TEXT字段类型报错

https://eco.dameng.com/community/article/765cc5688e65be1a5be6bb2fdc0410b8 使用go语言遇到读取text类型报错的问题。报错信息： sql: Scan error on column index 9, name “resource_ids”: unsupported Scan, storing driver.Value type *dm.DmClob into type *string Golang 在表字段类型为TEXT时，解析为string类型失败; go语言是grom框架比较MySQL和DM8中jdbc返回类型，mysql的做法是转成[]uint8，达梦里面是转成DmClob,所以导致报错，最新的处理方式是增加一个配置项，兼容MySQL这种用法。 1、连接串的地方增加localhost:5236?compatibleMode=mysql 2、使用最新的go驱动包。按照官网的说法，获取这个新的包，仍不对呢
