How can I get the value from the sixth field in the following column? I am trying to get the 333 field:
ORGPATHTXT
2123/2322/12323/111/222/333/3822
I believe I have to use select substring, but am unsure how to format the query
Assuming SQL Server
The easiest way I can think of is create a Split function that splits based on '/' and you extract the sixth item like below
declare #text varchar(50) = '2123/2322/12323/111/222/333/3822'
select txt_value from fn_ParseText2Table(#text, '/') t where t.Position = 6
I used the function in this url. See it worked at SQLFiddle
Try this - for a string variable or wrap into a function to use with a select query (Sql-Demo)
Declare #s varchar(50)='2123/2322/12323/111/222/333/3822'
Select #s = right(#s,len(#s)- case charindex('/',#s,1) when 0 then len(#s)
else charindex('/',#s,1) end)
From ( values (1),(2),(3),(4),(5)) As t(num)
Select case when charindex('/',#s,1)>0 then left(#s,charindex('/',#s,1)-1)
else #s end
--Results
333
I'd like to offer a solution that uses CROSS APPLY to split up any delimited string in MSSQL and ROW_NUMBER() to return the 6th element. This assumes you have a table with ORGPATHTXT as a field (it can easily be converted to work without the table though):
SELECT ORGPATHTXT
FROM (
SELECT
Split.a.value('.', 'VARCHAR(100)') AS ORGPATHTXT,
ROW_NUMBER() OVER (PARTITION BY ID ORDER BY (SELECT 1)) RN
FROM
(SELECT ID, CAST ('<M>' + REPLACE(ORGPATHTXT, '/', '</M><M>') + '</M>' AS XML) AS String
FROM MyTable
) AS A
CROSS APPLY String.nodes ('/M') AS Split(a)
) t
WHERE t.RN = 6;
Here is some sample Fiddle to go along with it.
Good luck.
For sql, you can use
declare #string varchar(65) = '2123/2322/12323/111/222/333/3822'
select substring(string,25,27) from table_name
If you are using MySQL, then you can use:
select substring_index(orgpathtxt, '/', 6)
Let me just say that it is less convenient in most other databases.
Also you can use option with dynamic management function sys.dm_fts_parser
DECLARE #s nvarchar(50) = '2123/2322/12323/111/222/333/3822'
SELECT display_term
FROM sys.dm_fts_parser('"'+ #s + '"', 1033, NULL, 0)
WHERE display_term NOT LIKE 'nn%' AND occurrence = 6

I have a field which is a concatenation of single letters. I am trying to order these strings within a view. These values can't be hard coded as there are too many. Is someone able to provide some guidance on the function to use to achieve the desired output below? I am using MSSQL.
Current output
CustID | Code
123 | BCA
Desired output
CustID | Code
123 | ABC
I have tried using a UDF
CREATE FUNCTION [dbo].[Alphaorder] (#str VARCHAR(50))
returns VARCHAR(50)
BEGIN
DECLARE #len INT,
#cnt INT =1,
#str1 VARCHAR(50)='',
#output VARCHAR(50)=''
SELECT #len = Len(#str)
WHILE #cnt <= #len
BEGIN
SELECT #str1 += Substring(#str, #cnt, 1) + ','
SET #cnt+=1
END
SELECT #str1 = LEFT(#str1, Len(#str1) - 1)
SELECT #output += Sp_data
FROM (SELECT Split.a.value('.', 'VARCHAR(100)') Sp_data
FROM (SELECT Cast ('<M>' + Replace(#str1, ',', '</M><M>') + '</M>' AS XML) AS Data) AS A
CROSS APPLY Data.nodes ('/M') AS Split(a)) A
ORDER BY Sp_data
RETURN #output
END
This works when calling one field
ie.
Select CustID, dbo.alphaorder(Code)
from dbo.source
where custid = 123
however when i try to apply this to top(10) i receive the error
"Invalid length parameter passed to the LEFT or SUBSTRING function."
Keeping in mind my source has ~4million records, is this still the best solution?
Unfortunately i am not able to normalize the data into a separate table with records for each Code.
This doesn't rely on a id column to join with itself, performance is almost as fast
as the answer by #Shnugo:
SELECT
CustID,
(
SELECT
chr
FROM
(SELECT TOP(LEN(Code))
SUBSTRING(Code,ROW_NUMBER() OVER(ORDER BY (SELECT NULL)),1)
FROM sys.messages) A(Chr)
ORDER by chr
FOR XML PATH(''), type).value('.', 'varchar(max)'
) As CODE
FROM
source t
First of all: Avoid loops...
You can try this:
DECLARE #tbl TABLE(ID INT IDENTITY, YourString VARCHAR(100));
INSERT INTO #tbl VALUES ('ABC')
,('JSKEzXO')
,('QKEvYUJMKRC');
--the cte will create a list of all your strings separated in single characters.
