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
你这个报错不
谢谢回复,不报错。$rowlist

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

你都堆到$rowlist[1]里了,所以你觉得只进行了一次。。。。。

打印出相关变量看看
打印$rowlist结果如下:
array(1) { [1]=> array(20) { [0]=> array(4) { [0]=> string(8) "164.0000" ["computed"]=> string(8) "164.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "南京*" } [1]=> array(4) { [0]=> string(9) "4512.0000" ["computed"]=> string(9) "4512.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "南京商厦" } [2]=> array(4) { [0]=> string(9) "1207.0000" ["computed"]=> string(9) "1207.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "南京山百" } [3]=> array(4) { [0]=> string(9) "2985.0000" ["computed"]=> string(9) "2985.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "南京湖百" } [4]=> array(4) { [0]=> string(9) "5327.0000" ["computed"]=> string(9) "5327.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "南京太平" } [5]=> array(4) { [0]=> string(9) "1360.0000" ["computed"]=> string(9) "1360.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "南京九龙" } [6]=> array(4) { [0]=> string(8) "700.0000" ["computed"]=> string(8) "700.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "南京长发" } [7]=> array(4) { [0]=> string(9) "4152.0000" ["computed"]=> string(9) "4152.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(15) "南京新城市" } [8]=> array(4) { [0]=> string(9) "2633.0000" ["computed"]=> string(9) "2633.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(15) "湖南路专卖" } [9]=> array(4) { [0]=> string(10) "10672.0000" ["computed"]=> string(10) "10672.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "江宁苏果" } [10]=> array(4) { [0]=> string(9) "2323.0000" ["computed"]=> string(9) "2323.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "溧水苏果" } [11]=> array(4) { [0]=> string(8) "750.0000" ["computed"]=> string(8) "750.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(15) "瑞金路特惠" } [12]=> array(4) { [0]=> string(9) "1194.0000" ["computed"]=> string(9) "1194.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "桥北华联" } [13]=> array(4) { [0]=> string(9) "1530.0000" ["computed"]=> string(9) "1530.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "六合苏果" } [14]=> array(4) { [0]=> string(9) "1540.0000" ["computed"]=> string(9) "1540.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(15) "三牌楼特惠" } [15]=> array(4) { [0]=> string(9) "8629.0000" ["computed"]=> string(9) "8629.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "南京新百" } [16]=> array(4) { [0]=> string(9) "1399.0000" ["computed"]=> string(9) "1399.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(12) "南京德基" } [17]=> array(4) { [0]=> string(9) "1218.0000" ["computed"]=> string(9) "1218.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(15) "江宁万尚城" } [18]=> array(4) { [0]=> string(9) "2772.0000" ["computed"]=> string(9) "2772.0000" ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(15) "瑞金路专卖" } [19]=> array(4) { [0]=> NULL ["computed"]=> NULL ["RiQi"]=> string(10) "2014-07-28" ["KHMC"]=> string(18) "江宁富腾奥莱" } }}
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 '

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($result)) {不是
mssql_field_seek($result, 0);
while($row=mssql_fetch_array($result)) {
