Vc access ado where 变量

char* zhuanhuan(std::string src) 
{
	char *dst = new char[255];
	int i; 
	int j=src.length();
	for(i=0;i <src.length();i++) 
		dst[i]=src[i]; 
	dst[i] = '\0';
	return dst;
}

openAccess();
	CString cmbParam = L"SelfImprovement";
	std::string a1=(CT2A)(cmbParam.GetBuffer());
	char buff[256]  = {0}; 
	sprintf(buff, "select * from tb_YCType where YCName = '%s' order by YCType desc",zhuanhuan(a1));
	m_pRecordset = m_pConnection->Execute(buff, &RecordsAffected, adCmdText);

这个算一个实用的方法吧！其他方法我还没用到，也欢迎有好方法的可以交流！
