There are some objects encoded as key:value strings and stored in a table, I'd like to increase sequence number of all objects, which is one field in the object.
For example:
ID Value
--------------------------
504 s:0;d:n;e:test;
506 s:1;d:y;e:branch;
507 s:2;d:y;e:;
I'd like to change them to:
ID Value
--------------------------
504 s:1;d:n;e:test;
506 s:2;d:y;e:branch;
507 s:3;d:y;e:;
Is there a simple way to do this?
Is there a simple way to do this?
No not really.
You can find the positions of s: and d: and then use that to extract the number inbetween, increase it by one and stuff it back into where it belongs.
declare #T table
(
ID int,
Value varchar(50)
);
insert into #T values
(504, 's:0;d:n;e:test;'),
(506, 's:1;d:y;e:branch;'),
(507, 's:2;d:y;e:;');
select T.ID,
stuff(T.Value, P.S, P.D - P.S - 1, S.Value) as NewValue
from #T as T
cross apply (values(charindex('s:', T.Value) + 2,
charindex('d:', T.Value))) as P(S, D)
cross apply (values(substring(T.Value, P.S, P.D - P.S - 1) + 1)) as S(Value)
A version where you find the ; after s: instead of d: as suggested by Eric in a comment.
select T.ID,
stuff(T.Value, S.Pos, SEnd.Pos - S.Pos, V.NewValue) as NewValue
from #T as T
cross apply (values(charindex('s:', T.Value) + 2)) as S(Pos)
cross apply (values(charindex(';', T.Value, S.Pos))) as SEnd(Pos)
cross apply (values(substring(T.Value, S.Pos, SEnd.Pos - S.Pos) + 1)) as V(NewValue)
DECLARE #val nvarchar(200)
SET #val = 's:1;d:y;e:branch;'
SELECT 's:' + CONVERT(nvarchar(100), CONVERT(INT, SUBSTRING(#val, charindex(':', #val) + 1, charindex(';', #val) - charindex(':', #val) -1)) + 1) + SUBSTRING(#val, charindex(':', #val),1000)
You can use what's in the SELECT's query in an UPDATE statement to change the table values
Using the split string functions from here:Split strings the right way – or the next best way
declare #string varchar(max)
set #string='504 s:0;d:n;e:test;'
;with cte as(select * from
[dbo].[SplitStrings_Numbers]
(#string,':'))
select b.item+1 from cte c
cross apply
(select * from [dbo].[SplitStrings_Numbers](c.item,';')) b
where isnumeric(b.item)=1
This accounts for empty or non-integer values; it will ignore them in the event they can't be incremented by one.
-- Build Test Data
IF OBJECT_ID('tempdb..#test') IS NOT NULL DROP TABLE #test
CREATE TABLE #test (ID INT, Value VARCHAR(100))
INSERT #test
VALUES
(504,'s:0;d:n;e:test;'),
(506,'s:1;d:y;e:branch;'),
(507,'s:2;d:y;e:;'),
(508,'s:;d:y;e:;'),
(509,'s:xyz;d:y;e:;');
-- Update S: values
WITH sVals AS
(
SELECT ID, Value, TRY_PARSE(SUBSTRING(Value,CHARINDEX('s:',Value)+2,CHARINDEX(';',Value,CHARINDEX('s:',Value))-(CHARINDEX('s:',Value)+2)) AS INT) AS sVal
FROM #test AS t
)
UPDATE s
SET Value = IIF(sVal IS NOT NULL, STUFF(Value,CHARINDEX('s:',Value)+2,CHARINDEX(';',Value,CHARINDEX('s:',Value))-(CHARINDEX('s:',Value)+2),sVal+1), Value)
FROM sVals AS s
-- Check the results
SELECT *
FROM #test
You can as the below:
DECLARE #val VARCHAR(100) = 's:12;d:n;e:test;'
SELECT REPLACE(#val, ':' + SUBSTRING(#val, 3, PATINDEX('%;d:%', #val) - 3) + ';', ':' + CAST(SUBSTRING(#val, 3, PATINDEX('%;d:%', #val) - 3)+ 1 AS VARCHAR(MAX)) + ';')
Result: s:13;d:n;e:test;

This is 2 examples of what the string currently look like:
6731-121-1
9552-3-1
This is what I want to pad them to look like
0006731-121-1
0009552-003-1
So I want them to be padded with 7 zeroes before the first '-' then 3 zeroes between the first and second '-'
What would be the best way to accomplish this in SQL SELECT statement.
