 确保将DataFrame转换为适合写入数据库的格式,如CSV文件。 代码语言:txt 复制 import pandas as pd # 创建DataFrame df = pd.DataFrame({'Column1': [1, 2, 3], 'Column2': ['A', 'B', 'C']}) #将DataFrame写入CSV文件 csv_file = 'data.csv' df.to_csv(csv_file...
因为我首先执行.fetchone()，然后用.fetchall()填充DataFrame，所以data没有包括第一个结果行。
我想发送一个大的 pandas.DataFrame 到运行 MS SQL 的远程服务器。我现在这样做的方法是将 data_frame 对象转换为元组列表,然后使用 pyODBC 的 executemany() 函数将其发送出去。它是这样的: import pyodbc as pdb list_of_tuples = convert_df(data_frame) connection = pdb.connect(cnxn_str) cursor = conn...
is sometimes empty (i.e. no data for query columns is available) and the query will fail with the aforementioned error. Moreover, this seems to happen at random. 90% of the time, the query will execute successfully and a dataframe is returned, then 10% of the time cursor.description is...

Hello, this project seems really useful, but sadly, I can't get it to work with MSSql over odbc. SqlAlchemy itself works fine with this setup, but I cannot execute a single query with ipython-sql. Maybe ipython-sql does a query without f...
