Hi,

i have Table1:

Field1;Field2;Diff1;Diff2 [Headers]

1 1 Dif11 Dif11
1 2 Dif22 Dif22

and Table2:

Field1;Field2;Diff1;Diff2 [Headers]

1 1 Dif11 Dif11
1 3 Dif22 Dif22

What i want to get is:

Field1;Field2;Diff1;Diff2 [Headers]

1 1 Dif11 Dif11
1 2 Dif22 Dif22
1 3 Dif22 Dif22

So i want to append queries (like UNION in SQL) but without having duplicates based on primary keys: Field1 and Field2 as composite keys. 

Please help,
Jacek

Hi Jacek,

Can't you just append and then remove duplicates?

You can remove duplicates based on one or more columns. Simply choose the columns before clicking Remove Duplicates.