SELECT RIGHT('0000000'
+ ISNULL(
LEFT(OE.exception_id, CHARINDEX('-', OE.exception_id)
- 1) ,
''
) ,7) + '-'
+ SUBSTRING(OE.exception_id, CHARINDEX('-', ( OE.exception_id )), 10) exception_id
ParseName() could be an option here
Example
Declare #YourTable Table ([YourCol] varchar(50))
Insert Into #YourTable Values
('6731-121-1')
,('9552-3-1')
Select *
,NewVal = right('0000000'+parsename(replace(YourCol,'-','.'),3),7)
+'-'
+right('000'+parsename(replace(YourCol,'-','.'),2),3)
+'-'
+parsename(replace(YourCol,'-','.'),1)
From #YourTable
Returns
YourCol NewVal
6731-121-1 0006731-121-1
9552-3-1 0009552-003-1
In situations with more than 3 periods
Example: '1.2.3.4.5'
Or any value is empty
3 examples: '1..3', '1.2.3.', '.2'
Parsename will return null for all values. You will need to split the column using a different method.
Here is an alternative to parsename:
DECLARE #table table(col varchar(100))
INSERT #table values('6731-121-1'),('9552-3-1')
SELECT
col,
REPLICATE('0', 8-x) + STUFF(col, x+1, 0,REPLICATE('0', 4 - (y-x))) newcol
FROM #table
CROSS APPLY
(SELECT CHARINDEX('-', col) x) x
CROSS APPLY
(SELECT CHARINDEX('-', col + '-', x+1) y) y
col newcol
6731-121-1 0006731-121-1
9552-3-1 0009552-003-1
i have string field like (1100,2014,4000) i want to separate comma and sum every number with each other for instance:
1100,2014,4000
1 1 0 0
2 0 1 4
4 0 0 0
result
#first =1+2+4=7
#second= 1+0+0=1
#third=0+1+0=1
#forth=0+4+0=4
This might help to get sum of values like this :
SELECT SUM(CAST(SUBSTRING(X.A, 1, 1) AS INT)) first,
SUM(CAST(SUBSTRING(X.A, 2, 1) AS INT)) second,
SUM(CAST(SUBSTRING(X.A, 3, 1) AS INT)) third,
SUM(CAST(SUBSTRING(X.A, 4, 1) AS INT)) fourth
FROM ( SELECT '1100' A
UNION
SELECT '2014' A
UNION
SELECT '4000' A
) X
Try this,
DECLARE #Table TABLE(Value VARCHAR(20))
INSERT INTO #Table VALUES('1100,2014,4000')
DECLARE #First INT, #Second INT, #Third INT, #Fourth INT
SELECT Split.a.value('.', 'VARCHAR(100)') AS Data
INTO #temp
FROM
(
SELECT CAST ('<M>' + REPLACE(Value, ',', '</M><M>') + '</M>' AS XML) AS Value
FROM #Table
) AS A CROSS APPLY Value.nodes ('/M') AS Split(a);
SELECT #First=SUM(Data/1000)
,#Second=SUM((Data%1000)/100)
,#Third=SUM((Data%100)/10)
,#Fourth=SUM((Data%10))
FROM #temp
SELECT #First, #Second, #Third, #Fourth
DROP TABLE #temp
Following Select statement with multiple SQL CTE expressions can be used with the help of a numbers table function and a SQL split string function for splitting numbers list using "," as seperator
For further splitting each number into its numerals, I preferred to use substring function
with cte as (
select
*
from NumbersList n,
dbo.NumbersTable(1,4,1) as nt
), splitted as (
select
list,
id,
i,
substring(val,i,1) val
from cte
cross apply dbo.Split(list,',') v
)
select
distinct
list,
i,
sum(cast(val as int)) over (partition by list, i) sumOf
from splitted
The output for following entries
insert into NumbersList select '1100,2014,4000'
insert into NumbersList select '1111,2222,3456'
is as follows
This, firstly, uses Jeff Moden's DelimitedSplit8K (as I don't know what version of SQl Server you're on). Secondly, your logic seems a little off. You say that the value for your variable #third is 0+4+0, however, that's the 4th characters of the ints. Also, this assumes that all integers are 4 characters long.
