Dynamic Coloumn update

Hi,
I need a help , I have a requirement as follows:

Update Table1
set Field1 = :Field1-Value,
Field2 = :Field2-Value,
Field3 = :Field3-Value
Where Field4 = '1234'.

Here I need to update Field3 only if Field3-Value is > spaces. If it is spaces
I should not update this Field in the Sql. Please let me know if there is any way to do this.

What data types are Field3 and Value?

Anyway, you can use CASE expression.
