python pandas读取sqlserver数据库

使用pandas读取SQL Server数据库可以通过read_sql()方法实现。首先，需要确保已经连接好数据库。可以参考以下代码示例：

import pandas as pd

# 假设已经连接好数据库，可以直接使用conn变量
sql = "select * from 要查询的表格"
df0 = pd.read_sql(sql, conn)
df = pd.DataFrame(df0)

以上代码会将查询结果读取到一个DataFrame中，然后可以对数据进行进一步处理和分析。这样可以确保数据以正确的编码显示和处理。<em>1</em><em>2</em><em>3</em>
