SELECT DISTINCT a, b, c, now(), count(item_pk)
FROM product
LEFT JOIN item ON item.product_fk = product_pk
WHERE ...
GROUP BY a, b, c
I have another table 'navigation' which also has the columns a,b,c
If the combination of (a,b,c) exists in 'navigation', then exclude it
from above result. How can I achieve this?
