union all 
select column1b,column2,coulmn3,column4,'' as columna,columnb from table2

Answer 2

You don't want a FULL OUTER JOIN , you want a UNION .

SELECT Column1A as Column1, Column2, Column3, Column4, ColumnA, NULL AS ColumnB
FROM Table1
UNION ALL
SELECT Column1B, Column2, Column3, Column4, NULL, ColumnB
FROM Table2;