--You can check the output with a simple SELECT * FROM SeparatedCharacters instead of the actual SELECT
WITH SeparatedCharacters AS
(
SELECT *
FROM #tbl
CROSS APPLY
(SELECT TOP(LEN(YourString)) ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) FROM master..spt_values) A(Nmbr)
CROSS APPLY
(SELECT SUBSTRING(YourString,Nmbr,1))B(Chr)
)
SELECT ID,YourString
,(
SELECT Chr As [*]
FROM SeparatedCharacters sc1
WHERE sc1.ID=t.ID
ORDER BY sc1.Chr
FOR XML PATH(''),TYPE
).value('.','nvarchar(max)') AS Sorted
FROM #tbl t;
The result
ID YourString Sorted
1 ABC ABC
2 JSKEzXO EJKOSXz
3 QKEvYUJMKRC CEJKKMQRUvY
The idea in short
The trick is the first CROSS APPLY. This will create a tally on-the-fly. You will get a resultset with numbers from 1 to n where n is the length of the current string.
The second apply uses this number to get each character one-by-one using SUBSTRING().
The outer SELECT calls from the orginal table, which means one-row-per-ID and use a correalted sub-query to fetch all related characters. They will be sorted and re-concatenated using FOR XML. You might add DISTINCT in order to avoid repeating characters.
That's it :-)
Hint: SQL-Server 2017+
With version v2017 there's the new function STRING_AGG(). This would make the re-concatenation very easy:
WITH SeparatedCharacters AS
(
SELECT *
FROM #tbl
CROSS APPLY
(SELECT TOP(LEN(YourString)) ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) FROM master..spt_values) A(Nmbr)
CROSS APPLY
(SELECT SUBSTRING(YourString,Nmbr,1))B(Chr)
)
SELECT ID,YourString
,STRING_AGG(sc.Chr,'') WITHIN GROUP(ORDER BY sc.Chr) AS Sorted
FROM SeparatedCharacters sc
GROUP BY ID,YourString;
Considering your table having good amount of rows (~4 Million), I would suggest you to create a persisted calculated field in the table, to store these values. As calculating these values at run time in a view, will lead to performance problems.
If you are not able to normalize, add this as a denormalized column to the existing table.
I think the error you are getting could be due to empty codes.
If LEN(#str) = 0
BEGIN
SET #output = ''
END
ELSE
BEGIN
... EXISTING CODE BLOCK ...
END
I can suggest to split string into its characters using referred SQL function.
Then you can concatenate string back, this time ordered alphabetically.
Are you using SQL Server 2017? Because with SQL Server 2017, you can use SQL String_Agg string aggregation function to concatenate characters splitted in an ordered way as follows
select
t.CustId, string_agg(strval, '') within GROUP (order by strval)
from CharacterTable t
cross apply dbo.SPLIT(t.code) s
where strval is not null
group by CustId
order by CustId
If you are not working on SQL2017, then you can follow below structure using SQL XML PATH for concatenation in SQL
select
CustId,
STUFF(
(
SELECT
'' + strval
from CharacterTable ct
cross apply dbo.SPLIT(t.code) s
where strval is not null
and t.CustId = ct.CustId
order by strval
FOR XML PATH('')
), 1, 0, ''
) As concatenated_string
from CharacterTable t
order by CustId
I have many different types of string, but they all follow the two same patterns:
ABC123-S-XYZ789
ABC123-P-XYZ789
QUESTION 1:
I know how I can extract the first part: ABC123
But how do I extract the second part??? XYZ789
QUESTION 2:
I can't tell beforehand if the string follows the -S- pattern or the -P- pattern, it can be different each time. Anyone who know how I can solve this?
Thanks! / Sophie
You can try following code:
SELECT CASE WHEN #a LIKE '%-S-%' THEN right(#a, CHARINDEX('-S-', #a)-1)
WHEN #a LIKE '%-P-%' THEN right(#a, CHARINDEX('-P-', #a)-1)
ELSE NULL END AS 'ColName'
FROM tablename
Is this what you need?
