Does the latest version not support Option single result?

提示异常：Some("系统异常:invalid type: map, expected a string")

你执行过cargo update 更新依赖了吗？

/// doc you can see https://rbatis.github.io/rbatis.io
#[sql("select max(id) from activity")]
async fn raw_sql(rb: &RBatis, delete_flag: &i32) -> String {
    impled!()
}

之前是4.5.11版本，cargo update更新了4.22版本后就不可以了，我看了更改记录，发现是4.20版本后decode.rs那里更改了导致的，然后就不支持解码Option这种类型了

嗯，已添加补丁代码，等下次新版本发布

It used to be version 4.5.11, but cargo update stopped working after it was updated to version 4.22. I looked at the change record and found that it was caused by changes in decode.rs after version 4.20, and then the decoding Option type was no longer supported. 

Well, the patch code has been added, waiting for the next release of the new version
