here it is
SELECT Table1.*
FROM Table1 LEFT JOIN table2 ON
(table1.[fielda] = table2.[fielda]
AND
table1.[fielda] = table2.[fielda]
and etc...
)
WHERE (((table2.[fielda]) Is Null));

try the below :

SELECT a.*
FROM Table1 a
where not exists ( select 1 from table2 b where b.fielda = a.fielda and b.fieldb=a.fieldb );

mrong: your query is already fine, the code of nav_kum_v should work exactly the same.
