SQL: views and joins

Hello,

    Could someone spare a minute or two to help me out?

If I have two tables like this (ID and DATA are strings)

TABLE A
    ID_A
    DATA_A TABLE B
    ID_B
    DATA_B with the data

TABLE A
    ID_A DATA_A

'123' 'a-data'

and

TABLE B
    ID_B DATA_B

'123' 'b-data'
'124' 'b-data2'

how should I create a view that would collect this data like this:

VIEW V

    ID        DATA_A    DATA_B


    '123'    'a-data'        'b-data'

    '123'    null               'b-data2'
