If all your columns are the same in each sub query, then you can put a UNION ALL
between them and they will all append to the same query. The columns all have to be the same names and in the same order for this to work. If they are close but not exact, you can do things like add empty columns to one query so it will match another query. For example, if the first query has Name, Rank and Serial for the results, but the second query only has Name and Serial, you can write it like this:
SELECT Name, Rank, Serial FROM Table_A UNION ALL SELECT Name, '' AS Rank, Serial FROM Table_B
