I have a link and I want to substring it into many pieces to get numbers
example:-
&OR=-12&MR=24560&MM=20&Mx=110&EOW=1&OW=50&OV=12&CV=-1
I want the -12 , 24560 , 20 , ... etc.
and I did it using this code
DECLARE #strprog AS NVARCHAR(MAX)--,#strLM AS NVARCHAR(20),#strLOW AS NVARCHAR(20),#strLOR AS NVARCHAR(20),#strLCR AS NVARCHAR(20),
DECLARE #OR AS SMALLINT, #MR AS SMALLINT, #MM AS SMALLINT, #Mx AS SMALLINT, #EOW AS SMALLINT, #OW AS SMALLINT, #OV AS SMALLINT, #CV AS SMALLINT

SELECT #CV
The problem is the link could be cut off at any place
example:-
&OR=-12&MR=24560&MM=20
how can I stop cutting when it reach an end ?
any help ?
You can use XML type in MSSQL server to separate the string into lines and get a table with attribute and value columns. Then you can select any attribute you need from this rowset:
DECLARE #strprog AS NVARCHAR(MAX);
SET #strprog='WorkFlow/WFmain.aspx?sservice=WFAppraisalManage&showrep=1&
applyRole=0&DisableApproval=1&grbCompQuest=1&EnablecompletionChk=1
&MaxCompletionNo=110&ProficiencyValidation=0&objresulttxt=0
&OR=-12&MR=24560&MM=20&Mx=110&EOW=1&OW=50&OV=12&CV=-1';
DECLARE #xml as XML;
SET #xml = cast(('<X>'+replace(#strprog,'&' ,'</X><X>')+'</X>') as xml);
WITH T2 as
(
SELECT N.value('.', 'varchar(1000)') as val FROM #xml.nodes('X') as T(N)
)
SELECT LEFT(val,CHARINDEX('=',val)-1) as attribute,
SUBSTRING(val,CHARINDEX('=',val)+1,1000) as value
FROM T2;
You get following row set:
╔═══════════════════════════════╦═══════════════════╗
║ attribute ║ value ║
╠═══════════════════════════════╬═══════════════════╣

All your substrings are preempted by an equal sign and finished by an ampersand.
Why don't you create a loop to get the string, get value from first equal to the ampersand, drop the part of the string processed from the string and continue doing the same with the rest of the string??
You can check the CHARINDEX of each token before setting each variable to see if that token even exists at all in the string.

I have tried looking for a solution to my problem using things such as Pivot, but they do not seem to give the output for which I am looking as they appear to map specific values in a row to a column.
I have two columns, the first which contains a "key" field and the second which is changing data. e.g.
╔══════════╦══════════════════╗
║ Project ║ Location ║
╠══════════╬══════════════════╣
║ ProjectA ║ \\Server1\Share1 ║
║ ProjectA ║ \\Server2\Share1 ║
║ ProjectB ║ \\Server6\Share2 ║
║ ProjectB ║ \\Server1\Share2 ║
║ ProjectB ║ \\Server2\Share3 ║
║ ProjectC ║ \\Server8\Share2 ║
║ ProjectD ║ \\Server5\Share9 ║
║ ProjectD ║ \\ServerX\ShareY ║
╚══════════╩══════════════════╝
The output that I am trying to achieve is as follows:
╔══════════╦══════════════════╦══════════════════╦══════════════════╦═════════╦══════════╦═════════╗
║ Project ║ Column1 ║ Column2 ║ Column3 ║ Column4 ║ Column5 ║ ColumnX ║
╠══════════╬══════════════════╬══════════════════╬══════════════════╬═════════╬══════════╬═════════╣
║ ProjectA ║ \\Server1\Share1 ║ \\Server2\Share1 ║ NULL ║ NULL ║ NULL ║ ║
║ ProjectB ║ \\Server1\Share2 ║ \\Server2\Share3 ║ \\Server6\Share2 ║ NULL ║ NULL ║ ║
║ ProjectC ║ \\Server8\Share2 ║ NULL ║ NULL ║ NULL ║ NULL ║ ║
║ ProjectD ║ \\Server5\Share9 ║ \\ServerX\ShareY ║ NULL ║ NULL ║ NULL ║ ║
╚══════════╩══════════════════╩══════════════════╩══════════════════╩═════════╩══════════╩═════════╝
If there is no data for the column then it will be NULL.
The number of distinct values in the location column is dynamic and the desired output is a generic column name, with the distinct location value beside the corresponding Project value.
Hopefully someone can help me with this problem as it is driving me mad!
Thanks in advance.

Warning:
This solution assume that it will be max 6 column, you can add more for example up to 20.

Credit goes to #lad2025.
I am using Server2005 so these are the modifications that I had to make to get this to work for me:
Couldn't declare and assign a variable in the same line. #max INT = 0;
CONCAT function doesn't exist so replaced with + between the parameters. ', ' + '[' + convert(varchar, c.n) + '] AS Column' + c.n
c.n is of type bigint so I had to CONVERT it to VARCHAR - CONVERT(VARCHAR, c.n)
When generating the table on which to pivot, a GROUP BY needs to be provided otherwise the data appears in a strange column number.
Without GROUP BY
Without the GROUP BY as more data is in the initial #mytable the results display in columns that are not sequential.

Good Day,
I am busy creating a tax document for discount entries out of our debtors transaction table. One of the requirements is that the discount amount must indicate to which transaction it relates. This information is available but I do not know how to use it because it is in a single delimited text field. The table looks as follows.
╔═════════╦════════════╦══════╦════════╦═══════════╦══════════════════════════════════════════╗

In the column cAllocs you have the information that links the lines with each other. It has three indicators
I - the line in this table that it links to
A - the amount of the link transaction
D - the date of the transaction
It can have only one set of these or many sets delimited with a pipe character.
I want to end up with a table that has only the entries with Id "DS" but giving me the reference column value of the lines it links to in a single column (they can be delimited by comma)
So from the above table I would like to get this result.

Thanks for any replies
You can create a function that handles string manipulation and retrieves the data at the same time. Try this one below:
CREATE FUNCTION [dbo].[GetReferenceFromCAllocs](#cAllocs VARCHAR(MAX))RETURNS VARCHAR(MAX)AS
BEGIN
DECLARE #val AS VARCHAR(MAX)
DECLARE #ch AS CHAR(1)
DECLARE #result AS VARCHAR(MAX)
DECLARE #returnValue AS VARCHAR(MAX)
SET #val = #cAllocs
SET #result = ''
SET #returnValue = ''
DECLARE #idx INT
SET #idx = 1
WHILE #idx < LEN(#val)
BEGIN
SET #ch = SUBSTRING(#val,#idx,1)
IF(#ch = 'I')
BEGIN
DECLARE #idx2 INT
DECLARE #temp VARCHAR(5)
SET #temp = #ch
SET #idx2 = #idx + 1
SET #ch = SUBSTRING(#val,#idx2,1)
WHILE #ch <> ';'
BEGIN
SET #temp = #temp + #ch
SET #idx2 = #idx2 + 1
SET #ch = SUBSTRING(#val,#idx2,1)
END
SET #idx = #idx2
SET #result = #result + #temp + ';'
END
ELSE
SET #idx = #idx + 1
END
SET #idx = 1
WHILE #idx < LEN(#result)
BEGIN
SET #ch = SUBSTRING(#val,#idx,1)
IF(#ch = '=')
BEGIN
SET #temp = ''
SET #idx2 = #idx + 1
SET #ch = SUBSTRING(#result,#idx2,1)
WHILE #ch <> ';'
BEGIN
SET #temp = #temp + #ch
SET #idx2 = #idx2 + 1
SET #ch = SUBSTRING(#result,#idx2,1)
END
SET #idx = #idx2
DECLARE #tempValue AS VARCHAR(10)
SET #tempValue = ''
SELECT #tempValue = Reference FROM YOUR_TABLE
WHERE AutoIdx = #temp
SET #returnValue = #returnValue + #tempValue + ','
END
ELSE
SET #idx = #idx + 1
END
RETURN SUBSTRING(#returnValue,1, LEN(#returnValue)-1)
END
--EDIT: The function above will get all data with I as it's prefix:
E.g:
Passed Value: I=4;A=99;D=20140730|I=3;A=1;D=20140730
Result Value: I=4;I=3;
After that, it queries the corresponding Reference with AutoIdx 4 and 3; then returns it in a format as specified in your question.
Then, run this sql:
SELECT
yt.TxDate,
yt.Id,
yt.Amount,
yt.Reference,
dbo.GetReferenceFromCAllocs(yt.cAllocs) AS MatchedTo
FROM YOUR_TABLE yt
WHERE yt.Id = 'DS'
Hope this would work. Just adjust the SQL codes to optimize it. I'm in a hurry so I used safest values (such as VARCHAR(MAX)).
I have a table which must be with next structure:

