and contains the sql code

Select a, b, ........From TableA

objectB is named sqlqueryB

and contains the sql code

Select a, m, n...... From sqlqueryA

objectC is named sqlqueryC

and contains the sql code

Select x, y, z ..... from sqlqueryB

each query is saved as a different object in my ms-access database , how can i create one object containing all queries

Answer 1

You can UNION:

Select a, b,"" as c ........From TableA
UNION ALL
Select a, m as b, n as c...... From sqlqueryA
UNION ALL
Select x As a, y as b, z as c ..... from sqlqueryB

Note that sqlqueryA and sqlqueryB could be included as subqueries.

You can JOIN, as long as you have a field with common data:

SELECT t.a, t.b,s.m, s.n...... 
FROM TableA t 
INNER JOIN sqlqueryA s
ON t.a=s.a
