Bug ID: 118492
Summary: (Correct) SQL-Query (wrongly) returns 0 (null) Values
in specific Column. DBMS: PostgreSQL
Product: LibreOffice
Version: 6.0.3.2 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Base
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: randmu...@gmail.com
Description:
Context: I'm working on setting up an anamnesis database for a medical
institution. My test-database needs to display certain disorders/diseases in
one table and associated risk situations in another.
Relevant Tables (if needed I can provide a graph of the database-design):
- hämo_erkrankung: id(int), lokalisation(int), person(int), zeitpunkt(date)
[eng: time of occurence]
FK: person -> person.id
lokalisation -> lokalisation.id
(one individual disease/disorder per row)
- situation: id(int), situation(varchar)
(one (risk-)situation per row)
- situation_p: id(int), hämo(int), situation(int)
FK: hämo -> hämo_erkrankung.id
situation -> situation.id
(n risk situations for one disease / disorder referenced by "hämo")
Problem: I wanted to create a Query displaying the actual situation associated
with a disease/disorder rather than the foreign key, using this SQL-Command:
SELECT "SP"."id", "SP"."hämo", "S"."situation"
FROM "situation_p" "SP", "situation" "S"
WHERE "SP"."situation" = "S"."id"
The desired result table is returned in Postgres (using the Terminal). However,
in Base the "S"."situation" column returns '0' in every row instead of the
referenced Varchar-Value from the situation table.
Since the Query works for the DBMS I cannot see that there is anything I can do
to make it work in Base. Therefore this might be a Base issue. Please let me
know if you think there is anything I did wrong.
Steps to Reproduce:
1. Use PostgreSQL as the DBMS
2. Create the tables and relationships (s. Description-section), add Data
3. Create the Query and run it (s. Description-section)
Actual Results:
Result-table using Base (see Description-section for Query)
[id, hämo, situation]
(1, 1, 0)
(2, 1, 0)
(3, 2, 0)
(4, 3, 0)
(.......)
Expected Results:
Result-table directly using PostgreSQL
[id, hämo, situation]
(1, 1, Körperliche Anstrengung)
(2, 1, Tamoxifen plus)
(3, 2, spontan)
(4, 3, Operation)
(.............)
Reproducible: Always
User Profile Reset: No
