选择id(在本例中为dupersid),其中第二列(在本例中为icd9codx)的值仅在(296311)和250中。
| dupersid | icd9codx

46166101 -9
46166101 250
46166101 272

预期结果

46166102 250

我试过了
SELECT dupersid, icd9codx FROM public.sample_test
WHERE icd9codx = 250 AND dupersid IN (select distinct dupersid from public.sample_test where icd9codx IN (296, 311));
但它也提供了像46166101这样的记录
最佳答案
你可以通过将2的幂相加的技巧来实现这一点:
SELECT *
FROM public.sample_test
WHERE dupersid IN(SELECT dupersid FROM public.sample_test
GROUP BY dupersid
HAVING SUM(CASE icd9codx WHEN 250 THEN 1
WHEN 296 THEN 2
WHEN 311 THEN 4
ELSE 8 END) IN (3, 5) AND
SUM(CASE WHEN icd9codx = 250 THEN 1
ELSE 0 END) = 1)
