行计数基于CONVERT输出

Question

这就是我目前所拥有的：

我的目标是搜索次数如下......

我的实际表有一个DatetimeSelected DataTime字段，我只需要计算日期。我使用＆＃39; 转换＆＃39;现在想按日期计算每个搜索次数 到目前为止，这是我的代码......

SELECT        

CONVERT(VARCHAR(10), DateTimeSelected, 103) AS [Book Date]
,Bathrooms
,Count (CONVERT(VARCHAR(10), DateTimeSelected, 103)) AS 'No of Searches'

FROM dbo.Stats_Bathrooms WITH (NOLOCK)

WHERE (DateTimeSelected BETWEEN GETDATE() - 7 AND GETDATE())

GROUP BY ID, DateTimeSelected, Bathrooms, SessionID

任何帮助非常非常感谢！

Answer 1

您应该只GROUP BY CONVERT(VARCHAR(10), DateTimeSelected, 103), Bathrooms：

SELECT
    CONVERT(VARCHAR(10), DateTimeSelected, 103) AS [Book Date]
    ,Bathrooms
    ,Count (CONVERT(VARCHAR(10), DateTimeSelected, 103)) AS 'No of Searches'
FROM dbo.Stats_Bathrooms WITH (NOLOCK)
WHERE (DateTimeSelected BETWEEN GETDATE() - 7 AND GETDATE())
GROUP BY CONVERT(VARCHAR(10), DateTimeSelected, 103), 
         Bathrooms;
