判断一字段相同记录总数是否大于1，应该怎么写的？`

string procName = "SELECT COUNT(*) FORM 表名 WHERE 条件";
//上面就当声明了SqlConnection
SqlCommand Cmd = new SqlCommand(procName,Conn)
int i = (int)Cmd.Exe...S .(忘了,就是那个返回首行首列的)
if(i > 0)
{
//ok
}
else
{
//no
}

SELECT id，count(*)
FROM [temp]
GROUP BY id
HAVING (COUNT(id) > 1)

找出记录数大于1的条目和它的次数
