你这个报错不
你有三重 while 是哪一重不对?
打印出相关变量看看

7月28到8月7号都是有内容的,但是就只循环一次
echo mssql_num_rows($result);
加载 while($row=mssql_fetch_array($result)){ 前面
真不知道是你写程序,还是程序写你

num 都是对的,应该不会只循环了一次,楼主是怎么知道只循环了一次的?
while($endDate != $nowDate){ echo mssql_num_rows($result); //看看这里 while($row=mssql_fetch_array($result)){ $result1=mssql_query("select sum(JE) from VW_SDLSMX where DM1='$row[KHDM]' and RQ='$endDate'",$conn); echo mssql_num_rows($result1); //再看看这里

你按我#14的建议做了吗?
看看结果好吗
不知道你外层的查询语句是什么样的
通常只要不是树状数据,只要关联查询就可解决问题
少了一重循环,就少了一半的出错几率

我只建议你 2 处 echo, 后面的 11个 20 是哪里来的?
也不想想:为什么 20条记录在内层只出 11 个 20
也不断一下行,连续的数字,你知道谁对谁吗?
20 应表示外层有 20 条记录
20 个 1 表示每条记录对应有一条记录($result1=mssql_query("select sum(JE) from VW_SDLSMX where DM1='$row[KHDM]' and RQ='$endDate'",$conn);)
所以最终结果应有 20 个元素,你#4打印的不正好是 20 个吗?

$startDate = '2014-07-28'; $endDate = $startDate ; $nowDate =Date('Y-m-d',time()); $days=round((time()-strtotime("$startDate"))/86400); while($endDate != $nowDate){ echo mssql_num_rows($result); echo '

明白了,后面的 20 是 while($endDate != $nowDate) 循环输出的
其实你的代码本身并没有多大问题,只是忽略了这样一个事实:
while($row=mssql_fetch_array($result)) 将读空结果集 $result
再次进入就没得读了,所以你需要回绕结果集 mssql_field_seek
即
mssql_field_seek($result, 0);while($row=mssql_fetch_array($result)) {

怎么又弄错了:{
代码的第9行改为
mssql_data_seek($result, 0);while($row=mssql_fetch_array($result)) {不是