WITH VTE AS(
SELECT *
FROM (VALUES('1100,2014,4000')) v(DSn)) --This is your samnple data
SELECT SUM(CONVERT(int,SUBSTRING(RIGHT('0000' + DS.Item,4),N.I, 1))) AS [Sum]
FROM VTE
CROSS APPLY dbo.DelimitedSplit8K (VTE.DSn,',') DS
CROSS APPLY (VALUES (1),(2),(3),(4)) N(I)
GROUP BY N.I;
You can use this function for all item to row in a table.
you can create this function and try then
select * from dbo.string2table('1243,1234,2343',',')
CREATE FUNCTION [dbo].[string2table]
(
#string VARCHAR(MAX),
#delimiter CHAR(1)
)
RETURNS #output TABLE(
data VARCHAR(256)
)
BEGIN
DECLARE #start INT, #end INT
SELECT #start = 1, #end = CHARINDEX(#delimiter, #string)
WHILE #start < LEN(#string) + 1 BEGIN
IF #end = 0
SET #end = LEN(#string) + 1
INSERT INTO #output (data)
VALUES(SUBSTRING(#string, #start, #end - #start))
SET #start = #end + 1
SET #end = CHARINDEX(#delimiter, #string, #start)
END
RETURN
END
i have a table with a column have value seperated by semi colon.
the concern is value in the column are not fixed. it starts from 1 and end upto 80 semicolon sepaeration.
i am trying to put each individual value to seperate column
SQL SERVER 2008 code
DECLARE #Table TABLE(
Val VARCHAR(50)
)
INSERT INTO #Table (Val) SELECT '2Xcalcium; kidney' union all SELECT '3XMagnessium; liver' union all SELECT '2-ECG;3XSODIUM;DIALYSIS'
SELECT *,
CAST(LEFT(Val,CHARINDEX(';',Val)-1) AS VARCHAR) FirstValue,
CAST(RIGHT(Val,LEN(Val) - CHARINDEX(';',Val)) AS VARCHAR) SecondValue
FROM #Table
I tried the above code but this is limited to 2 semicolon only. please share your expertise.
Try it like this:
DECLARE #Table TABLE(
Val VARCHAR(50)
)
INSERT INTO #Table (Val) SELECT '2Xcalcium; kidney' union all SELECT '3XMagnessium; liver' union all SELECT '2-ECG;3XSODIUM;DIALYSIS';
;WITH Splitted AS
(
SELECT *
,CAST('<x>' + REPLACE(Val,';','</x><x>') + '</x>' AS XML) ValuesAsXML
FROM #Table
)
SELECT *
,ValuesAsXML.value('x[1]','varchar(max)') AS FirstCol
,ValuesAsXML.value('x[2]','varchar(max)') AS SecondCol
,ValuesAsXML.value('x[3]','varchar(max)') AS ThirdCol
,ValuesAsXML.value('x[4]','varchar(max)') AS FourthCol
,ValuesAsXML.value('x[5]','varchar(max)') AS FifthCol
FROM Splitted
The result
Val FirstCol SecondCol ThirdCol FourthCol FifthCol
2Xcalcium; kidney 2Xcalcium kidney NULL NULL NULL
3XMagnessium; liver 3XMagnessium liver NULL NULL NULL
2-ECG;3XSODIUM;DIALYSIS 2-ECG 3XSODIUM DIALYSIS NULL NULL
Most of the link provided extract the element into rows.
If you prefer to use your existing logic and extract the individual element into separate column, you can use multiple cascaded CROSS APPLY.
SELECT t.Val,
v1.V as V1,
v2.V as V2,
v3.V as V3
FROM #Table t
cross apply
(
select V = LEFT(t.Val, CHARINDEX(';', t.Val + ';') - 1),
Val = STUFF(t.Val, 1, CHARINDEX(';', t.Val + ';'), '')
) v1
cross apply
(
select V = LEFT(v1.Val, CHARINDEX(';', v1.Val + ';') - 1),
Val = STUFF(v1.Val, 1, CHARINDEX(';', v1.Val + ';'), '')
) v2
cross apply
(
select V = LEFT(v2.Val, CHARINDEX(';', v2.Val + ';') - 1),
Val = STUFF(v2.Val, 1, CHARINDEX(';', v2.Val + ';'), '')
) v3
From your question ,it seems that you have data in below format..This can be done easily with numbers table..
declare #string varchar(max)
set #string='s,t,a,c,k'
select substring(','+#string+',',n+1,charindex(',',','+#string+',',n+1)-n-1)
from
numbers
where n<=len(#string)
and substring(','+#string+',',n,1)=','
Output:
s
t
a
c
k

I am passing one string to store procedure : 1:20,2:30,4:50
It contains id and appropriate value for it.
how can I add value as shown in below table in database.
