源码来源于官方安装包，驱动包的路径： `dmdbms/drivers/go/dm-go-driver.zip` , 详见说明： [Go 数据库接口](https://eco.dameng.com/document/dm/zh-cn/app-dev/go-go.html)
## DataSourceName
```
dm://username:password@host:port?schema=schemaName[&logLevel=debug&sslFilesPath&=pathValue&timeout=timeoutValue¶m1=value1&...¶mN=valueN]
```
`dm://SYSDBA:SYSDBA@localhost:5236`
## Example
`go get github.com/ganl/go-dm@v1.2.193`
PS: 8.1.2.192 / 8.2.2.192 官方未改驱动构建32位，编译报错： constant 4294967295 overflows int
