我正在尝试将来自用户输入的数据插入到已设置的SQLite数据库中。这是我当前编写的代码：

var stmt: OpaquePointer?
let queryString = "INSERT INTO entries (id, name, email, avatar) VALUES (NULL,?,?,?)"

if(sqlite3_prepare_v2(db, queryString, -1, &stmt, nil) == SQLITE_OK){
        sqlite3_bind_text(stmt, 1, strName, -1, nil)
        sqlite3_bind_text(stmt, 2, strEmail, -1, nil)
        sqlite3_bind_text(stmt, 3, "batman", -1, nil)
    }

else{
        let errMsg = String(cString: sqlite3_errmsg(db)!)
        print("error preparing insert: \(errMsg)")
        return
}

从文本字段中提取了strName和strEmail。当我在另一个视图中查询此数据时，由于某种原因“蝙蝠侠”已插入第二列而不是用户输入。这是选择查询：

let queryString = "SELECT * FROM entries"
var stmt: OpaquePointer?

if sqlite3_prepare_v2(db, queryString, -1, &stmt, nil) != SQLITE_OK{
        let errmsg = String(cString: sqlite3_errmsg(db)!)
        print("error preparing select: \(errmsg)")
        return …
