SQL Query help

Hi! my db schema is the following

Table CC
ut_item ,ut_ref

Table KWDS
ut , de

Table KWDS_PLUS
ut ,id

Table UT_2_CONSIDER
ut

Each CC.ut_item and CC.ut_ref
has a KWDS.ut
I am trying to combine each ut_item's KWDS.de with the ut_ref's KWDS.de

ut_item-> KWDS.de | ut_ref->de
how can i make a select statement for that?

I Hope i was clear enough
Thank you!
