GetYear help for a complete noob

Question

Hey.
I'm creating a sql data set for my data model that goes like this:
select     "Credit Memo"."Cm Fecha Creacion" as "Cm Fecha Creacion",
     "Medidas CM (Nivel RF)"."Cm Monto Total" as "Cm Monto Total",
     "Medidas RF (Nivel RF)"."Rf Monto Total" as "Rf Monto Total"
from     "SAG"."Medidas RF (Nivel RF)" "Medidas RF (Nivel RF)",
     "SAG"."Medidas CM (Nivel RF)" "Medidas CM (Nivel RF)",     
     "SAG"."Credit Memo" "Credit Memo"
where YEAR("Credit Memo"."Cm Fecha Creacion") = YEAR(:p_year)
but i get into 2 errors when doing this.
1)When saving the data set The YEAR(:p_year) errors out
2)If I put where YEAR("Credit Memo"."Cm Fecha Creacion") = :p_year (no year function on the right side)
it saves but when running the xml data samle I get "parsing error"
I've went thought this forum. And i got to post recommending function like <?xdoxslt:get_year(‘2000-04-08’, $_XDOLOCALE)?>.
I have no clue where I can put them, its clear that SQL editor is not the place, right?.
Is there any XML editor for my data sets. Is the "code" view intended for this? How could I use it in that case?
Thanks!

Hi LD.
Thanks for the reply.  My MacBook won't even recognise the Time Capsule, I've messed about with the netowrk settings too much I think. 
I'm really really stuck.
