Filtering data that could have more than one category @dezso Is the first "EXISTS ( SELECT .." query mandatory? I tried this: SELECT document, term
FROM Annotation ann
WHERE category = 1
AND NOT EXISTS (
SELECT 1
FROM Annotation a
WHERE
a.document = ann.document
AND a.term = ann.term
AND category <> 1
). Is this correct the same? |
