Question
Let say I have 1 parent data and 3 child data like a chain:
Parent -> Child 1 -> Child 2 -> Child 3
using table wizard in the designer I can get any data except that has no Child 3 data in our case. To explain this, let say we have a database like this:
Cars that I own: Car Brands --> Car Models --> Modifications I have 2 data like these:
Ford --> Focus --> Spoiler, Body Kit, New Brake System Mercedes --> C180 --> \No data for modifications, since I dont have any\
Report builder show only the Ford Focus. It does not show mercedes since there is no modification on it. How can I make report builder 3 show all of them?
Or can you suggest any other reporting solution that does at least listing of my data with no visualisations or fancy effects. I need export to excel option only.
La solution
The problem is in my select statement:
SELECT
Kolonminhas.KolonminhaID
,Kolonminhas.KolonID AS [Kolonminhas KolonID]
,Kolonminhas.Aciklama
,Kolonminhas.En AS [Kolonminhas En]
,Kolonminhas.Boy AS [Kolonminhas Boy]
,Kats.KatID AS [Kats KatID]
,Kats.BlokID AS [Kats BlokID]
,Kats.Ad AS [Kats Ad]
,Kats.Kolonaltkot
,Kats.Kolonustkot
,Bloks.BlokID AS [Bloks BlokID]
,Bloks.ProjectID
,Bloks.Ad AS [Bloks Ad]
,Kolons.KolonID AS [Kolons KolonID]
,Kolons.KatID AS [Kolons KatID]
,Kolons.KolonAdi
,Kolons.En AS [Kolons En]
,Kolons.Boy AS [Kolons Boy]
,Kolons.Yukseklik
,Kolons.Altkot
,Kolons.UstKot
FROM
Kolons
INNER JOIN Kolonminhas
ON Kolons.KolonID = Kolonminhas.KolonID
INNER JOIN Kats
ON Kolons.KatID = Kats.KatID
INNER JOIN Bloks
ON Kats.BlokID = Bloks.BlokID
To solve this issue OUTER JOIN command should be used. However I am not able to create one. I would appreciate it if someone help me.
And this is the correct query:
SELECT
Kolonminhas.KolonminhaID
,Kolonminhas.KolonID AS [Kolonminhas KolonID]
,Kolonminhas.Aciklama
,Kolonminhas.En AS [Kolonminhas En]
,Kolonminhas.Boy AS [Kolonminhas Boy]
,Kats.KatID AS [Kats KatID]
,Kats.BlokID AS [Kats BlokID]
,Kats.Ad AS [Kats Ad]
,Kats.Kolonaltkot
,Kats.Kolonustkot
,Bloks.BlokID AS [Bloks BlokID]
,Bloks.ProjectID
,Bloks.Ad AS [Bloks Ad]
,Kolons.KolonID AS [Kolons KolonID]
,Kolons.KatID AS [Kolons KatID]
,Kolons.KolonAdi
,Kolons.En AS [Kolons En]
,Kolons.Boy AS [Kolons Boy]
,Kolons.Yukseklik
,Kolons.Altkot
,Kolons.UstKot
from Bloks
left join (Kats left join (Kolons left join Kolonminhas on Kolons.KolonID = Kolonminhas.KolonID) ON Kats.KatID = Kolons.KatID) ON Bloks.BlokID = Kats.BlokID
