Selection of database fields

Question

I have got two fields in a database.Those two fields are interrelated like the col2 has a priority over col1.whenever col2 is there it is selected as the field(here it is a date).Below is the sql query i have written for that
select DECODE (cd.col1,'', TO_CHAR(cd.col2,'DD/MM/YYYY'),TO_CHAR(cd.col1,'DD/MM/YYYY'))  date from table1wat i want to do is i want to have display that field in the jsp in two diff colors.like if the date field is col2 it will have diff TD class if it is col1 it will have diff TD color.
I am not sure how 2 go about that.Plz help me.......is there some way to do that in the sql query itself.

Answer 1

select DECODE (cd.col1,'', TO_CHAR(cd.col2,'DD/MM/YYYY'),TO_CHAR(cd.col1,'DD/MM/YYYY')) date from table1I am trying to put it like this :-
select
case cd.col1 when ''
     TO_CHAR(cd.col2,'DD/MM/YYYY') AS COLUMN2_date
else
     TO_CHAR(TO_CHAR(cd.col1,'DD/MM/YYYY')) AS COLUMN1_date
end
from table1
You can get the column names through java code - something
like ResultSetMetaData - I am sorry i don't actually remember that right now.
But check APIs.
if (COLUMN2_date is null ) show as red else blue
if (COLUMN1_date is null ) show as red else blue
Hope this way it helps.
