我试图通过重用预处理语句、使用事务和参数化查询来提高保存代码的效率。但是，每当我运行保存代码时，表中只有一条记录。我认为这与sqlite3_step的放置位置有关。
但我也希望有其他的眼睛来检查我的代码，让我知道我做的事情是否正确;我在任何地方都找不到这样做的例子，所以它是一个混乱的大约六个论坛帖子和堆栈溢出主题，我在各种主题上找到：

//Planet Data

//Delete previous save data
dData("Generated_Planets", bErrors);

if (plData.size() > 0)
{
    sqlite3_exec(dBase, "BEGIN TRANSACTION", NULL, NULL, &error);

    sqlStr = "Insert Into Generated_Planets (ID, Name, Affiliation, Disposition, Race, Player_Owned, Is_Destroyed, EKS, Planet_Size, Current_Pop, Max_Pop) Values (?,?,?,?,?,?,?,?,?,?,?);";

    if (sqlite3_prepare_v2(dBase, sqlStr.c_str(), sqlStr.size(), &statement, 0) == SQLITE_OK)
    {
        cout << "Saving planet data";
        //Save new data
        for (i = 0; i <= plData.size(); i++)
        {
            if (i == plData.size())
            {
                finalize(statement, bErrors);
            }

            else
            {
                sqlI1 = plData.at(i).pID;
                sqlS1 = plData.at(i).pName;
