Denne forespørgsel kan være en god start som grundlag for yderligere eksperimenter:
With src As (
SELECT lmnt.element_name
, lmnt.element_entry_id
, nval.input_value_id
, nval.screen_entry_value
-- , eval.name
, row_number() over (partition by lmnt.element_name, lmnt.element_entry_id
order by lmnt.element_name ) rn
FROM XX_SAMPLE_ELEMENTS lmnt
, XX_ENTRY_VALUES nval
, XX_ELEMENT_VALUES eval
where lmnt.element_entry_id = nval.element_entry_id
and eval.INPUT_VALUE_ID = nval.INPUT_VALUE_ID
order by lmnt.element_name
)
SELECT * FROM src
PIVOT (
max( input_value_id ) As input_value,
min( screen_entry_value ) as screen_entry_value
FOR (rn)
IN (1,2,3,4,5)
)
