you need use union between 2 tables, , add additional columns customized, set desired order generate required output

ex [in oracle syntax, idea same]

    select          case when oid = 0 to_char(p_tradeid) else portfolio end tradeid, portfolio, ticker, company,shares, action, comments         (         select             id oid, 1 soid,             tradeid p_tradeid,             to_char(id) portfolio, -- important change datatype of columns matching in union in order union statement work             ticker,             company,             to_char(shares) shares,             to_char(action) action,             comments                 (             --here select statement.... below demo             select 1 id, 1 tradeid, 'msft'  ticker, 'microsoft'  company, 100 shares, 'buy'  action, 'test' comments dual union             select 2 id, 1 tradeid, 'ibm'   ticker, 'ibm'        company, 200 shares, 'sell' action, 'test' comments dual union             select 3 id, 2 tradeid, 'yahoo' ticker, 'yahoo inc'  company, 50  shares, 'sell' action, 'test' comments dual union             select 4 id, 2 tradeid, 'goog'  ticker, 'google inc' company, 500 shares, 'buy'  action, 'test' comments dual         )          union --the trick union here          select             0 oid,0 soid, --and order columns here , in above query             id p_tradeid,             portfolio,             source ticker,             version company,             to_char(createdon) shares,             to_char(status) action,             '' comments                 (             --and again, make sure datatype of columns same!             select 1 id, 'test1' portfolio, 'rim' source, '1.0' version, '2016-01-20' createdon, 1 status  dual union             select 2 id, 'test2' portfolio, 'ios' source, '1.0' version, '2016-01-20' createdon, 1 status  dual         )     )     order          p_tradeid, soid, oid

this generate following:

1 | test1   | rim   |   1.0         | 2016-01-20 |  1       |  1 | 1       | msft  |   microsoft   | 100        |  buy     | test 2 | 2       | ibm   |   ibm         | 200        |  sell    | test 2 | test2   | ios   |   1.0         | 2016-01-20 |  1       |  3 | 3       | yahoo |   yahoo inc   | 50         |  sell    | test 4 | 4       | goog  |   google inc  | 500        |  buy     | test
