C/C++ code:
GetDlgItem(IDC_EDIT_SEARCH)->GetWindowText(m_ipsearch);
CoInitialize(NULL);
_ConnectionPtr tempConn(__uuidof(Connection));
_RecordsetPtr tempRst(__uuidof(Recordset));
tempConn->ConnectionString="Provider=SQLOLEDB;driver=SQL Server;Server=10.11.1.166;Database=tongxue;uid=sa;Password=321456";
tempConn->Open("","","",adConnectUnspecified);
CString sql;
sql.Format("select servip from serviceip where instr(servip, '%s') > 0",m_ipsearch);
//sql.Format("select servip from serviceip where servip ='%s'",m_ipsearch);
tempRst = tempConn->Execute((_bstr_t)sql,0,adCmdText);
if(!tempRst->rsEOF)
{
m_servip=(TCHAR*)(_bstr_t)tempRst->GetFields()->GetItem("servip")->Value;
((CComboBox*)GetDlgItem(IDC_COMBO_IP))->AddString(m_servip);
tempRst->MoveNext();
}
else MessageBox("根本没这这号IP！");
m_ipsearch是一个CString类型数据（从一个edit 控件中获得）,serviceip是数据库中的一个存储IP表名，
servip是具体IP字段名；然后从表serviceip的servip中模糊查询m_ipsearch，并将查询到的结果添加到
一个combo控件中。
但程序在运行到tempRst = tempConn->Execute((_bstr_t)sql,0,adCmdText); 时报错：
Runtime Error!
select * from export where 品牌 is not null and 文章标题 like '%还要忍多久?丰田的'刹车'与'回归'%'
这句查询语句转义怎么写呀，请大家帮下忙，谢了
SQL code:
