I have a field column that contains values like
4
12,3
8,5,6,7
I'm going to write a SELECT statement, whose result would be:
4
12
8
How can I do it?
Try this
I'm hoping you are looking for this kind of solution.
DECLARE #table TABLE
(
ID INT IDENTITY(1,1),
Value NVARCHAR(MAX)
)
INSERT INTO #table VALUES('4'),('12,3'),('8,5,6,7')
select *,
IIF(CHARINDEX(',', [Value]) = 0, [Value],SUBSTRING([Value],1,(CHARINDEX(',',[Value])-1))) AS [OutPut]
from #table
Output
Try this
For SQL Server:
select if(charindex(',', numbers) = 0, numbers, LEFT(numbers, charindex(',', numbers) - 1))
from table;
For MySQL:
select if(instr(numbers, ',') = 0, numbers, LEFT(numbers, instr(numbers, ',') - 1))
from table;
Try this for SQL server
DECLARE #CSV_Split TABLE
(
Id INT IDENTITY(1,1),
CSVData NVARCHAR(MAX)
)
INSERT INTO #CSV_Split VALUES('4'),('12,3'),('8,5,6,7')
select *,LEFT(CSVData, CHARINDEX(',', CSVData + ',') - 1)
from #CSV_Split
The output is something like this:

I have the following query where I have a table which is storing from information with a delimiter
SQL version - Microsoft SQL Azure (RTM) - 12.0.2000.8
DECLARE #commanTable TABLE
(
CommaId NVARCHAR(MAX),
Name NVARCHAR(500)
)
DECLARE #commanTable1 TABLE
(
CommaId INT,
Name NVARCHAR(500)
)
INSERT INTO #commanTable VALUES ('2324205.3933251.7336404', 'Test1'),
('2324206.3933252.7336405', 'Test2')
INSERT INTO #commanTable1 (CommaId, Name)
SELECT value, Name
FROM #commanTable CROSS APPLY STRING_SPLIT(CommaId,'.');
SELECT * FROM #commanTable1
Getting the following results
Where I need the results to be
If you only interested in the first value, you don't need to use STRING_SPLIT(). You can simply use charindex() to find the first delimiter and use left() to extract it
SELECT *, left(CommaId, charindex('.', CommaId) - 1)
FROM #commanTable
Edit : if you always wanted the nth value, you can do a cascade charindex(). Provided that the n is not too huge. Else use the function that I provided in the comment.
SELECT *,
item1 = left(CommaId, p1.p - 1),
item2 = substring(CommaId, p1.p + 1, p2.p - p1.p - 1)
FROM #commanTable t
cross apply
(
select p = charindex('.', CommaId)
) p1
cross apply
(
select p = charindex('.', CommaId, p1.p + 1)
) p2
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
This is my String
Declare #qstr as varchar(max)='hireteammember.aspx?empemail=kuldeep#asselsolutions.com&empid=376&empname=kuldeep&adminname=TMA1&term=5&teamid=161&contactid=614¥1&WP=100¥5¥Months&Amt=500&DueDay=5&StrDt=12/31/2013&MemCatg=Employees&StrTm=21:05&PlnHrs=5&WrkDays=true¥true¥true¥true¥true¥false¥false'
I want to extract the values of empid,empname,adminname,term,teamid,contactid,WP,Months,Dueday,StrDt,MemCatgmStrTm,PlnHrs,WrkDays and assign them to new variables
I have used
select ( SUBSTRING(#qstr,CHARINDEX('=',#qstr)+1,CHARINDEX('&',#qstr)-CHARINDEX('=',#qstr)-1)))
but only getting the 'empemail' , for the next occurance of special char '&' , not able to get the values of further terms , if i am using '&' in spite of '=' .
Help me to split the whole string
How about using XML to split the values into rows, and then splitting them into columns.
Something like
Declare #qstr as varchar(max)='hireteammember.aspx?empemail=kuldeep#asselsolutions.com&empid=376&empname=kuldeep&adminname=TMA1&term=5&teamid=161&contactid=614¥1&WP=100¥5¥Months&Amt=500&DueDay=5&StrDt=12/31/2013&MemCatg=Employees&StrTm=21:05&PlnHrs=5&WrkDays=true¥true¥true¥true¥true¥false¥false'
DECLARe #str VARCHAR(MAX) = SUBSTRING(#qstr,CHARINDEX('?',#qstr,0) + 1, LEN(#qstr)-CHARINDEX('?',#qstr,0))
DECLARE #xml XML
SELECT #xml = CAST('<d>' + REPLACE(#str, '&', '</d><d>') + '</d>' AS XML)
;WITH Vals AS (
SELECT T.split.value('.', 'nvarchar(max)') AS data
FROM #xml.nodes('/d') T(split)
)
SELECT LEFT(data,CHARINDEX('=',data,0) - 1),
RIGHT(data,LEN(data) - CHARINDEX('=',data,0))
FROM Vals

I believe that this will do exactly what you are asking.
SQL FIDDLE DEMO
If the order of the values in the html string remains same i would suggest using the whole string name like
select ( SUBSTRING(#qstr,CHARINDEX('empemail=',#qstr)+1,CHARINDEX('&empid=',#qstr)-CHARINDEX('empemail=',#qstr)-1)))
If you are still looking for nth occurance then refer to this link
Declare #qstr as varchar(max)='hireteammember.aspx?empemail=kuldeep#asselsolutions.com&empid=376&empname=kuldeep&adminname=TMA1&term=5&teamid=161&contactid=614¥1&WP=100¥5¥Months&Amt=500&DueDay=5&StrDt=12/31/2013&MemCatg=Employees&StrTm=21:05&PlnHrs=5&WrkDays=true¥true¥true¥true¥true¥false¥false'
(select ( SUBSTRING(#qstr,CHARINDEX('&empname=',#qstr)+1,CHARINDEX('&adminname=',#qstr)-CHARINDEX('&empname=',#qstr)-1)))
(select ( SUBSTRING(#qstr,CHARINDEX('?empemail=',#qstr)+1,CHARINDEX('&empid=',#qstr)-CHARINDEX('?empemail=',#qstr)-1)))
like this i have splitted and updated The whole string. Thank you All for your answers, Your answers Helped me to solve this
I have data such as this:
Inventors column in my table
Hundley; Edward; Ana
Isler; Hunsberger
Hunsberger;Hundley
Names are separated by ;. I want to write a SQL query which sums up the count.
Eg. The result should be:
Hundley 2
Isler 1
Hunsberger 2
Edward 1
Ana 1
I could do a group by but this is not a simple group by as you can see. Any ideas/thoughts on how to get this output?
Edit: Changed results so it doesn't create any confusion that a row only contains 2 names.
You can take a look at this. I certainly do not recommend this way if you have lots of data, BUT you can do some modifications and use it and it works like a charm!
This is the new code for supporting unlimited splits:
Declare #Table Table (
Name Nvarchar(50)
);
Insert #Table (
Name
) Select 'Hundley; Edward; Anna'
Union Select 'Isler; Hunsberger'
Union Select 'Hunsberger; Hundley'
Union Select 'Anna'
;
With Result (
Part
, Remained
, [Index]
, Level
) As (
Select Case When CharIndex(';', Name, 1) = 0
Then Name
Else Left(Name, CharIndex(';', Name, 1) - 1)
End
, Right(Name, Len(Name) - CharIndex(';', Name, 1))
, CharIndex(';', Name, 1)
, 1
From #Table
Union All
Select LTrim(
Case When CharIndex(';', Remained, 1) = 0
Then Remained
Else Left(Remained, CharIndex(';', Remained, 1) - 1)
End
)
, Right(Remained, Len(Remained) - CharIndex(';', Remained, 1))
, CharIndex(';', Remained, 1)
, Level
+ 1
From Result
Where [Index] <> 0
) Select Part
, Count(*)
From Result
Group By Part

;with cte as
(
select 1 as Item, 1 as Start, CHARINDEX(';',inventors, 1) as Split, Inventors from YourInventorsTable
union all
select cte.Item+1, cte.Split+1, nullif(CHARINDEX(';',inventors, cte.Split+1),0), inventors as Split
from cte
where cte.Split<>0
)
select rTRIM(lTRIM(SUBSTRING(inventors, start,isnull(split,len(inventors)+1)-start))), count(*)
from cte
group by rTRIM(lTRIM(SUBSTRING(inventors, start,isnull(split,len(inventors)+1)-start)))
You can create a split function to split the col values
select splittedValues.items,count(splittedValues) from table1
cross apply dbo.split(col1,';') splittedValues
group by splittedValues.items
DEMO in Sql fiddle
first make one function who take your comma or any other operator(;) separated string into one table and by using that temp table, apply GROUP function on that table.
So you will get count for separate value.
"select d.number,count(*) from (select number from dbo.CommaseparedListToTable('Hundley;Edward;Ana;Isler;Hunsberger;Hunsberger;Hundley',';'))d
group by d.number"
declare #text nvarchar(255) = 'Edward; Hundley; AnaIsler; Hunsberger; Hunsberger; Hundley ';
declare #table table(id int identity,name varchar(50));
while #text like '%;%'
Begin
insert into #table (name)
select SUBSTRING(#text,1,charindex(';',#text)-1)
set #text = SUBSTRING(#text, charindex(';',#text)+1,LEN(#text))
end
insert into #table (name)
select #text
select name , count(name ) counts from #table group by name
Output
name count
AnaIsler 1
Hundley 2

I have a query like:
SELECT ...
FROM ...
WHERE .. AND SomeID = #someID
I'm inheriting this massive stored procedure that has some dynamic elements to it, so I need to get the value of someID from a column in another table i.e. perform a lookup.
How can I do that?
The other column looks like:
TypeValue
'SomeID=1232,OtherID=3383'
Some the column TypeValue is VARCHAR(1000), and it contains a comma seperated string of type & value pairs.
So I need to split on the , and then split on the = so somehow get:
SET #SomeID = SELECT TypeValue FROM MyTABLE WHERE ..
How can I do this?
(note, this is sql server 2000)
Assuming you're stuck with bad design, this doesn't require dynamic SQL:
USE tempdb;
GO
CREATE TABLE dbo.foo(ID INT, TypeValue VARCHAR(1000));
INSERT dbo.foo SELECT 1, 'SomeID=1232,OtherID=3383';
INSERT dbo.foo SELECT 2, 'Blat=prong,SomeID=1254';
INSERT dbo.foo SELECT 3, 'Foo=bar,x=23';
INSERT dbo.foo SELECT 4, 'SomeID=767';
INSERT dbo.foo SELECT 5, 'x=y,SomeID=126,OtherID=3383';
SELECT ID, Value = SUBSTRING(TypeValue,
CHARINDEX('SomeID', TypeValue) + 7,
COALESCE(NULLIF(CHARINDEX(',', SUBSTRING(TypeValue,
CHARINDEX('SomeID', TypeValue) + 8, 1000)), 0), 1000))
FROM dbo.foo
WHERE ',' + TypeValue LIKE '%,SomeID=%';
Results:
ID Value
--- -----
1 1232
2 1254
4 767
5 126
If you know which row you want:
DECLARE #ID INT, #Param VARCHAR(32);
SET #ID = 5;
SET #Param = 'SomeID';
DECLARE #val INT;
SELECT #val = SUBSTRING(TypeValue,
CHARINDEX(#Param, TypeValue) + LEN(#Param) + 1,
COALESCE(NULLIF(CHARINDEX(',', SUBSTRING(TypeValue,
CHARINDEX(#Param, TypeValue) + LEN(#Param) + 2, 1000)), 0), 1000))
FROM dbo.foo
WHERE ID = #ID
AND ',' + TypeValue LIKE '%,' + #Param + '=%';
PRINT #val;
Result:
126
This doesn't guard against someone putting a string into the SomeID value, of course, so may be safer to only convert to an INT if it is proven to be numeric. But you get the point.
