सबसे पहले tour_id
प्राप्त करें s जो शर्तों से मेल खाते हैं:
SELECT Tour_ID
FROM myTable
WHERE organisation LIKE 'Ikea'
GROUP BY Tour_ID
HAVING LEAST(COALESCE(MIN(A), '2019-01-01'), COALESCE(MIN(B), '2019-01-01'), COALESCE(MIN(C), '2019-01-01'), COALESCE(MIN(D), '2019-01-01')) >= '2018-05-01' AND
LEAST(COALESCE(MIN(A), '2019-01-01'), COALESCE(MIN(B), '2019-01-01'), COALESCE(MIN(C), '2019-01-01'), COALESCE(MIN(D), '2019-01-01')) < '2018-06-01';
फिर मूल पंक्तियों को प्राप्त करने के लिए इसे एक प्रश्न में डालें। ये रहा एक तरीका:
select t.*
from mytable t join
(SELECT organisation, Tour_ID
FROM myTable
WHERE organisation LIKE 'Ikea'
GROUP BY organisation, Tour_ID
HAVING LEAST(COALESCE(MIN(A), '2019-01-01'), COALESCE(MIN(B), '2019-01-01'), COALESCE(MIN(C), '2019-01-01'), COALESCE(MIN(D), '2019-01-01')) >= '2018-05-01' AND
LEAST(COALESCE(MIN(A), '2019-01-01'), COALESCE(MIN(B), '2019-01-01'), COALESCE(MIN(C), '2019-01-01'), COALESCE(MIN(D), '2019-01-01')) < '2018-06-01'
) tt
ON tt.tour_id = t.tour_id AND
tt.organisation = t.organisation;