╚════╩═══════╩════╩═════╝
where:
1) record with id=55 is a parent record and
2) records with id=56, id=57 (listed in a column and separated with semicolon) are child records
At first table is next
╔════╦═══════╦════╦═════╗

╚════╩═══════╩════╩═════╝
so I must to update table such as first table
For this purpose I created next CTE
with My_CTE(PId, a, c, b, newC, inde) as
(
select
ST.PID, ST.a, ST.c, ST.b, res.C,
ind = case
when ST.a != ''
then (dense_rank() over(order by ST.a))
end
from STable as ST
outer APPLY
fnSplit(ST.a) as res
where (not(ST.a = '') or not(ST.c = ''))
)
UPDATE STable
Set b =
cte.inde
From STable as st
Join My_CTE as cte on st.PID = cte.PId;
GO
As a result I have table with next values

So I need to set values in column b for children records.
Maybe it could be established in select statement of MyCTE?

I want to write stored procedure which will select data from Table1 and data from another table depending upon value of column tableName and columnName in Table1.
I want data in following format:

Try temporary table .
look at here : http://www.sqlteam.com/article/temporary-tables
You will need a dynamic sql to get such a select. Check out the link http://www.mssqltips.com/sqlservertip/1160/execute-dynamic-sql-commands-in-sql-server/
EDIT:
The following code should do the trick.
I have assumed that the column Col1 in Table1 is of type int.
I have used Temp table to generate the required table. You can replace it will your table as per your convenience. Also I have used #table1 which you can replace with your Table1.
Also this might not be very good in terms of performance but this is the best I could come up with right now.
declare #count int, #Query VARCHAR(5000), #counter int, #tableName VARCHAR(50), #ColumnName VARCHAR(50), #Col1 INT, #Col2 VARCHAR(50)
select #count = count(0) from #table1
SET #counter = 1
CREATE TABLE #table4
(
Col1 INT,
Col2 VARCHAR(50),
List VARCHAR(50)
)
WHILE #counter <= #count
BEGIN
SELECT #tableName = TableName, #ColumnName = columnName, #Col1 = Col1, #Col2 = Col2 FROM #Table1 WHERE Col1 = #counter
SELECT #Query = 'INSERT INTO #table4 (Col1 , Col2) VALUES (' + CONVERT(varchar(50),#Col1) + ', ''' + #Col2 + ''')'
EXEC (#Query)
SELECT #Query = ''
IF ISNULL(#tableName, '') != '' AND ISNULL(#ColumnName, '') != ''
BEGIN
SELECT #Query = 'UPDATE #table4 SET LIST = STUFF((SELECT '','' + CONVERT(VARCHAR(50), ' + #ColumnName + ') FROM ' + #tableName + ' FOR XML PATH('''')),1,1,'''') WHERE Col1 = ' + CONVERT(varchar(50),#Col1)
EXEC (#Query)
END
SET #counter = #counter + 1
END
SELECT * FROM #table4
Hope this helps
Answer edited for incorporating n no of rows
CODE
drop table #temp1
declare #tabletemp as varchar (10)

SQL Server: Examples of PIVOTing String data

Closed 8 years ago.
I have a table with 2 columns plateno and alerts.
table Data
plateno alerts
A 1
B 2
C 2
A 3
B 2
A 4
A 1
Now I want to get the result like this:
alerts-> 1 2 3 4
---------------------------
A 2 0 1 1
B 0 2 0 0
C 0 1 0 0
I mean 'A' has two alerts of type '1',1 alert of type '3' and '4'...and so on..
Here is my query I am trying with
Select count(alert)
from mytable
group by plateno
Try this :-
Select plateno,[1],[2],[3],[4]
from
(
Select plateno,alerts from Sample
)p
pivot
(
count(alerts)
for alerts in ([1],[2],[3],[4])
)pvt
Demo Here
If you have unknown number of values for the column Alert, a dynamic sql is much more preferred,
DECLARE #colList AS NVARCHAR(MAX), #sqlStatement AS NVARCHAR(MAX)
SELECT #colList = STUFF((SELECT DISTINCT ',' + QUOTENAME(alerts)
FROM data
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)') ,1,1,'')
SET #sqlStatement = 'SELECT plateno,' + #colList + '
FROM
(
SELECT plateno, alerts
FROM data
) dta
pivot
(
COUNT(alerts)
FOR alerts IN (' + #colList + ')
) pvt '
EXECUTE(#sqlStatement)
