I have a dataTable which has the column Device Type,DeviceName and label.
There can be multiple Devices for each deviceType.
So i want to write the stored procedure which will populate label column as 01,02,03,04....
for each DeviceName and DeviceType Combination.
For Example:-
DeviceName DeviceType **Label**
Probe1 1 01
Probe2 1 02
Probe3 1 03
Tank1 2 01
Tank2 2 02
Pump1 3 01
Pump2 3 02
Have a look at using ROW_NUMBER
SELECT *,
ROW_NUMBER() OVER(PARTITION BY DeviceType ORDER BY DeviceName) Label
FROM Table
EDIT
Here is a little UPDATE example then:
DECLARE #Table TABLE(
DeviceName VARCHAR(20),
DeviceType INT,
Label VARCHAR(20)
)
INSERT INTO #Table SELECT 'Probe1',1,''
INSERT INTO #Table SELECT 'Probe2',1,''
INSERT INTO #Table SELECT 'Probe3',1,''
INSERT INTO #Table SELECT 'Tank1',2,''
INSERT INTO #Table SELECT 'Tank2',2,''
INSERT INTO #Table SELECT 'Pump1',3,''
INSERT INTO #Table SELECT 'Pump2',3,''
;WITH Vals AS (
SELECT DeviceName,
DeviceType,
ROW_NUMBER() OVER(PARTITION BY DeviceType ORDER BY DeviceName) Label
FROM #Table
)
UPDATE #Table
SET Label = Vals.Label
FROM #Table t INNER JOIN
Vals ON t.DeviceName = Vals.DeviceName
AND t.DeviceType = Vals.DeviceType
SELECT *
FROM #Table
With the assumption that DeviceName is unique, you can use ROW_NUMBER like this:
DECLARE #Data TABLE (DeviceName VARCHAR(50), DeviceType INTEGER, Label CHAR(2))
INSERT #Data VALUES ('Probe1', 1, '')
INSERT #Data VALUES ('Probe2', 1, '')
INSERT #Data VALUES ('Probe3', 1, '')
INSERT #Data VALUES ('Tank1', 2, '')
INSERT #Data VALUES ('Tank2', 2, '')
INSERT #Data VALUES ('Pump1', 3, '')
INSERT #Data VALUES ('Pump2', 3, '')
UPDATE d
SET d.Label = RIGHT('0' + CAST(x.RowNo AS VARCHAR(2)), 2)
FROM #Data d
JOIN (
SELECT DeviceName, ROW_NUMBER() OVER (PARTITION BY DeviceType ORDER BY DeviceName) AS RowNo
FROM #Data
) x ON d.DeviceName = x.DeviceName
SELECT * FROM #Data

I would like to get the desired output marked in green
the data points for each id get put into a single cell
Basically take all the events that have happened with A and attach it in the same order
Use Stuff Function:
DECLARE #tblTest AS Table(
ID INT,
EVENT VARCHAR(5)
)
INSERT INTO #tblTest VALUES
(1,'A'),
(1,'A'),
(1,'C'),
(2,'A'),
(2,'B'),
(2,'C')
SELECT DISTINCT
T1.ID,
STUFF
(
(SELECT '' + convert(varchar(10), T2.EVENT, 120)
FROM #tblTest T2
where T1.ID = T2.ID
FOR XML PATH (''))
, 1, 0, '') AS EVENT
FROM #tblTest T1
You can use FOR XML:
SELECT DISTINCT
ID,
(SELECT [EVENT] +''
FROM YourTable
WHERE ID = y.ID
FOR XML PATH('')
) as [EVENT]
FROM YourTable y
Output:
ID EVENT
1 AABCD
2 AABBCC
You can use UDF to do so as follows:
CREATE TABLE t(
id INT,
col CHAR(1)
);
INSERT INTO t VALUES (1,'a');
INSERT INTO t VALUES (1,'b');
INSERT INTO t VALUES (1,'c');
INSERT INTO t VALUES (1,'d');
INSERT INTO t VALUES (2,'e');
INSERT INTO t VALUES (2,'f');
INSERT INTO t VALUES (3,'g');
INSERT INTO t VALUES (4,'h');
The UDF (User defined function) -
USE [t]
GO
CREATE FUNCTION dbo.ConcatenateCols(#Id INT)
RETURNS VARCHAR(MAX)
AS
BEGIN
DECLARE #RtnStr VARCHAR(MAX)
SELECT #RtnStr = COALESCE(#RtnStr + '','') + col
FROM dbo.t
WHERE id = #Id AND col > ''
RETURN #RtnStr
END
GO
Finally the query and result:
SELECT id, dbo.ConcatenateCols(id) AS Cols -- UDF - ConcatenateCols(id)
FROM t GROUP BY Id
CREATE TABLE #temp(Id INt,Event Nvarchar(25))
INSERT INTO #temp
SELECT 1,
'A'
UNION ALL
SELECT 1,
'A'
UNION ALL
SELECT 1,
'B'
UNION ALL
SELECT 1,
'C'
UNION ALL
SELECT 1,
'D'
UNION ALL
SELECT 2,
'A'
UNION ALL
SELECT 2,
'A'
UNION ALL
SELECT 2,
'B'
UNION ALL
SELECT 2,
'B'
UNION ALL
SELECT 2,
'C'
UNION ALL
SELECT 2,
'C'
SELECT DISTINCT ID,
(SELECT [EVENT] +''
FROM #temp
WHERE ID = y.ID
FOR XML PATH('') ) AS [EVENT]
FROM #temp y
How can I generate custom ids upon inserting records base on a condition? For example, I have a donor database program which accepts donations from non-alumni and alumni. Custom id from an alumni should start on A00001 and for non-alumni is N00001. And to note, the record that will be inserted will come from another table which records came from an excel file.
Any help or clarifications would be appreciated.
Something like this perhaps?
DECLARE #Table TABLE ( ID VARCHAR(20) );
-- Non alumni
INSERT INTO #Table
( ID )
VALUES ( 'N00011' )
INSERT INTO #Table
( ID )
VALUES ( 'N00012' )
INSERT INTO #Table
( ID )
VALUES ( 'N00013' )
-- Alumni
INSERT INTO #Table
( ID )
VALUES ( 'A00011' )
INSERT INTO #Table
( ID )
VALUES ( 'A00012' )
INSERT INTO #Table
( ID )
VALUES ( 'A00013' )
-- Insert Alumni
INSERT INTO #Table
( ID
)
SELECT 'A' + RIGHT('00000'
+ CAST(MAX(RIGHT(ID, LEN(ID) - 1)) + 1 AS VARCHAR(10)),
5)
FROM #Table
WHERE LEFT(ID, 1) = 'A'
-- Insert Non Alumni
INSERT INTO #Table
( ID
)
SELECT 'N' + RIGHT('00000'
+ CAST(MAX(RIGHT(ID, LEN(ID) - 1)) + 1 AS VARCHAR(10)),
5)
FROM #Table
WHERE LEFT(ID, 1) = 'N'
i have the data like this:
CODE_VD
N_10_19_xxx
N_0_3_xxx
N_121_131_xxx
N_100_120_xxx
N_80_90_xxx
N_20_29_xxx
as you can see i need to sort just the first number after N_,i don't know how can i get this number.
i have tried with susbsting(CODE_VD,2,3) but not exactly what i expected.
i want to get this:
CODE_VD
N_0_3_xxx
N_10_19_xxx
N_20_29_xxx
N_80_90_xxx
N_100_120_xxx
N_121_131_xxx
how can i do that ?