ID Value
1 20
2 30
4 50
I have already "stringSplit" function which works perfectly and gives out put in row value some think like this :
1:20
2:30
4:50
can anyone please help me to insert data into table with any solution.
i already try this solution
insert <table> (colname)
select y.item
from dbo.SplitString(#testString, ':') x
cross apply
dbo.SplitString(x.item, ',') y
but this will return duplicate value as more as id value.
my store procedure is
CREATE PROCEDURE [dbo].[temp_result_insert]
#dataString varchar(max)
AS
insert into tempTable(id,marks)
select x.Item,y.Item
from dbo.SplitStringVarcahr(#dataString, ':') x
cross apply
dbo.SplitStringVarcahr(x.Item,',') y
RETURN 0
As you already splitted into rows and you want insert into some table by splliting into two columns may be this works
CREATE TABLE #Test(ID INT,Val INT)
declare #t table (val varchar(50))
insert into #t (val)values ('1:20,2:30,4:50')
declare #str varchar(max)
;with cte as (
SELECT
Split.a.value('.', 'VARCHAR(100)') AS String
FROM (SELECT
CAST ('<M>' + REPLACE([val], ',', '</M><M>') + '</M>' AS XML) AS String
FROM #t) AS A CROSS APPLY String.nodes ('/M') AS Split(a))
INSERT INTO #Test
select SUBSTRING(String,0,CHARINDEX(':',String)),REVERSE(SUBSTRING(reverse(String),0,CHARINDEX(':',reverse(String)))) from cte
select * from #test
You can also try XML.nodes() and string functions to spit the data. Something like this
DECLARE #var VARCHAR(100) = '1:20,2:30,4:50'
DECLARE #xml xml = CONVERT(xml, '<r>' + REPLACE(#var,',','</r><r>') + '</r>')
SELECT LEFT(val,cindex - 1) c1,RIGHT(val,LEN(val) - cindex) c2
FROM
(
SELECT CHARINDEX(':',c.value('text()[1]','VARCHAR(100)')) cindex,c.value('text()[1]','VARCHAR(100)') val
FROM #xml.nodes('r') as t(c))c
Use substring and Charindex:
SELECT Substring(col, 0, Charindex(col, ':') - 1) AS id,
Substring(col, Charindex(col, ':') + 1, Len(col)-Charindex(col, ':')) AS value
FROM splittedtable
How can I get each value of a column that has a comma separator in her value ?
Example:
ID ColumnUnified
1 12,34,56,78
2 80,99,70,56
What I want is a query to get the number without comma. If possible, in collumns.
12 34 56 78
This will work for any number of values http://beyondrelational.com/modules/2/blogs/70/posts/10844/splitting-delimited-data-to-columns-set-based-approach.aspx
The solution Madhivanan's link refers to is very creative, but I had a slight problem with it on SQL Server 2012 related to the name of one of the columns (Start). I've modified the code in his answer to use StartPos instead of Start for the column name.
I was not familiar with the system procedure spt_values, but I found a very informative description of the procedure here on SO for those who are interested in exactly how this solution works.
Finally, here's the (slightly) revised code from Madhivana's answer:
CREATE TABLE #test(id int, data varchar(100))
INSERT INTO #test VALUES (1,'This,is,a,test,string')
INSERT INTO #test VALUES (2,'See,if,it,can,be,split,into,many,columns')
DECLARE #pivot varchar(8000)
DECLARE #select varchar(8000)
SELECT #pivot = COALESCE(#pivot + ',', '') + '[col'
+ CAST(number + 1 AS VARCHAR(10)) + ']'
FROM master..spt_values
WHERE type = 'p'
AND number <= ( SELECT MAX(LEN(data) - LEN(REPLACE(data, ',', '')))
FROM #test
)
SELECT #select = '
select p.*
from (
select
id,substring(data, StartPos+2, endPos-StartPos-2) as token,
''col''+cast(row_number() over(partition by id order by StartPos) as varchar(10)) as n
from (
select
id, data, n as StartPos, charindex('','',data,n+2) endPos
from (select number as n from master..spt_values where type=''p'') num
cross join
(
select
id, '','' + data +'','' as data
from
#test
) m
where n < len(data)-1
and substring(data,n+1,1) = '','') as data
) pvt
Pivot ( max(token)for n in (' + #pivot + '))p'
EXEC(#select)
DROP TABLE #test
