Question

我正在寻找一些帮助来运行这个查询每个月。

$params = array(&$_POST['query']); 

$SQL1 = "SELECT SUM(Income) AS OrderTotal 
FROM SalesDB 
WHERE 
SalesDB.[Posting Date] <= '2013-01-01' AND 
SalesDB.[Posting Date] >= '2013-01-31'"; 

$options = array("Scrollable" => SQLSRV_CURSOR_KEYSET); 
$getProducts1 = sqlsrv_query($conn, $SQL1, $params, $options); 
if ($getProducts1 === false) 
die(var_dump(sqlsrv_errors())); 

while ($row = sqlsrv_fetch_array($getProducts1, SQLSRV_FETCH_ASSOC)) 
{ 
$row['OrderTotal']; 
} 

以这种方式，我得到了1月份的总收入。有没有办法做一个循环，所以它在今年每个月都会运行一个查询？

所以我没有做这样笨的办法：

$params = array(&$_POST['query']); 

    $SQL1 = "SELECT SUM(Income) AS OrderTotal 
    FROM SalesDB 
    WHERE 
    SalesDB.[Posting Date] <= '2013-01-01' AND 
    SalesDB.[Posting Date] >= '2013-01-31'"; 

    $options = array("Scrollable" => SQLSRV_CURSOR_KEYSET); 
    $getProducts1 = sqlsrv_query($conn, $SQL1, $params, $options); 
    if ($getProducts1 === false) 
    die(var_dump(sqlsrv_errors())); 

$SQL2 = "SELECT SUM(Income) AS OrderTotal 
    FROM SalesDB 
    WHERE 
    SalesDB.[Posting Date] <= '2013-02-01' AND 
    SalesDB.[Posting Date] >= '2013-02-28'"; 

    $options = array("Scrollable" => SQLSRV_CURSOR_KEYSET); 
    $getProducts2 = sqlsrv_query($conn, $SQL2, $params, $options); 
    if ($getProducts2 === false) 
    die(var_dump(sqlsrv_errors())); 

    while ($row1 = sqlsrv_fetch_array($getProducts1, SQLSRV_FETCH_ASSOC) AND $row2 = sqlsrv_fetch_array($getProducts2, SQLSRV_FETCH_ASSOC)) 
    { 
    echo $row1['OrderTotal']; 
echo $row2['OrderTotal']; 

    } 

Answer 1

您需要使用GROUP BY。此查询将得到所有的收入总和为2013，按照日期顺序：

$params = array(&$_POST['query']); 

$SQL1 = "SELECT SUM(Income) AS OrderTotal 
FROM SalesDB 
WHERE 
YEAR(SalesDB.[Posting Date]) = '2013' 
GROUP BY MONTH(SalesDB.[Posting Date]) 
ORDER BY MONTH(SalesDB.[Posting Date])"; 

$options = array("Scrollable" => SQLSRV_CURSOR_KEYSET); 
$getProducts = sqlsrv_query($conn, $SQL1, $params, $options); 
if ($getProducts === false) 
die(var_dump(sqlsrv_errors())); 

while ($row = sqlsrv_fetch_array($getProducts, SQLSRV_FETCH_ASSOC)) 
{ 
    echo $row['OrderTotal']; 
} 

要显示0而不是NULL的日期没有任何数据，则可以COALESCE结果：

$SQL1 = "SELECT COALESCE(0,SUM(Income)) AS OrderTotal 
     FROM SalesDB 
     WHERE YEAR(SalesDB.[Posting Date]) = '2013' 
     GROUP BY MONTH(SalesDB.[Posting Date]) 
     ORDER BY MONTH(SalesDB.[Posting Date])"; 

Answer 2

您可以按个月的记录，但你需要为了得到日期的月份值使用MONTH()。

SELECT MONTH(SalesDB.[Posting Date]) MonthNo, 
     DATENAME(month, SalesDB.[Posting Date]) MonthName, 
     SUM(Income) OrderTotal 
FROM SalesDB 
WHERE SalesDB.[Posting Date] BETWEEN '2013-01-01' AND '2013-12-31' 
GROUP BY MONTH(SalesDB.[Posting Date]), 
      DATENAME(month, SalesDB.[Posting Date]) 
ORDER BY MonthNo ASC 

Answer 3

如果我正确地理解了你，你正试图按月和年取得SUM（收入）？

而你的领域是：SalesDB。[发布日期]？

这是我会怎么做：

$sql = "SELECT SUM(Income) AS OrderTotal, YEAR(alesDB.[Posting Date]) AS year, MONTH(alesDB.[Posting Date]) AS month 
FROM SalesDB 
GROUP BY YEAR(alesDB.[Posting Date]), MONTH(alesDB.[Posting Date])";
