    Fetching records from multiple tables

    hi
    i am having a situation where i need to
    use three tables. Fetch records from first
    on the basis of those search the second table
    if it is found there then tag it true else
    search in the third and tag it if it is not there
    then tag it false.
    right now i am doing it it in linear fashion
    ie retirieving value from first then searching it
    in second and then in third, it is working fine
    for small data set but when huge records are there
    then disaster....
    i have tried join also but no success..
    here is what i need..
    Table1
    Id name
    1 a
    2 b
    3 c
    4 d
    Table2
    Id name
    1 a
    2 b

    Table3
    Id name status
    3 c ss

    and i need the output of the query as
    id
    1
    2
    3
    4

    Status
    true
    true
    ss
    false

    Any suggestions... thanks in advance
Working...
