Populating a column with rows from another table in SQL Server 2008
I'm trying to populate under a column in a table with the rows sequentially from another table one by one. Which means each data in a particular row must be added back to back into that column in the other table and then the next row should be added like this etc.
I tried every single way, searched everywhere but apparently one one has ever needed to do something like this before.
First, I tried to convert these rows into columns with pivot and then tried to import but failed again. Is there any proper way to do this?
All I know is that this won't be done with a simple
insert into tablename (columnname)
select *....
way I guess?
This is the example of the data table that I need to take values from. Each cell in each row must be taken back to back;
Defter No Mezarlık Sayfa No Satır No
--------------------------------------------
20-8 ÇAMLICA 1 1
20-8 ÇAMLICA 1 2
and then get inserted under "Value" column in this table;
TipId EvrakId IndexId Value KayitTarihi
--------------------------------------------
1 23 66 JohnMc NULL
2 45 32 NewYork NULL
Each column is nvarchar, so is Value column. So I want this table to be like this;
TipId EvrakId IndexId Value KayitTarihi
--------------------------------------------
1 23 66 JohnMc NULL
2 45 32 NewYork NULL
.. .. .. 20-8 ..
.. .. .. ÇAMLICA ..
.. .. .. 1 ..
.. .. .. 1 ..
.. .. .. 20-8 ..
.. .. .. ÇAMLICA ..
.. .. .. 1 ..
.. .. .. 2 ..
This is my first table's full structure, the one that includes data in it.
CREATE TABLE [dbo].[EvrakUstBilgileri](
[Evrak Id] [float] NULL,
[Defter No] [nvarchar](255) NULL,
[Mezarlık] [nvarchar](255) NULL,
[Sayfa No] [nvarchar](255) NULL,
[Satır No] [nvarchar](255) NULL,
[Ada No] [nvarchar](255) NULL,
[Mezar No] [nvarchar](255) NULL,
[Adı Soyadı] [nvarchar](255) NULL,
[Doğduğu Gün] [nvarchar](255) NULL,
[Yaş] [nvarchar](255) NULL,
[Cinsiyet] [nvarchar](255) NULL,
[Öldüğü Gün] [nvarchar](255) NULL,
[Gömüldüğü Gün] [nvarchar](255) NULL,
[Defin Ruhsatiye No] [nvarchar](255) NULL,
[Defin Ruhsatiye Tarihi] [nvarchar](255) NULL,
[Defin Ruhsatiye Verildiği Yer] [nvarchar](255) NULL,
[Eşleştirme Yapıldı] [nvarchar](255) NULL,
[Evrak Barkodu] [nvarchar](255) NULL,
[Okunamadı] [nvarchar](255) NULL,
[Not] [nvarchar](255) NULL,
[Belge Tarihi] [nvarchar](255) NULL
) ON [PRIMARY]
This is the second table that I need to populate.
CREATE TABLE [dbo].[TblEvrakTipValue](
[TipId] [int] NOT NULL,
[EvrakId] [int] NOT NULL,
[IndexId] [int] NOT NULL,
[Value] [nvarchar](250) NULL,
[KayitTarihi] [datetime] NULL
) ON [PRIMARY]
Both of these tables have the same "EvrakId" column which should act as if its a primary key.
This is the table 1 that already has data in it;
EvrakId DefterNo Mezarlik SayfaNo SatirNo
5018352 20-8 ÇAMLICA 1 1
5018353 20-8 ÇAMLICA 1 2
5018354 20-8 ÇAMLICA 1 3
5018355 20-8 ÇAMLICA 1 4
5018356 20-8 ÇAMLICA 1 5
IndexId structure should be like this;
TipID EvrakID IndexID Value KayitTarihi
1 23 66 JohnMc NULL
NULL 23 67 20-8 NULL
NULL 23 68 ÇAMLICA NULL
NULL 23 69 1 NULL
NULL 23 70 1 NULL
2 45 66 NewYork NULL
NULL 45 67 20-8 NULL
NULL 45 68 ÇAMLICA NULL
NULL 45 69 1 NULL
NULL 45 70 2 NULL
3 46 66 NewYork NULL
NULL 46 67 20-8 NULL
NULL 46 68 NULL TEST NULL
NULL 46 69 NULL NULL
NULL 46 70 NULL NULL
First real 20 data of IndexId...
TipId EvrakId IndexId Value KayitTarihi
14 1 388 NULL NULL
14 2 336 NULL NULL
14 3 408 NULL NULL
14 4 83 NULL NULL
14 5 402 NULL NULL
14 6 403 NULL NULL
14 7 404 NULL NULL
14 8 228 NULL NULL
14 9 390 NULL NULL
14 10 419 NULL NULL
14 11 406 NULL NULL
14 12 392 NULL NULL
14 13 389 NULL NULL
14 14 401 NULL NULL
14 15 362 NULL NULL
14 16 407 NULL NULL
14 17 391 NULL NULL
14 18 400 NULL NULL
14 19 242 NULL NULL
14 20 92 NULL NULL
Thanks for your help.

In this solution I added the table variable @tColIndexID, which holds the given IndexIDs for the (currently) four new values. These IndexIDs are than added to each new row:
DECLARE @t1 TABLE(
EvrakID NVARCHAR(100),
DefterNo NVARCHAR(100),
Mezarlik NVARCHAR(100),
SayfaNo NVARCHAR(100),
SatirNo NVARCHAR(100)
)
INSERT INTO @t1 VALUES
('23', '20-8' ,'ÇAMLICA', '1' ,'1')
,('45', '20-8' ,'ÇAMLICA', '1' ,'2')
,('46', '20-8' ,'NULL TEST', NULL ,NULL)
DECLARE @t2 TABLE(
TipID NVARCHAR(100),
EvrakID NVARCHAR(100),
IndexID NVARCHAR(100),
Value NVARCHAR(100),
KayitTarihi NVARCHAR(100)
)
INSERT INTO @t2 VALUES
('1' ,'23' ,'66' ,'JohnMc', NULL)
,('2' ,'45' ,'32' ,'NewYork', NULL)
,('3' ,'46' ,'32' ,'NewYork', NULL)
DECLARE @tColIndexID TABLE(
ColID INT
,IndexID INT
)
INSERT INTO @tColIndexID
VALUES (1, 388)
,(2, 336)
,(3, 408)
,(4, 83);
WITH cte AS(
SELECT t1.EvrakID,
ISNULL(t1.DefterNo,'*NULL#') DefterNo,
ISNULL(t1.Mezarlik,'*NULL#') Mezarlik,
ISNULL(t1.SayfaNo,'*NULL#') SayfaNo,
ISNULL(t1.SatirNo, '*NULL#') SatirNo
FROM @t1 t1
),
cteColsToRows AS(
SELECT EvrakID, ROW_NUMBER() OVER (PARTITION BY EvrakID ORDER BY (SELECT 0)) rn, NewRow
FROM
(SELECT EvrakID,
DefterNo,
Mezarlik,
SayfaNo,
SatirNo
FROM cte) AS nr
UNPIVOT
(NewRow FOR OldCols IN (DefterNo, Mezarlik, SayfaNo, SatirNo)
) AS NewRows
)
INSERT INTO @t2
SELECT NULL TipID,
EvrakID,
t3.IndexID AS IndexId,
CASE WHEN NewRow = '*NULL#' THEN NULL ELSE NewRow END AS Value,
NULL KayitTarihi
FROM cteColsToRows
JOIN @tColIndexID t3 ON t3.ColID = rn
SELECT *
FROM @t2
ORDER BY EvrakID, ISNULL(TipID, 999999)
Result:
TipID EvrakID IndexID Value KayitTarihi
1 23 66 JohnMc NULL
NULL 23 388 20-8 NULL
NULL 23 336 ÇAMLICA NULL
NULL 23 408 1 NULL
NULL 23 83 1 NULL
2 45 32 NewYork NULL
NULL 45 388 20-8 NULL
NULL 45 336 ÇAMLICA NULL
NULL 45 408 1 NULL
NULL 45 83 2 NULL
3 46 32 NewYork NULL
NULL 46 388 20-8 NULL
NULL 46 336 NULL TEST NULL
NULL 46 408 NULL NULL
NULL 46 83 NULL NULL

TipId EvrakId IndexId Value KayitTarihi
NULL 1811417 388 41-2 NULL
NULL 1811417 336 NULL NULL
NULL 1811417 408 9 NULL
NULL 1811417 83 11 NULL
NULL 1811425 388 41-2 NULL
NULL 1811425 336 NULL NULL
NULL 1811425 408 9 NULL
NULL 1811425 83 12 NULL
NULL 1811446 388 41-2 NULL
NULL 1811446 336 NULL NULL
NULL 1811446 408 11 NULL
NULL 1811446 83 1 NULL
This is supposed to be the final state of table 2. As you can see some predefined, already known IndexId values are just repeating themselves for each new EvrakId. This example is for 4 columns only of course. There are 20 columns in my first table and therefore 20 different IndexId's but once you give me the correct algorithm(query) I will be able to edit again for all 20 columns like I did before. Also those 2 example columns are not present here since they are not real data.

