Oracle find record by multiple matching criteria

Question

I'm trying to find records by multiple matching values in two columns.

Just to give you an example on what I'm trying to do: I have a form which is saved in the database and contains checkboxes about a sickness, which can or cannot be present when a patient is admissioned in the hospital.

These are like:

Acquistion Time: Admission [ ]  Follow-Up [ ]  Transfer [ ]  Discharge [ ]
Illness present? Yes [ ]  No [ ]

So patients can have multiple of those surveys.

Now what I'm trying to do: I have to find patients where the illness WAS NOT present when they entered the hospital ( combination of Admission and No ) BUT evolved during their stay ( combination of Follow-Up and Yes )

My idea was to go with two EXISTS statements, but it didn't work out (+ the runtime is really long):

EDIT :

The dataset I have right now (I didn't add the whole query at first) looks like this (limited to one case to make it readable):

CaseNumber	CaseID	Admission Date	Acquisition Date	Flag	Checkbox
123456789	123	09.11.2020	13.11.2020 16:13	1	cbxAdmission
123456789	123	09.11.2020	13.11.2020 16:13	0	cbxFollowUp
123456789	123	09.11.2020	13.11.2020 16:13	0	cbxIllnessPresent
123456789	123	09.11.2020	13.12.2020 10:23	0	cbxAdmission
123456789	123	09.11.2020	13.12.2020 10:23	1	cbxFollowUp
123456789	123	09.11.2020	13.12.2020 10:23	1	cbxIllnessPresent
123456789	123	09.11.2020	20.11.2020 07:38	0	cbxAdmission
123456789	123	09.11.2020	20.11.2020 07:38	1	cbxFollowUp
123456789	123	09.11.2020	20.11.2020 07:38	0	cbxIllnessPresent

This is the according query:

SELECT DISTINCT
    f.FALLNR AS "Fall",
    f.FALLID,
    TO_CHAR(f.AUFNDAT, 'DD.MM.YYYY') AS "Aufnahmedatum",
    --cf.TEXT AS "Text",
    CONCAT(CONCAT(TO_CHAR(cp.MEDDATE, 'DD.MM.YYYY'), ' '), TO_CHAR(cp.MEDTIME, 'HH24:MI')) AS "Befundzeitpunkt",
    --cp.PRIMITIVUMNUMMER,
    --ck.NUMMER,
    cf2.FLAG,
    --cf2.WERT,
    cf3.CODE
FROM
    OS_CW.CW_PRIMITIVUM cp 
    INNER JOIN FALL f ON f.FALLID = cp.FALL
    INNER JOIN OS_CW.CW_KLASSE ck ON ck.NUMMER = cp.KLASSE
    LEFT JOIN OS_CW.CW_FELDTEXT cf ON cf.PRIMITIVUMNUMMER = cp.PRIMITIVUMNUMMER
    LEFT JOIN OS_CW.CW_FELDDATEN cf2 ON cf2.PRIMITIVUMNUMMER = cp.PRIMITIVUMNUMMER
    LEFT JOIN OS_CW.CW_FELDCODE cf3 ON cf3.NUMMER = cf2.FELDDEFINITION 
WHERE
    ck.MAPPENNUMMER = 16
    AND f.FALLNR = 123456789
    AND f.MEDICALCASESTATE IN (65366, 65369)
    AND f.CASEMARK IN (38140, 38142)
    AND EXTRACT(YEAR FROM f.ENTLDAT) = 2021
    AND cp.STORNIERT = 0
    AND (cf3.CODE = 'cbxAdmission' OR cf3.CODE = 'cbxFollowUp' OR cf3.CODE = 'cbxIllnessPresent')
GROUP BY f.FALLNR, f.FALLID, CONCAT(CONCAT(TO_CHAR(cp.MEDDATE, 'DD.MM.YYYY'), ' '), TO_CHAR(cp.MEDTIME, 'HH24:MI')), TO_CHAR(f.AUFNDAT, 'DD.MM.YYYY'), cf2.FLAG, cf3.CODE
ORDER BY CONCAT(CONCAT(TO_CHAR(cp.MEDDATE, 'DD.MM.YYYY'), ' '), TO_CHAR(cp.MEDTIME, 'HH24:MI')), cf3.CODE DESC

Now I need a query that returns the CaseNumber and the acquistion date if the criteria I already described matches - which should be the case here because it wasn't present on admission / first acquisition (13.11.2021) but it then it evolved and was present on the next acquistion (13.12.2021), which is a follow-up.

I thought of analytical functions but couldn't find one which fits my needs (I'm not the most experienced person in Oracle DBMS).

Any ideas if (and if yes - how) this could be turned into a query?

Thanks for any helpful anwers!

Answer 1

I think you can combine those with or in last condition as below:

AND EXISTS (
    SELECT *
    FROM OS_CW.CW_PRIMITIVUM cp2 
    JOIN OS_CW.CW_FELDTEXT cf4 ON cf4.PRIMITIVUMNUMMER = cp2.PRIMITIVUMNUMMER
    JOIN OS_CW.CW_FELDDATEN cf5 ON cf5.PRIMITIVUMNUMMER = cp2.PRIMITIVUMNUMMER
    JOIN OS_CW.CW_FELDCODE cf6 ON cf6.NUMMER = cf5.FELDDEFINITION 
    WHERE cp2.FALL = f.FALLID
    AND (((cf6.CODE = 'cbxAdmission' AND cf5.FLAG = 1) AND (cf6.CODE = 'cbxIllnessPresent' AND cf5.FLAG = 0))
    or ((cf6.CODE = 'cbxFollowUp' AND cf5.FLAG = 1) AND (cf6.CODE = 'cbxIllnessPresent' AND cf5.FLAG = 1)))

Answer 2

Okay, after some trial and error and logical thinking about it I managed to put a working query together, I just used INNER JOIN to always combine the matching criteria between the different tables.

The final result looks like this (don't mind the German descriptions etc.)

 SELECT

"Vorname",
"Name",
"Geburtsdatum",
"Aufnahmedatum",
