VFP OLEDB 9函数在表有插入、更新时未实现错误；删除触发器

当我试图插入到FoxPro表中时，收到了"函数未实现"错误，该表在表设置GUI中具有与其相关的插入触发器。使用vs2012，我在数据集中创建了一个表适配器。我添加了如下所示的更新声明。下面还列出了我的C#项目中执行插入/更新的代码。如果我从FoxPro表中删除相关的触发器，我可以成功地插入/更新。使用触发器，插入和更新会引发"函数未实现"错误。Select的工作很好。

请帮助

utacc FoxPro表具有触发器设置，用于插入、更新和删除相关的SQL Server表。在立柱底部插入触发器。

VS 2012表适配器插入命令

INSERT INTO utacc
                         (fcmodid, fcuname, fccompid, fcacclvl, fcscope)
VALUES        (?, ?, ?, ?, ?)

通过表适配器执行插入/更新的C#代码

using (var ta = new DataSet1TableAdapters.utaccTableAdapter())
{
    foreach (var u in lUsers.GetList().Where(x => x.selected))
    {
        foreach (var screen in lScreen.GetList().Where(x => x.selected))
        {
            if (ta.GetData()
                .Any(x => x.fccompid == _fccompid 
                    && x.fcmodid.Trim() == screen.fcmodid.Trim() 
                    && x.fcuname.Trim() == u.fcuname.Trim()))
                ta.Update(perm, screen.fcmodid, _fccompid, u.fcuname);
            else
                ta.Insert(screen.fcmodid, u.fcuname, _fccompid, perm, "P");
        }
    }
}

这些触发器是对SQL服务器表的插入
这是FoxPro触发
