dynamic update -> comma prob

[Michael Zurke]

hi,

i got the following statement:
<update id="update" parameterClass="java.util.Map">
      UPDATE public.master
      SET
      <isPropertyAvailable property="name">
        name        = #name#,
      </isPropertyAvailable>
      <isPropertyAvailable property="othername">
        othername   = #othername#
      </isPropertyAvailable>
        WHERE id = #id#
    </update>

Now is there an easy way to get rid of the comma after #name# in case 
that the property "othername# is not available? or do i have to check
if "othername" is set before setting the name field. for this example it 
would be kind of ok but let's assume i do the same for lots of fields...err.

any ideas?

thanx,
mish