DECLARE #Input VARCHAR(100) = 'ABC123-S-XYZ789'
SELECT
FirstPart = SUBSTRING(
#Input,
1,
CHARINDEX('-', #Input) - 1),
SecondPart = SUBSTRING(
#Input,
LEN(#Input) - CHARINDEX('-', REVERSE(#Input)) + 2,
100),
Pattern = CASE
WHEN #Input LIKE '%-S-%' THEN 'S'
WHEN #Input LIKE '%-P-%' THEN 'P' END
You can use parsename() if the string has always this kind of parts such as ABC123-S-XYZ789
select col, parsename(replace(col, '-', '.'), 1)
However, the parsename() requires the SQL Server+12 if not then you can use reverse()
select col, reverse(left(reverse(col), charindex('-', reverse(col))-1))
If you're using SQL Server 2016 or newer, you can use STRING_SPLIT
CREATE TABLE #temp (string VARCHAR(100));
INSERT #temp VALUES ('ABC123-S-XYZ789'),('ABC123-P-XYZ789');
SELECT *, ROW_NUMBER() OVER (PARTITION BY string ORDER BY string)
FROM #temp t
CROSS APPLY STRING_SPLIT(t.string, '-');
I can't tell beforehand if the string folllows the -S- pattern or the -P- pattern
You can then use a CTE to get a specific part of the string:
WITH cte AS (
SELECT *, ROW_NUMBER() OVER (PARTITION BY string ORDER BY string) rn
FROM #temp t
CROSS APPLY STRING_SPLIT(t.string, '-')
)
SELECT * FROM cte WHERE rn = 2
I have data in database an example of data below
folder/subfolder/file/doc
folder/subfolder/doc
how do I get the 1st instance of characters from between the '/'
I want to extract 'folder/subfolder'
I have tried the following but not what I need. this gets 'folder/'
LEFT([Cat], CHARINDEX('/', [Cat]) ) as 'doc_cat',
and the below gets the last part
RIGHT([Cat], CHARINDEX('/', [Cat]) ) as 'doc_cat2',
I want to get the 1st part of and second part of string
Here is one method:
select left(doc_cat_1, charindex('/', doc_cat_1) - 1)
from t cross apply
(select stuff(cat, 1, charindex('/', cat), '') as doc_cat_1
) v1;
The string handling capabilities of SQL Server are pretty lousy. Apply at least makes it easier to handle intermediate results.
You can use LEFT and CHARINDEX
LEFT([Cat],charindex('/',[Cat],charindex('/',[Cat])+1)-1) AS 'doc_cat'
One more way to accomplish using XML -
declare #s table(patterns nvarchar(100))
insert into #s
values ('folder/subfolder/file/doc'), ('folder/subfolder/doc'),('folder/subfolder')
select cast(concat('<x>', REPLACE(patterns, '/', '</x><x>'), '</x>') as xml).value('/x[1]','varchar(100)') + '/'
+ cast(concat('<x>', REPLACE(patterns, '/', '</x><x>'), '</x>') as xml).value('/x[2]','varchar(100)')
from #s
If you're on SQL 2016 or newer, you could use STRING_SPLIT()
WITH cte AS (
SELECT cat, value, ROW_NUMBER() OVER (PARTITION BY cat ORDER BY cat) rn
FROM someTable CROSS APPLY
STRING_SPLIT(cat,'/')
)
SELECT cat, value FROM cte WHERE rn = 2;
The advantage here is that rn could be any number you need.
Fiddle here.
I need to update the url stored in a column.
My columns have values like this:
https://www.site.sharepoint.com/sites/test/AB-19-CALL
I want to update this URL to:
https://www.site.sharepoint.com/sites/test/CALL-AB-19
To get the last part which is AB-19-CALL, I used the below query
SELECT
SUBSTRING(urlcompte, LEN(urlcompte) - CHARINDEX('/', REVERSE(urlcompte)) + 2, LEN(urlcompte)),
UrlCompte
FROM
tblAccount
Now to split and reverse the AB-19-call I would again need to use the entire query above and then select substring using -
Is there an easier way to do this?
In C# we can do something like this:
urlCompte.Split('-')[2] + urlCompte.Split('-')[0] + urlCompte.Split('-')[1]
Is there a way in SQL Server to split the column and access different parts of it?
