以下是我的代码片段。请问，我在哪里加入你的 码？

$query="SELECT name, timestamp, number, comment FROM table WHERE
name = '$valid_user' and timestamp between '$start_date' and '$end_date'"; 
$params = array($_REQUEST['query']); 
$result = sqlsrv_query($conn, $query, $params);

echo "<p><table id='t01' border='1'>

<th style='width: 10px'>Date </th> 
<th style='width: 5px'>Number</th>
<th style='width: 100px'>Comment</th> 

</tr>";

while($row = sqlsrv_fetch_array($result, SQLSRV_FETCH_ASSOC))  {    
    echo "<tr>";
    echo '<td><a href=#.php?id='.strip_tags($row['id']).'>'  . date( 'd M Y', strtotime(strip_tags($row['timestamp']))). "</td>";

    echo "<td>" . strip_tags($row['number']). "</td>";
    echo "<td>" . strip_tags($row['comment']). "</td>";
    echo '<td><a href="#.php?id=' . strip_tags($row['id']). '">Edit/Delete</a></td>';
    echo "</tr>";
    echo "</tr>";         }

非常感谢帮助。

提前致谢。

以下是您可以按周分组的模板：

DECLARE 
  @Year int = 2015,
  @Month int = 7

DECLARE @StartDate DATE = dateadd(mm, (@Year - 1900) * 12 + @Month - 1, 0)
DECLARE @EndDate DATE = dateadd(mm, (@Year - 1900) * 12 + @Month, -1)

;WITH tally AS (
    SELECT (row_number() OVER(ORDER BY (SELECT 0))) - 1 AS N
    FROM master.dbo.syscolumns sc1)
SELECT 
    --d,
    wknr
FROM 
    tally
    CROSS APPLY(
        SELECT 
            d = DATEADD(DAY, N, @StartDate),
            wknr = DATEPART(wk, DATEADD(DAY, N, @StartDate))) dates
WHERE d < @EndDate
GROUP BY wknr
ORDER BY wknr

修改

我建议您根据需要定制提供的查询模板。我在你的PHP代码中看到你需要字段name, timestamp, number, comment，所以查询应该返回它们。

下一步是用新的查询替换旧查询。相应地传递日期参数。

我想你可以使用类似的东西：

;WITH tally AS (
    SELECT (row_number() OVER(ORDER BY (SELECT 0))) - 1 AS N
    FROM master.dbo.syscolumns sc1)
SELECT 
    wknr,
    number = SUM(t.number)
FROM 
    tally
    CROSS APPLY(
        SELECT 
            d = DATEADD(DAY, N, @StartDate),
            wknr = DATEPART(wk, DATEADD(DAY, N, @StartDate))) dates
    JOIN table t
        ON t.timestamp = d
WHERE d < @EndDate
GROUP BY wknr
ORDER BY wknr
