sql server - Birt filter data set -


i have sql code 

select id1, ' ' id2, balance1, 0 balance2    table 1   union   select ' ' id1, id2, 0 balance1, balance2    table 2

table 1 , table 2 have no relations, cannot use join.

in report template have created table binded data set columns sql code outputs.

i have put 2 detail rows in table this

head:         id                       balance     detail1:     [id1]                 [balance1]    detail2:     [id2]                            [balance2]

i need filter out data table2 in detail1 , filter out data table1 in detail2. how do this?

also table report results crossing data this: 

[id1]     [balance1]    [id2]               [balance2]   [id1]     [balance1]    [id2]               [balance2]

and need 1 detail reuslt on top , 1 on bottom : 

[id1]     [balance1]    [id1]     [balance1]      [id2]               [balance2]     [id2]               [balance2]

how should set report template?

i think need query this:

select * (     select id1, ' ' id2, balance1, 0 balance2, 1 ord        table 1       union       select ' ' id1, id2, 0 balance1, balance2, 2 ord     table 2  ) dt order      ord, id1, id2
