Hello,
I'm facing a problem about table view. My problem is the following:
I have
-
Table Car ( id_car, id_color_out, id_color_rims, id_color_bumper, model)
Table Color( id_color, name_color)
-
So, id_color_out, id_color_rims, id_color_bumper are foreign keys of table color.
In native sql the view was something like this:
-
select id_car, c1.name_color, c2.name_color, c3.name_color, model
from car inner join
color as c1 on c1.id_color = car.id_color_out inner join
color as c2 on c2.id_color = car.id_color_rims inner join
color as c3 on c3.id_color = car.id_color_bumper
-
I don't know how to do this in a VIEW. Can anyone help me?
Thanks in advance!

Hi Paulo Santos ,
Go to se11.
Select the 'View' Radio Button
enter View name(ZCar_color_view) click enter and (Select Database View)enter.
Click on create
Entert Car and Color in the table panel window
Give the condtions in the join conditions panel(as given in the inner join)
Give the field names that you want to see after the join
Save and activate.
Automatically data will be populated as joined.
Hope this helps you.

hello Rama Chary ,
first thank you for your fast response!
unfortunatly your solution doesn't work.
look at this example.
Car (1,1,2,3,"Ferrari")
Color(1,"Red")
Color(2,"Blue")
Color(3,"Black")
The view should return:
(id_car, c1.name_color, c2.name_color, c3.name_color, model)
1, Red, Blue, Black, Ferrari
I believe that your solution doesn't return any value because in my join conditions I have:
color.id_color = car.id_color_out
color.id_color = car.id_color_rims
color.id_color = car.id_color_bumper
and the result is
color.id_color =1
color.id_color =2
color.id_color =3
so this can't work because color.id_color can't be equal to 1 AND 2 AND 3...
In vision fields I inserted:
VISION_FIELD -
TABLE NAME -
FIELD NAME
ID CAR -
car -
id_car
COLOR OUT -
car -
id_color_out
COLOR RIMS -
car -
id_color_rims
COLOR BUMPER -
car -
id_color_bumper
MODEL -
car -
model
Is this correct?
