Go语言通过odbc驱动连接华为高斯数据库

1.下载odbc驱动

下载后安装psqlodbc_x64.msi

安装成功后可在odbc数据源中看到以下内容

2.测试odbc驱动

在用户dsn中选择添加

输入对应的连接内容点击test

如果显示以下内容则表示驱动正常可使用odbc连接高斯数据库

3.go 语言编写

其中依赖包需要使用命令安装

go get github.com/alexbrainman/odbc
go get github.com/axgle/mahonia
go get github.com/go-xorm/xorm
go get xorm.io/core

1）如果出现 golang.org/x/ 下包下载不下来的问题
