如何在SQL Server中舍入十进制值

Question

I want to round the value from 1572.750000 to 1572.75

SELECT ROUND(1572.750000, 2)

I tried above format, but it was not working. Please any one help me out.

Answer 1

I think the simplest way is to convert to decimal :

select cast(1572.750000 as decimal(10, 2))

If you want a string output, you can use the str() function (documented here ).

The confusion occurs because round() changes the value , but it does not change the type . Hence, whatever application is using the value can format it as it wants. When the application knows that the value has only two decimal places (with decimal(10, 2) ) or the code converts directly to a string, then this is not an issue.
