of course, you need to have the same datatype between your null value and the value that you replace with.

For exemple :

coalesce ( field1,'') -> field1 must have a char or varchar datatype

you can't do colaesce( field2,'') if filed2 is a number

=> in this case, replace with

     case when field2 is null
          then ''
          else cast(field2 as varchar(n))
          end.
