Question

What is the correct syntax for Minus Query in MS ACCESS

I want to compare entire result set of 2 queries not just only key
column comparisons

For Eg:

hello table data: id,name,address

hello1 table data:new_id,new_name,new_address

I want to find out who are all the customers with changed data in any column.

I had given following query .it failed

select h.* from hello h
minus
select h1.* from hello1 h1

Please let me know correct query

One possibility is NOT IN. There is no such thing as a minus query in MS Access.

select h.* from hello h
WHERE uniqueid NOT IN
(select uniqueid from hello1 h1)

For a purely sql solution, you need, say:

SELECT t.* FROM Table t
LEFT JOIN NewTable n
ON t.ID = n.ID
WHERE t.Field1 & "" <> n.Field1 & ""
   OR t.Field2 & "" <> n.Field2 & ""

However, it is easier using VBA.
