VC中用到ODBC数据库出现FROM子句语法错误？？？？？

void CContactDlg::INTree()
{
// 清空原有项目
m_tree.DeleteAllItems(); 

// 组查询
CString sql;
sql = "SELECT * FROM group ORDER BY ID DESC";
CDatabase db1;
CGrounp1 gi(&db1);
gi.Open(AFX_DB_USE_DEFAULT_TYPE, sql);

while(!gi.IsEOF())
{
// 插入组名
HTREEITEM hGroup = m_tree.InsertItem(gi.m_gname);
// 设置组ID
m_tree.SetItemData(hGroup, gi.m_ID);
// 查询组下成员
CString sql;
sql.Format("SELECT * FROM contactlist WHERE groupid = %d",gi.m_ID);
CDatabase db2;
CPeople1 people(&db2);
people.Open(AFX_DB_USE_DEFAULT_TYPE, sql);
   
HTREEITEM hPeople;
while(!people.IsEOF())
{
// 插入联系人
hPeople = m_tree.InsertItem(people.m_pname, hGroup);
// 设置联系人ID
m_tree.SetItemData(hPeople, people.m_ID);
people.MoveNext();
}
db2.Close();
gi.MoveNext();
}

db1.Close();
}
运行到gi.Open(AFX_DB_USE_DEFAULT_TYPE, sql);
就出现错误FROM子句语法错误
哪个高手帮帮忙？？？？？？？？？？？？？

group 是表名吗，改成其他的吧，和SQL的关键字冲突了。