Here an example featuring the infamous unpivot :-P . As suggested by you, I nulled all other columns for the time being...
DECLARE @t1 TABLE(
EvrakID NVARCHAR(100),
DefterNo NVARCHAR(100),
Mezarlik NVARCHAR(100),
SayfaNo NVARCHAR(100),
SatirNo NVARCHAR(100)
)
INSERT INTO @t1 VALUES
('23', '20-8' ,'ÇAMLICA', '1' ,'1')
,('45', '20-8' ,'ÇAMLICA', '1' ,'2')
,('46', '20-8' ,'NULL TEST', NULL ,NULL)
DECLARE @t2 TABLE(
TipID NVARCHAR(100),
EvrakID NVARCHAR(100),
IndexID NVARCHAR(100),
Value NVARCHAR(100),
KayitTarihi NVARCHAR(100)
)
INSERT INTO @t2 VALUES
('1' ,'23' ,'66' ,'JohnMc', NULL)
,('2' ,'45' ,'32' ,'NewYork', NULL)
,('3' ,'46' ,'32' ,'NewYork', NULL)
DECLARE @MaxIndexID INT = (SELECT MAX(IndexId) FROM @t2);
WITH cte AS(
SELECT t1.EvrakID,
ISNULL(t1.DefterNo,'*NULL#') DefterNo,
ISNULL(t1.Mezarlik,'*NULL#') Mezarlik,
ISNULL(t1.SayfaNo,'*NULL#') SayfaNo,
ISNULL(t1.SatirNo, '*NULL#') SatirNo
FROM @t1 t1
),
cteColsToRows AS(
SELECT EvrakID, ROW_NUMBER() OVER (PARTITION BY EvrakID ORDER BY (SELECT 0)) rn, NewRow
FROM
(SELECT EvrakID,
DefterNo,
Mezarlik,
SayfaNo,
SatirNo
FROM cte) AS nr
UNPIVOT
(NewRow FOR OldCols IN (DefterNo, Mezarlik, SayfaNo, SatirNo)
) AS NewRows
)
INSERT INTO @t2
SELECT NULL TipID,
EvrakID,
@MaxIndexID + rn AS IndexId,
CASE WHEN NewRow = '*NULL#' THEN NULL ELSE NewRow END AS Value,
NULL KayitTarihi
FROM cteColsToRows
SELECT *
FROM @t2
ORDER BY EvrakID, ISNULL(TipID, 999999)
Result:
TipID EvrakID IndexID Value KayitTarihi
1 23 66 JohnMc NULL
NULL 23 67 20-8 NULL
NULL 23 68 ÇAMLICA NULL
NULL 23 69 1 NULL
NULL 23 70 1 NULL
2 45 32 NewYork NULL
NULL 45 67 20-8 NULL
NULL 45 68 ÇAMLICA NULL
NULL 45 69 1 NULL
NULL 45 70 2 NULL
3 46 32 NewYork NULL
NULL 46 67 20-8 NULL
NULL 46 68 NULL TEST NULL
NULL 46 69 NULL NULL
NULL 46 70 NULL NULL
