有大佬用 go 操作 doris 吗？问个入门问题

[zong400]

使用 xorm 和 gorm 操作 doris2.0 都不成功，看文档没有说支持 doris ，但是 doris 本身应该高度兼容 mysql 的吧，这些 orm 框架这么严格？还是代码上有问题？

xorm code:

func SelectAd() {
	engine := _init_db("10.22.xx", "9030", "abc")

	ad := new(FlowAdUrlStat)
	if _, err := engine.Where("opt_YYYYMMDD=?", 20240626).Get(ad); err != nil {
		log.Fatal(err)
	}

	fmt.Println(ad)
}

报错： 2024/06/27 10:55:37 Error 1105 (HY000): errCode = 2, detailMessage = Only support prepare SelectStmt point query now

gorm code:

	var ad FlowAdUrlStat

	stmt := db.Session(&gorm.Session{DryRun: true}).Where("opt_YYYYMMDD = ?", 20240626).Take(&ad).Statement
	fmt.Println(stmt.SQL.String()) 
	fmt.Println(stmt.Vars)         

	if err := db.Where("opt_YYYYMMDD = ?", 20240626).Take(&ad).Error; err != nil {
		log.Fatal(err)
	}

	fmt.Println(ad)

报错：

output:

蹲一个，我也很想知道

报错原因不是都写了吗?
OLAP 数据库不用 prepare 模式也能理解吧.

@MoYi123 试了 gorm 的 db.Raw 也是报错
```
if err := db.Raw("select * from flow_ad_url_stat limit 1").Scan(&ad).Error; err != nil {
log.Fatal(err)
}

[63.082ms] [rows:-] select * from flow_ad_url_stat limit 1
```

倒是 xorm 的可用，但是不能装进 struct ，感觉有些别扭。

result, err := engine.QueryString("select * from flow_ad_url_stat limit 1")

亲测，doris 从 1.x 升级到 2.0.10 ，gorm 使用正常
