rana/ora.v4连接oracle的示例代码报错 (srvCfg := ora.SrvCfg{Dblink: "orcl"} env.OpenSrv(&srvCfg) )
jimyokl · · 2791 次点击不好意思哈,再问一下,我怎么看到的https://github.com/rana/ora 里面的代码有&的:
https://github.com/rana/ora
和
sc := &ora.SrvCfg{Dblink: "orcl"}
srv, err := env.OpenSrv(sc)
谢谢了哈,请大佬再帮忙看看

我觉得官方的代码应该没问题,代码链接:https://github.com/rana/ora
改为 env.OpenSrv(srvCfg) 后编译能通过,但运行时报错:
