How to update sqlite using go without other libraries
问题
嗨，我一整天都在为在Go中使用SQLite更新用户数据库中的secretQuestion和secretAnswer而苦恼，我在我的实际文件中有以下代码：
r.ParseForm()id := r.URL.Query().Get("id")secretQuestion := r.Form.Get("question")secretAnswer, _ := bcrypt.GenerateFromPassword([]byte(r.Form.Get("answer")), 14)database.Db, err = sql.Open("sqlite3", "./database/database.db")if err != nil {panic(err)}result, _ := database.Db.Prepare("UPDATE users SET secretQuestion = ?,secretAnswer = ? WHERE id=?")result.Exec(secretQuestion, secretAnswer, id)
我尝试了很多方法，但没有找到一个可行的方法。像这个例子一样编译没有错误（通过恢复错误进行尝试），但在打开我的数据库后，secretQuestion和secretAnswer仍然为空。请注意，我已经检查过它们不是空值。
非常感谢您的帮助！我不太习惯使用论坛，如果需要添加其他信息，请随时告诉我。

Hi ive been in trouble all the day finding a way to update secretQuestion and secretAnswer in my user database in sqlite using go, what i have in my actual file is:
r.ParseForm()id := r.URL.Query().Get("id")secretQuestion := r.Form.Get("question")secretAnswer, _ := bcrypt.GenerateFromPassword([]byte(r.Form.Get("answer")), 14)//database.Db, err = sql.Open("sqlite3", "./database/database.db")if err != nil {panic(err)}//result, _ := database.Db.Prepare("UPDATE users SET secretQuestion = ?,secretAnswer = ? WHERE id=?")result.Exec(secretQuestion, secretAnswer, id)
I didnt found a single way that work and ive tried a good amount, those like this one compile and dont give error (tryed by recovering the err) but after opening my database secretQuestion and secretAnswer are still nill, note that what I gave them is not nill already checked that.
Thanks per advance for the help ! I'm not used to used forum so feel free to tell me if I need to add something.

这对我来说没问题：
package mainimport ("database/sql"_ "github.com/mattn/go-sqlite3")func main() {d, e := sql.Open("sqlite3", "file.db")if e != nil {panic(e)}defer d.Close()d.Exec("UPDATE artist_t SET check_s = ? WHERE artist_n = ?", "2021-05-20", 42)}

This works for me:
package mainimport ("database/sql"_ "github.com/mattn/go-sqlite3")func main() {d, e := sql.Open("sqlite3", "file.db")if e != nil {panic(e)}defer d.Close()d.Exec("UPDATE artist_t SET check_s = ? WHERE artist_n = ?", "2021-05-20", 42)}
