I have a Table1 with a field T1_ID, and a Table2 with a field Link_T1_ID. 

All Table1 records have T1_ID values greater than 0. In Table2 several
records may have [ Table2] Link_T1_ID :=0.

I query Table1 with Table2 where [ Table2] Link_T1_ID :=0: QUERY([Table1];[
Table1] T1_ID =[ Table2] Link_T1_ID)

And I get 0 records, as expected.

I then query Table2 with Table1 where [ Table2] Link_T1_ID equals 0:
QUERY([Table2]; [ Table2] Link_T1_ID =[ Table1] T1_ID) 

And I get all the Table2 records where [ Table2] Link_T1_ID :=0 ( in other
word more records than 0 records).

Is this as expected when there is no Table1 records where [ Table1] T1_ID:=0
?
