Heim > Artikel > Backend-Entwicklung > 同一条sql,php程序执行的结果和数据库执行的结果不一样,求解
输出sql和结果集的代码如下
$sql=$sql1.$sql_initbest;echo $sql;//initRows4($start_date,$end_date,$objActSheet);//$months=getIntMonth($start_date,$end_date1);//$count_1=3*$months+3;//每个月有3列//echo $sql1.$sql_initbest;$query = mssql_query($sql);//$c=0;//$arr=Array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');//$count_4=0;//月份计数器//$n=4;//$arr1=array();while($row=mssql_fetch_array($query)){ print_r($row); echo "<br><br>";
数据是在时时更新的吗?
1)贴出sql,拿到mysql编辑器执行看看。
2)在程序处输出sql,并且打印结果集看看。

都在帖子上有,用的是ms-sql数据库

class2 为 B、C 时的相应值都不一样
你能确定表数据没有变化吗?
数据是在时时更新的吗?
数据不是实时更新的
class2 为 B、C 时的相应值都不一样
你能确定表数据没有变化吗?
class2为B、C时值不一样;能确定表数据没变化
这下悲剧鸟....有好几个都是同样的sql用程序和直接在数据库编译器中执行的结果不一样( 确定是同样的sql,确定数据库不是实时更新的)
测试如下 代码:
<?phpinclude_once 'DB_connmssql.php';$sql="select class2 ,January2014_Number_stores,January2014_Quantity_sold, January2014_qn=January2014_Quantity_sold/January2014_Number_stores,February2014_Number_stores,February2014_Quantity_sold, February2014_qn=February2014_Quantity_sold/February2014_Number_stores,March2014_Number_stores,March2014_Quantity_sold, March2014_qn=March2014_Quantity_sold/March2014_Number_stores from (select db_bi.class2,January2014_Number_stores = count(distinct case when left(db_bi.qsq,6) <='201401' then db_bi.dbno_bi else null end),January2014_Quantity_sold = SUM(case left(CMD..cmd_xjjx_sale.outdate,6) when '201401'then CMD..cmd_xjjx_sale.nb else 0 end),February2014_Number_stores = count(distinct case when left(db_bi.qsq,6) <='201402' then db_bi.dbno_bi else null end),February2014_Quantity_sold = SUM(case left(CMD..cmd_xjjx_sale.outdate,6) when '201402'then CMD..cmd_xjjx_sale.nb else 0 end),March2014_Number_stores = count(distinct case when left(db_bi.qsq,6) <='201403' then db_bi.dbno_bi else null end),March2014_Quantity_sold = SUM(case left(CMD..cmd_xjjx_sale.outdate,6) when '201403'then CMD..cmd_xjjx_sale.nb else 0 end)from db_bi,CMD..cmd_xjjx_sale,BI_Product_Informationwhere db_bi.dbno = CMD..cmd_xjjx_sale.storeand BI_Product_Information.colthno = CMD..cmd_xjjx_sale.colthnoand CMD..cmd_xjjx_sale.outdate>='2014-01'and CMD..cmd_xjjx_sale.outdate<='2014-04'and charindex( '已撤',db_bi.names) = 0 and db_bi.class2 in ('A','B','C','O') and closeif <> 1 and flags_bi in('1','2','3','4') and CMD..cmd_xjjx_sale.endprice <> 0group by db_bi.class2) aorder by class2";$query = mssql_query($sql);while($row=mssql_fetch_array($query)){ print_r($row); echo "<br><br>";}?>
那你检查一下是否为同一的数据库
不要 php 查询的是在用的库(数值大些),而控制台查询的是备份的库

确定是同一个数据库,而且发现了几个类似的问题,同样的sql用程序执行和直接在控制台执行的结果不一样。

找到原因了,经过对比发现sql中这一句
and charindex( '已撤',db_bi.names) = 0
解决了把‘已撤’改为
". iconv('utf-8', 'gbk', '已撤')."
我看你里面有时间条件,是条件不一样吧

斑竹 请教另外个问题
在导出成excel文件时我用number_format函数对数据进行了处理,然后在最后求和是调用了excel的sum函数ru
$objActSheet->setCellValue($arr[$j].$n,"=SUM($x1:$x2)");
不要用 number_format 函数格式化数据
而应该用单元格格式来控制,比如
$sheet->getStyle('D6') ->getNumberFormat() ->setFormatCode('#,##0');
