Converting Mssql 'For Xml Path' to Oracle
I Have a Statement to Fill a Table on My Mssql Database. It Joins Some Values Together Seperated by a Semicolon. Insert into Xxaarcdocswsb (Arcdocinr, Sworte)...
I have a Statement to fill a table on my MSSQL Database. It joins some values together seperated by a semicolon.
INSERT INTO XXAArcDocSWSB (ArcDocINr, SWorte)
SELECT A.ArcDocINr, B.SWorte FROM XXAArcDoc A
LEFT JOIN (
SELECT DISTINCT T2.ArcDocINr,
SUBSTRING(
(
SELECT ';' + T1.SWort AS [text()]
FROM (SELECT D.ArcDocINr, SW.SWort FROM XXAArcDoc D, XXAArcSW SW WHERE D.ArcDocINr = SW.ArcDocINr) T1
WHERE T1.ArcDocINr = T2.ArcDocINr
For XML PATH ('')
), 2, 255) [SWorte]
FROM (SELECT D.ArcDocINr, SW.SWort FROM XXAArcDoc D, XXAArcSW SW WHERE D.ArcDocINr = SW.ArcDocINr) T2
) B ON A.ArcDocINr = B.ArcDocINr
I don't have enough Knowledge to convert this to Oracle. It should give me the same Output as from MSSQL. Can someone help me?
EDIT:
Here is some sample data:
XXAArcDoc:
ArcDocINr | ...
----------|----------
1 |
2 |
3 |
. |
. |
. |
XXAArcSW:
ArcSWINr | ArcDocINr | SWort
---------|-----------|---------
6 | 1 | Müller
7 | 1 | 100
8 | 2 | 111111
9 | 2 | 13579
10 | 2 | 002
11 | 3 | TM-AH
And here is my desired Output:
ArcDocINr | SWorte
----------|---------
1 | Müller;100
2 | 111111;13579;002
3 | TM-AH

Use LISTAGG:
SELECT ArcDocINr,
LISTAGG(
SWort,
';'
) WITHIN GROUP ( ORDER BY ArcSWINr ) AS SWorte
FROM XXAArcSW
GROUP BY ArcDocINr;
Update:
If you are inserting into the XXAArcDoc table using values from the XXAArcSW table then something like:
INSERT INTO XXAArcDoc ( ArcDocINr, SWorte )
SELECT ArcDocINr,
LISTAGG( SWort, ';' ) WITHIN GROUP ( ORDER BY ArcSWINr )
FROM XXAArcSW
GROUP BY ArcDocINr
