''     6
''     10
GREEN     15
"     2
BLUE     10
"     5
How can i do this ? I am waiting for your early reply.

Answer 1

In Data Model, find the group that contains your data.
In that group:
1. create a formula column named for example ”CF_set_value_color”
2. create a placeholder column named for example ”CP_show_value_color” of VARCHAR2
Outside the group; create a stand alone placeholder named ”CP_last_value_color” of VARCHAR2
Now, create a PL/SQL procedure for your formula column ”CF_set_value_color:
”color” should be replaced with the name of the column that returns RED, GREEN or BLUE..
function CF_set_value_colorFormula return Number is
begin
-- First row
if :cp_last_value_color is null then
-- Set values for placeholders
:cp_last_value_color := :color;
:cp_show_value_color := :color;
else
-- Second row and beyond
if :cp_last_value_color = :color then
-- If last color is the same as the current, show "
:cp_show_value_color := '"';
else
-- If last color is NOT the same as this one, show new color
:cp_last_value_color := :color; -- Set for comparison of next row
:cp_show_value_color := :color;
end if;
end if;
return 1;
end;
For each row the query retrieves, the value of “CP_show_value_color” will be RED, ”, ”, GREEN, ”, BLUE, ”
Use that column for output instead of ”color” and it should work just fine.
