当以XML输出时，SQL“浮动"数据类型导致不希望的浮动结果

问题描述

您可以简单地尝试:table1:具有类型为"float"的column1代替

You can try simply:table1: has a column1 of type 'float' instead of

SELECT column1 from Table1;给出表中所示的值.

SELECT column1 from Table1; gives values as seen in table.

说这将返回15.1

但是，如果您尝试

Select column1 from Table1 
FOR XML PATH('Table1'), Root('SomeRoot'), TYPE  

返回:1.510000000000000e + 001

returns: 1.510000000000000e+001

有人看到过这个，如何解决?在此先感谢:)

Has anyone seen this, and how was this fixed?thanks in advance :)

推荐答案

这是使用浮点数时得到的.您可以尝试以下操作:

This is what you get when you work with floating point numbers. You can try this though:

SELECT CONVERT(varchar(100), CAST(column1 AS decimal(38,2)))

您只需要调整小数位数的精度即可满足您的需求.

you will just need to adjust the precision on the decimal to fit your needs.