DECLARE #MyTable TABLE
(
CODE_VD VARCHAR(20)
)
INSERT INTO #MyTable
( CODE_VD )
VALUES
('N_10_19_xxx'),
('N_0_3_xxx'),
('N_121_131_xxx'),
('N_100_120_xxx'),
('N_80_90_xxx'),
('N_20_29_xxx');
SELECT * FROM
(
SELECT
*,
CONVERT(INT,
SUBSTRING(mt.CODE_VD,
3,
CHARINDEX('_', mt.CODE_VD, 3) - 3)) ConvCol
FROM #MyTable mt
) mt
ORDER BY mt.ConvCol
I converted to int to get the sort to work correctly, because 100 > 20
SELECT SUBSTRING(CODE_VD,3, CHARINDEX('_',CODE_VD, 3)-3)
declare #t Table (CODE_VD VARCHAR(MAX))
INSERT INTO #t (CODE_VD)VALUES ('N_10_19_xxx')
INSERT INTO #t (CODE_VD)VALUES ('N_0_3_xxx')
INSERT INTO #t (CODE_VD)VALUES ('N_121_131_xxx')
INSERT INTO #t (CODE_VD)VALUES ('N_100_120_xxx')
;WITH
sorted
AS
(
SELECT
*,
ROW_NUMBER() OVER (PARTITION BY SUBSTRING(CODE_VD,3, CHARINDEX('_',CODE_VD, 3)-3) ORDER BY CODE_VD) AS sequence_id
FROM
#t
)
SELECT
CODE_VD
FROM
sorted
WHERE
sequence_id = 1
I have a table like this
Declare #Temp Table(Data VarChar(20))
Insert Into #Temp Values('F_200_100_')
Insert Into #Temp Values('F_50_')
Insert Into #Temp Values('F_30_')
Insert Into #Temp Values('F_50_10')
Insert Into #Temp Values('F_100_')
Insert Into #Temp Values('F_20_')
I want my output to be distinct values of the numbers extracted from data column
20
30
50
100
200
I have tried using patindex but I am looking for ideas
tried this
select
Left(
SubString(Data, PatIndex('%[0-9]%', Data), 8000),
PatIndex('%[^0-9]%', SubString(Data, PatIndex('%[0-9]%', Data), 8000) + 'X')-1
)
from #temp

How to do that in Sql Server 2008 ?
I dont beleive a PIVOT is what you are looking for here.
From what I can see you are looking at using the entries in order to generate the rows?
Also, PIVOTs make use of aggregate functions, so I cant see this happening.
What you can try, is something like
DECLARE #Table TABLE(
Brand VARCHAR(10),
Product VARCHAR(10)
)
INSERT INTO #Table SELECT 'A','X '
INSERT INTO #Table SELECT 'A','XX'
INSERT INTO #Table SELECT 'A','XXX'
INSERT INTO #Table SELECT 'B','Y'
INSERT INTO #Table SELECT 'B','YY'
INSERT INTO #Table SELECT 'C','Z'
;WITH Vals AS (
SELECT *,
ROW_NUMBER() OVER(PARTITION BY Brand ORDER BY (SELECT NULL)) RID
FROM #Table
)
, RIDs AS (
SELECT DISTINCT
RID
FROM Vals
)
SELECT vA.Product [A],
vB.Product [B],
vC.Product [C]
FROM RIDs r LEFT JOIN
Vals vA ON r.RID = vA.RID
AND vA.Brand = 'A' LEFT JOIN
Vals vB ON r.RID = vB.RID
AND vB.Brand = 'B' LEFT JOIN
Vals vC ON r.RID = vC.RID
AND vC.Brand = 'C'
I know it is a late entry, but here is a different approach to solve it:
DECLARE #Table TABLE(Brand VARCHAR(10), Product VARCHAR(10))
INSERT INTO #Table SELECT 'A','X '
INSERT INTO #Table SELECT 'A','XX'
INSERT INTO #Table SELECT 'A','XXX'
INSERT INTO #Table SELECT 'B','Y'
INSERT INTO #Table SELECT 'B','YY'
INSERT INTO #Table SELECT 'C','Z'
SELECT [A],[B],[C] FROM (
SELECT row_number() over (partition by brand order by product) rn,
Product, brand FROM #table
) as p
PIVOT(
MAX(product) for Brand in ([A],[B],[C])
)as pvt
