# 一、在m1 mac下使用pyodbc (大坑，需要修改tsl协议版本，不建议使用)
参考官方文档 https://github.com/mkleehammer/pyodbc/wiki
```shell
# 1.安装odbc
brew update
brew install unixodbc
# 2.安装sqlserver linux驱动
brew tap microsoft/mssql-release https://github.com/Microsoft/homebrew-mssql-release
brew update
HOMEBREW_ACCEPT_EULA=Y brew install msodbcsql18 mssql-tools18
# 3.安装pyodbc
pip install --no-binary :all: pyodbc
```

```shell
# 查看配置文件路径
odbcinst -j
# 输出
unixODBC 2.3.12
DRIVERS............: /opt/homebrew/etc/odbcinst.ini

Description=Microsoft ODBC Driver 18 for SQL Server
Driver=/opt/homebrew/lib/libmsodbcsql.18.dylib
```


# 二、在m1 mac下使用pymssql 连接sqlserver
参考官方文档 https://pymssql.readthedocs.io/en/stable/freetds.html
```shell
# 1.安装freetds
brew install freetds
# 2.修改配置
vim /opt/homebrew/etc/freetds.conf
在[global]下添加
port = 1443
tds version = 7.0  
# 3.测试连接
tsql -H 172.16.1.2 -p 1433 -U sa -P atdPriME@Gy9# -D credit
#  返回以下情况说明连接成功
locale is "zh_CN.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
Setting credit as default database in login packet
```
freetds连接成功后安装pymssql
```shell
pip install pymssql
```
