SQL Recursion 2.

Izstopni podatki so pa taki:

Kako bi naredil, da mi [RecID2-Ident] izpiše samo 1 vrstico. Torej če je večkrat "Key" da bo samo prva vrstica.

predvidevam, da ti prvi del poizvedbe vrne več zapisov. Je rešitev, da v prvem delu union all uporabiš distinct?

SELECT distinct
	[Kosovnica].[KoStZapisa] AS [KoStZapisa],
	[Kosovnica].[KoNadSifMp] AS [Parent],
	CAST('' AS VARCHAR) AS [RecID1-Parent],
	[Kosovnica].[KoSifStat] AS [KoSifStat],
	[Kosovnica].[KoPodSifMp] AS [Ident],
	CAST('Key' AS VARCHAR) AS [RecID2-Ident],
	[Kosovnica].[KoKolMateriala] AS [Kos.],
	[Kosovnica].[KoVarianta] AS [VariantaParent],
	[Kosovnica].[KoVariantaPod] AS [VariantaChild]
FROM 	[Kosovnica]
	FULL JOIN [MaticniPodatki] ON [Kosovnica].[KoPodSifMp] = [MaticniPodatki].[MpSifra]
WHERE	([Kosovnica].[KoPodSifMp] = PARSE('17893' AS INT USING 'Sl-SI'))
AND	([Kosovnica].[KoVarianta] LIKE CAST('%*%' AS VARCHAR(3)))

druga manj elegantna varianta, ki morda niti ni pravilna, da na koncu nad izhodom narediš poizvedbo in tam uporabiš distinct (tega bi se izogibal)

prozac :: 30. mar 2020, 20:59

lahko morda namesto rekurzije uporabiš connect by prior

select koVarianta as "RecID1-Parent", koVariantaPod as "RecID2-Ident"
from kosovnica
START WITH koVarianta IS NULL
CONNECT BY PRIOR koVarianta = koVariantaPod

sedaj nimam dostopa do baze, da bi sprobal če napisano res dela

Torej imam [RecursionSource] samo za drevesno strukturo in pa [FilteredSource] za vse idente.
Filteredsource in recursionsource nato inner joinam, tako da dobim imena za posamične idente.

Aja imam pa tsql.

korenje3 :: 30. mar 2020, 23:07

Opcija je da namesto

WHERE	([Kosovnica].[KoPodSifMp] = PARSE('17893' AS INT USING 'Sl-SI'))

uporabim

WHERE	([Kosovnica].[KoNadSifMp] = PARSE('17893' AS INT USING 'Sl-SI'))

vendar bo potem iskani ident v celoti izvzet iz queryja.

korenje: en nasvet. nauč se vejce med stolpci pisat v novi vrstici na začetku. sigurno bolj pregledno kot na koncu.

korenje3 :: 30. mar 2020, 23:19

torej vejica samostojno v novi vrstici?
vejice dajam spredaj sicer samo kadar testiram. sql stavek je pa avtomatsko generiran.

SELECT

, [Kosovnica].[KoNadSifMp] AS [Parent]
, XYZ

Mah ne, sam men se zdi bolj pregledno tako. In manj možnosti za napake je, da kaj pozabiš, če se vejica tlači na koncu :P Nisem profi samo meni je bolje tako in nisem edini. Če pozabiš kje vejco maš samo eno stolpec na koncu manj v rezultatih

Jap. Excel vba program za iskanje in izpis direktno v excel.

Načeloma sem hotel neko hitro skriptico narest v parih dneh, pa se je potem razvleklo... in na koncu 100x več dela.
Dejansko je program tako nasičen, da sem moral nova okna delat ker sem prišel do same omejitve vba. Pri 200 vtičnikih/okno začne program crkovat.

V glavnem sedaj iščem rešitev, kako bi prikazal še iskani ident v enem rowu, ki bi mu ročno nastavil količino na 1.

Problem je pa ta:
Če iščem po ident v KoPodSifMp namesto KoNadSifMp bo prikazal vse nadrejene, ki vsebujejo iskani ident, tako da se ta lahko večkrat ponovi, količina je pa lahko kar nekaj.

Celoten sql stavek je pa tak:

Opcija je seveda še en filteredsource, ki se ga joina ali naredi union, vendar bi bilo to programsko preveč balasta.
