我有一个名为的列TotalArea,其格式为numeric (12,2).

我想让它用千位分隔符显示数字,所以当我

select TotalArea from table

给我看一个像这样的格式1,234.00.

我怎么能这样做？谢谢!

我是SQL Server的新手,我有一个问题.

我有这个观点,其中公式中的一些列被允许为null.

我怎么能将这些空值转换为0,因为如果它们为null,则公式的结果也将为null.

谢谢!

请有人帮我解决这个问题:我有这个选择:

SELECT Cast(( Isnull(price, 0) + Isnull(notarycosts, 0)
              + Isnull(landtax, 0) + Isnull(othertaxes, 0)
              + Isnull(agentfee, 0) + Isnull(cadastralfee, 0)
              + Isnull(tabulationfee, 0)
              + Isnull(certsarcini, 0) ) / ( totalareasqm / 10000 * fixhist ) AS
                   DECIMAL(12, 4)) AS EurPerHa

有时我得到除零错误和我的应用程序它被阻止,直到我删除数据库的最后一行.我能以某种方式解决这个问题吗？

谢谢!
