Question

我正在忙于修改一个脚本，该脚本将临时表中的数据输出到发送给用户的脚本。它正在监视我们的SQL使用情况统计信息并用于报告等。我在下面的电子邮件代码之前输出了临时表，它正确地将我的十进制列保持为“12,12345”或DECIMAL(18, 5)。

然而，发送电子邮件的最后一节（附在下面）继续删除我的小数点，而是输出为“12,000”。有没有人可能会得到一些帮助，我在剧本中尝试了各种演员，用“。”代替“，”。反之亦然。

SET @xml = CAST((SELECT  
                     LEFT(UPPER([Server]), 20) AS 'td', '',
                     LEFT([Database], 30) AS 'td', '',
                     LEFT(Device, 30) AS 'td', '',
                     LEFT([GB_Growth], 20) AS 'td', '',
                     REPLACE(CAST([GB_Current] AS DECIMAL(18, 5)), '.', ',') AS 'td', '',
                     REPLACE(CAST([GB_Previous] AS DECIMAL(18, 5)), '.', ',')        AS 'td', '',
                     ISNULL(CONVERT(CHAR(20),[Current_Date], 20), '--------------') AS 'td', '',
                     ISNULL(CONVERT(CHAR(20),[Previous_Date], 20), '--------------') AS 'td', ''
                 FROM    
                     [tempdb].[dbo].[DB_Dev_Sizediff] 
                 ORDER BY  
                     [Server], [Database]
                 FOR XML PATH('tr'), ELEMENTS) AS NVARCHAR(MAX))

我已经离开了我在上面脚本中的尝试（这不起作用），但我希望这适用于以下列：

GB_Growth, GB_Current and GB_Previous

脚本中的原始功能正在执行以下操作，但是我一直在尝试各种不同的事情，因此上面的原因有所不同：

ISNULL(CONVERT(CHAR(23), [GB_Current]), '-----') AS 'td', ''

此外，导致这一点的所有内容都在DECIMAL中，我已经确认了这一点，直到这一步。

Answer 1

我不确定后台发生了什么，但我决定修改脚本以永远不使用临时表并直接保存到物理表中。一旦这样做，我在最终的XML构建语句中修改了from子句，并且查询工作没有将任何逻辑应用于实际列。

感谢您的帮助和建议，我想我只需要停下来看一下就可以放松心情了。
