efficient management of comma in dynamic statement

[Tite Etoundi]

Hi,
   
  Plz do anybody could help me how can I manage comma in statement as the 
follow:
   
   <update id="UpdateProduct" parameterClass="ProduitVOType" >
      UPDATE PRODUIT SET
        <dynamic>
            <isGreaterEqual property="IdCategory" compareValue="0">
              idCat = #IdCategory#
            </isGreaterEqual>
            
            <isNotNull property="CaractTechniques" prepend=",">
              caracteristiquesTech = #CaractTechniques#
            </isNotNull>
            
            <isNotEmpty property="DescriptionDetaillee" prepend=",">
                descDetaillee = #DescriptionDetaillee#
            </isNotEmpty>      
            
            <isNotEmpty property="ImageBasePath" prepend=",">
              imageBasePath = #ImageBasePath#
            </isNotEmpty>
              <isNotEmpty property="NomProduit" prepend=",">
              name = #NomProduit#
            </isNotEmpty>
              <isGreaterEqual property="QteEnStock" compareValue="0" 
prepend=",">
              qteEnStock = #QteEnStock#
            </isGreaterEqual>
        </dynamic>
      
      WHERE idProduit = #IdProduit#
    </update>
   
  For example when QteEnStock = -1 or IdCategory = -1, I get the following 
exception {"Line 1: Incorrect syntax near ','."}
   
  There could be a lot of cases as this one in this statement.
   
  Could somebody help me?
   
  Thanks.
