【问题描述】:
当我尝试在 python 中通过 Pymssql 连接到 Azure 数据库时,我遇到了这个错误:
pymssql.OperationalError: (20002, 'DB-Lib error message 20002, severity 9:\nAdaptive Server connection failed (iprice-bi.database.windows.net:1433)\n')
我通过tsql命令连接数据库:
tsql -H server -p 1433 -U username -P password
locale is "en_US.UTF-8"
语言环境字符集是“UTF-8” 使用默认字符集“UTF-8” 1> 选择@@版本 2> 去
Microsoft SQL Azure (RTM) - 12.0.2000.8

我还检查了 freetds.conf 以确保我使用的是正确的版本。
[global]
# TDS protocol version
tds version = 7.0
dump file = /tmp/freetds.log
dump file append = yes
日志文件的结果也没有给出任何线索。

有没有人遇到这样的问题或者可以给我一些解决的建议?!
