示例1: getStrongestStrength
void GetStrongestStrength::getStrongestStrength() {
/*SELECT
top 1 *
from GridFieldStrenthAddBaseNum
where gid = 2
ORDER BY
dbo.GridFieldStrenthAddBaseNum.GId ASC,
dbo.GridFieldStrenthAddBaseNum.GRSRP DESC*/
DataBase db;
//此处的判断条件有问题，gid和表中的行数并不对应，应该用id来进行索引
//因此改成了到grid表中，查找grid的个数来判断
int gRealSnrCount = DBHelper::queryTableInfoNum("Grid");
for(int id = 1;id <= gRealSnrCount;id++) {
if(852==id) {
int kk = 1;
}
string sqlString = "SELECT top 1 GId,AId,GRSRP from GridFieldStrenthAddBaseNum where gid = ";
sqlString.append(ChangeTypeTool::intToString(id));