This would work to split the string parts -
DECLARE #txt NVARCHAR(500)= 'https://www.site.sharepoint.com/sites/test/AB-19-CALL';
SELECT value
FROM STRING_SPLIT(REVERSE(SUBSTRING(REVERSE(#txt), 1, CHARINDEX('/', REVERSE(#txt))-1)), '-');(substring(reverse(#txt),1,charindex('/',reverse(#txt))-1)),'-')
If you are so lucky to be using SQL Server 2017 you can use for string_agg function for concatenating splitted string pieced with SQL string_split function
Here is the script to change the order of last part in your url
declare #url varchar(100) = 'CALL-AB-19'
select
string_agg(value,'-') within group (order by rn desc)
from (
select
value, row_number() over (order by #url) as rn
from STRING_SPLIT( #url , '-' )
) t
If you want to apply this solution as a set based solution on your table rows with a single SELECT statement, you can execute following SQL
select
id, string_agg(value,'-') within group (order by rn desc)
from (
select
id, value, row_number() over (partition by id order by url) as rn
from urlList
cross apply STRING_SPLIT( url , '-' )
) t
group by id
I assume, in your table urlList, you have a PK field id
If you don't use SQL Server 2016 for split function and SQL Server 2017 for string aggregate function, you can search the web for split string function samples. And using FOR XML Path to concatenate string parts, you can build a solution with the help of CTE expression as follows
;with cte as (
select
urlList.id,
urlList.url,
s.id sid,
s.val
from urlList
cross apply dbo.split(url,'-' ) s
)
SELECT
distinct
id,
STUFF(
(
SELECT
'-' + u.val
FROM cte as u
where u.id = cte.id
Order By sid desc
FOR XML PATH('')
), 1, 1, ''
) As newurl
FROM cte
Please note that the referred split function returns an id named numeric field which shows the order of the splitted piece. So while concatenating I use an "order by" clause on the same field this time in descending order
If someone is using SQL server 2012 or older version then it can be possible by this way:
DECLARE #URL VARCHAR(100) = 'https://www.site.sharepoint.com/sites/test/AB-19-CALL'
SELECT TOP 1 dbo.[Reversedata](DATA, '-')
FROM (SELECT * FROM dbo.Splitter(#URL, '/') as t) as tt order by Id desc
In above code I have used two functions:
1) Splitter : To split the string (https://ole.michelsen.dk/blog/split-string-to-table-using-transact-sql.html)
2) Reversedata: To reverse the data (http://picnicerror.net/development/sql-server/reverse-order-words-string-sql-server-2012-01-16/)
Splitter:
CREATE FUNCTION [dbo].[Splitter]
(
#String NVARCHAR(4000),
#Delimiter NCHAR(1)
)
RETURNS TABLE
AS
RETURN
(
WITH Split(stpos,endpos)
AS(
SELECT 0 AS stpos, CHARINDEX(#Delimiter,#String) AS endpos
UNION ALL
SELECT endpos+1, CHARINDEX(#Delimiter,#String,endpos+1)
FROM Split
WHERE endpos > 0
)
SELECT 'Id' = ROW_NUMBER() OVER (ORDER BY (SELECT 1)),
'Data' = SUBSTRING(#String,stpos,COALESCE(NULLIF(endpos,0),LEN(#String)+1)-stpos)
FROM Split
)
GO
Reverse:
CREATE FUNCTION [dbo].[udf_ReverseSequenceOrder] (
#Input nvarchar(200)
,#Delimiter nvarchar(5)
)
RETURNS nvarchar(200)
AS
BEGIN
DECLARE #Output nvarchar(200)
WHILE LEN(#Input) > 0
BEGIN
IF CHARINDEX(#Delimiter, #Input) > 0
BEGIN
SET #Output = SUBSTRING(#Input,0,CHARINDEX(#Delimiter, #Input)) + #Delimiter + ISNULL(#Output,'')
SET #Input = SUBSTRING(#Input,CHARINDEX(#Delimiter, #Input)+1,LEN(#Input))
END
ELSE
BEGIN
SET #Output = #Input + #Delimiter + ISNULL(#Output,'')
SET #Input = ''
END
END
RETURN SUBSTRING(#Output,0,LEN(#Output))
END
Well, this is the xml based solution. For SQL Server 2008 and above.
DECLARE #url VARCHAR(100) = 'AB-19-CALL'
SELECT MyUrl FROM
(
SELECT CAST('<Url><Part>' + REPLACE(#url,'-','</Part><Part>') + '</Part></Url>' AS XML) AS my_Xml
) t1
CROSS APPLY
(
SELECT
my_Data.D.value('Part[3]','varchar(50)') + '-' +
my_Data.D.value('Part[1]','varchar(50)') + '-' +
my_Data.D.value('Part[2]','varchar(50)') AS MyUrl
FROM t1.my_Xml.nodes('/Url') as my_Data(D)
) t2
Result
MyUrl

I'm currently doing a data conversion project and need to strip all alphabetical characters from a string. Unfortunately I can't create or use a function as we don't own the source machine making the methods I've found from searching for previous posts unusable.
What would be the best way to do this in a select statement? Speed isn't too much of an issue as this will only be running over 30,000 records or so and is a once off statement.
You can do this in a single statement. You're not really creating a statement with 200+ REPLACEs are you?!
update tbl
set S = U.clean
from tbl
cross apply

select Substring(tbl.S,v.number,1)

from master..spt_values v
where v.type='P' and v.number between 1 and len(tbl.S)
and Substring(tbl.S,v.number,1) like '[0-9]'
order by v.number

RichardTheKiwi's script in a function for use in selects without cross apply,

GO
Thanks RichardTheKiwi +1
Well if you really can't use a function, I suppose you could do something like this:
SELECT REPLACE(REPLACE(REPLACE(LOWER(col),'a',''),'b',''),'c','')
FROM dbo.table...
Obviously it would be a lot uglier than that, since I only handled the first three letters, but it should give the idea.
