HOW TO LOAD A FORMULA IN A SPECIFIC FIELD VIA SCRIPT

[gabroteddy]

I extract the some value by this script...

SELECT r.numero as ID

,sr.id || '_' || rownum IDs

,nvl(EXTRACTVALUE(value(Modulo),'//child::*[@modelCodeScheme="prova" and @modelCodeValue="1"]/text()'),'campo vuoto') PROVA1_DATA

,nvl(EXTRACTVALUE(value(Modulo),'//child::*[@modelCodeScheme="prova" and @modelCodeValue="1.1"]/text()'),'campo vuoto') PROVA1_ORA

,nvl(EXTRACTVALUE(value(Modulo),'//child::*[@modelCodeScheme="prova" and @modelCodeValue="2"]/text()'),'campo vuoto') PROVA2_DATA

,nvl(EXTRACTVALUE(value(Modulo),'//child::*[@modelCodeScheme="prova" and @modelCodeValue="2.1"]/text()'),'campo vuoto') PROVA2_ORA

FROM TBREF c

join REFER r on c.REFER = r.NUMERO

join SR sr on sr.SI_ID = r.SI_ID

, TABLE(XMLSEQUENCE(EXTRACT(XMLType(REPLACE(sr.xmldata, 'xmlns="http://www.PROVA.it/2008/FMSchema"', '')),'//modulo'))) Modulo

WHERE sr.XMLDATA is not null;

And after with the formula

= interval(Timestamp#(  PROVA1_DATA &' '&

PROVA1_ORA,'YYYY-MM-DD hh:mm:ss') - Timestamp#(PROVA2_DATA &' '&

PROVA2_ORA,'YYYY-MM-DD hh:mm:ss'),'mm')  i've calculated the interval in

each row...

but i don't know how i can utilize this formula to create a specific field load directly in the script...the objective is to  use this field in other dashboard without applicate the formula.

Solutions?
