I've two Ms Access tables with the same structure.
This is a PostgreSQL list - you'd probably be better using a Microsoft-Access list.
[snip]
Here what we should observe is, 1st row in table 1 not present in table2. 2nd row in table1 is modified in table2. 3rd row in table 2 is not present in table1. So, after comparing table 1 and table2, the differences are captured as old and new. Old referes to table1 data and new referes to table2 data. The rows that are equal in both table 1 and table 2 should not be captured in table 3.
Is itpossible to do this in Ms Access? If so, how.
In general terms, with MS-Access, I'd build separate queries for each step. So you'd want a query for:
1. Reset table3
2. Insert to table3 rows in table1 and not in table2
3. Insert to table3 rows in table2 and not in table1
...etc...
