while嵌套while只输出一次？菜鸟求帮助，谢谢

回复讨论(解决方案)

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

谢谢回复，不报错。

最里层的依赖第二层的查询结果： DM1='$row[KHDM]' and RQ='$endDate'
你怎么就知道一定会有？

我加了一个输出

$startDate = '2014-07-28';						$endDate   = $startDate ;						$nowDate =Date('Y-m-d',time());						$days=round((time()-strtotime("$startDate"))/86400);						while($endDate != $nowDate){				while($row=mssql_fetch_array($result)){										$result1=mssql_query("select sum(JE) from VW_SDLSMX where DM1='$row[KHDM]' and RQ='$endDate'",$conn);					echo $endDate;										while($rowlist1=mssql_fetch_array($result1)){												$rowlist1[RiQi]="$endDate";												$rowlist1[KHMC]=$row[KHMC];												$rowlist[1][]=$rowlist1;											}									}				    			$endDate = date('Y-m-d',strtotime($endDate.' +1 day'));    						}

结果都为2014-07-28，第二层就只循环了一次。

那不就说明 $result 只有一条记录吗？

额。。。第二个嵌套加个break

$startDate = '2014-07-28';						$endDate   = $startDate ;						$nowDate =Date('Y-m-d',time());						$days=round((time()-strtotime("$startDate"))/86400);						while($endDate != $nowDate){				while($row=mssql_fetch_array($result)){										$result1=mssql_query("select sum(JE) from VW_SDLSMX where DM1='$row[KHDM]' and RQ='$endDate'",$conn);										while($rowlist1=mssql_fetch_array($result1)){												$rowlist1[RiQi]="$endDate";												$rowlist1[KHMC]=$row[KHMC];												$rowlist[1][]=$rowlist1;											}					break;				}				    			$endDate = date('Y-m-d',strtotime($endDate.' +1 day'));    						}

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

$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);				while($row=mssql_fetch_array($result)){										$result1=mssql_query("select sum(JE) from VW_SDLSMX where DM1='$row[KHDM]' and RQ='$endDate'",$conn);										while($rowlist1=mssql_fetch_array($result1)){												$rowlist1[RiQi]="$endDate";												$rowlist1[KHMC]=$row[KHMC];												$rowlist[1][]=$rowlist1;											}				}				    			$endDate = date('Y-m-d',strtotime($endDate.' +1 day'));    						}

我被程序上了

输出的结果是

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

看这个：

你都堆到$rowlist[1]里了，所以你觉得只进行了一次。。。。。

3重while。。。难道不能联合查询去掉一层？跑起来不小心就是3次方啊

你有三重 while 是哪一重不对？
打印出相关变量看看

看这个：
$rowlist[1][]=$rowlist1;
你都堆到$rowlist[1]里了，所以你觉得只进行了一次。。。。。

如果都堆到1里的话那结果应该是最后一天的，而不是第一天的吧

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 '<br>';				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($result1); 					echo '<br>';					while($rowlist1=mssql_fetch_array($result1)){												$rowlist1[RiQi]="$endDate";												$rowlist1[KHMC]=$row[KHMC];											$rowlist[1][]=$rowlist1;											}				}				    			$endDate = date('Y-m-d',strtotime($endDate.' +1 day'));    						}

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)) {
