I have an email column that stores a minimum of more than 10 emails in a row. Now, I want to write a query that puts each email on a separate line, e.g:
hay#line.com
u#y.com
live.gmail.com
How do write this?
If you mean rows of data... Any Parse/Split function will do if you don't have 2016. Otherwise the REPLACE() as JohnHC mentioned
Declare #YourTable table (ID int,Emails varchar(max))
Insert Into #YourTable values
(1,'hay#line.com,u#y.com,live.gmail.com')
Select A.ID
,EMail=B.RetVal
From #YourTable A
Cross Apply [dbo].[udf-Str-Parse](A.EMails,',') B
Returns
ID EMail
1 hay#line.com
1 u#y.com
1 live.gmail.com
Or Simply
Select * from [dbo].[udf-Str-Parse]('hay#line.com,u#y.com,live.gmail.com',',')
Returns
RetSeq RetVal
1 hay#line.com
2 u#y.com
3 live.gmail.com
The Function if Needed
CREATE FUNCTION [dbo].[udf-Str-Parse] (#String varchar(max),#Delimiter varchar(10))
Returns Table
As
Return (
Select RetSeq = Row_Number() over (Order By (Select null))
,RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>'+ Replace(#String,#Delimiter,'</x><x>')+'</x>' as xml).query('.')) as A
Cross Apply x.nodes('x') AS B(i)
);
--Select * from [dbo].[udf-Str-Parse]('Dog,Cat,House,Car',',')
--Select * from [dbo].[udf-Str-Parse]('John Cappelletti was here',' ')
Use Replace()
select replace(MyEmailField, '<CurrentDelimeter>', char(13)) as NewEmail
from MyTable

I did find some info on the site but I am unable to make it work correctly. I have a text field [User] that contains USER: John.Smith SessionId: {There is a space after User: and one after the name}
Everything I tried will either remove the first section or the last one, none remove both. Or will give me this message Invalid length parameter passed to the LEFT or SUBSTRING function
I want to have the name John.Smith extracted from that field.
If possible I do not want to declare any tables.
Thanks
Why not use replace()?
select replace(replace(col, 'USER: ', ''), ' SessionId:', '')
If open to a TVF
Example
Select A.ID
,B.*
From YourTable A
Cross Apply [dbo].[tvf-Str-Extract](SomeCol,'USER:','SessionId:') B
Returns
ID RetSeq RetVal
1 1 John.Smith
The Function if Interested
CREATE FUNCTION [dbo].[tvf-Str-Extract] (#String varchar(max),#Delim1 varchar(100),#Delim2 varchar(100))
Returns Table
As
Return (
Select RetSeq = row_number() over (order by RetSeq)
,RetVal = left(RetVal,charindex(#Delim2,RetVal)-1)
From (
Select RetSeq = row_number() over (order by 1/0)
,RetVal = ltrim(rtrim(B.i.value('(./text())[1]', 'varchar(max)')))
From ( values (convert(xml,'<x>' + replace((Select replace(#String,#Delim1,'§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>').query('.'))) as A(XMLData)
Cross Apply XMLData.nodes('x') AS B(i)
) C1
Where charindex(#Delim2,RetVal)>1
)
/*
Declare #String varchar(max) = 'Dear [[FirstName]] [[LastName]], ...'
Select * From [dbo].[tvf-Str-Extract] (#String,'[[',']]')
*/
I got SUBSTRING() to work:
SUBSTRING(USER, 7,(LEN(USER)-7)-(charindex('SessionId',USERID)))
Where:
7 = # of characters in "USERID:"
LEN(User)-7 counts the character length less the 7 from "USERID:"
charindex('SessionId',USERID) gives you the character location where "SessionId" starts
I need to output a string in between two strings. The problem is sometimes one of the two reference strings will be missing. If the first reference string is not missing and the second reference string is missing, I want to output from the first reference string to the end of the string. If the first reference string is missing, I want to output null or blank.
I saw a similar post but it included the reference strings. In my case, I do not want to include the reference strings.
SELECT SUBSTRING(#Text, CHARINDEX('1stRefStr', #Text)
, CHARINDEX('2ndRefStr',#text) - CHARINDEX('1stRefStr', #Text) + Len('2ndRefStr'))
Example:
Patient: A Date: 1/1/1 Message: Hi Message Sent To: B
1st string reference is "Message:"
2nd string reference is "Message Sent To:"
Expected Result:
Hi
If you don't mind a helper function.
Being a TVF, it is easy to incorporate into a CROSS APPLY if your data is in a table.
I modified a split/parse function to accept two non-like delimeters.
Example
Declare #Text varchar(max) = 'Patient: A Date: 1/1/1 Message: Hi Message Sent To: B'
Select *
From [dbo].[tvf-Str-Extract](#Text,'Message:','Message Sent') A
Returns
RetSeq RetVal
1 Hi
The Function
CREATE FUNCTION [dbo].[tvf-Str-Extract] (#String varchar(max),#Delim1 varchar(100),#Delim2 varchar(100))
Returns Table
As
Return (
Select RetSeq = row_number() over (order by RetSeq)
,RetVal = left(RetVal,charindex(#Delim2,RetVal)-1)
From (
Select RetSeq = row_number() over (order by 1/0)
,RetVal = ltrim(rtrim(B.i.value('(./text())[1]', 'varchar(max)')))
From ( values (convert(xml,'<x>' + replace((Select replace(#String,#Delim1,'§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>').query('.'))) as A(XMLData)
Cross Apply XMLData.nodes('x') AS B(i)
) C1
Where charindex(#Delim2,RetVal)>1
)
Update As A CROSS APPLY
Declare #YourTable table (ID int,SomeCol varchar(max))
Insert Into #YourTable values
(1,'Patient: A Date: 1/1/1 Message: Hi Message Sent To: B')
Select A.ID
,B.*
From #YourTable A
Cross Apply (
Select RetSeq = row_number() over (order by RetSeq)
,RetVal = left(RetVal,charindex('Message Sent',RetVal)-1)
From (
Select RetSeq = row_number() over (order by 1/0)
,RetVal = ltrim(rtrim(B.i.value('(./text())[1]', 'varchar(max)')))
From ( values (convert(xml,'<x>' + replace((Select replace(SomeCol,'Message:','§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>').query('.'))) as A(XMLData)
Cross Apply XMLData.nodes('x') AS B(i)
) C1
Where charindex('Message Sent',RetVal)>1
) B
Let's say I have 2 tables where both has column called Brand. The value is comma delimited so for example if one of the table has
ACER,ASUS,HP
AMD,NVIDIA,SONY
as value. Then the other table has
HP,GIGABYTE
MICROSOFT
SAMSUNG,PHILIPS
as values.
I want to compare these table to get all matched record, in my example ACER,ASUS,HP and HP,GIGABYTE match because both has HP. Right now I'm using loop to achieve this, I'm wondering if it's possible to do this in a single query syntax.
You are correct in wanting to step away from the loop.
Since you are on 2012, String_Split() is off the table. However, there are any number of split/parse TVF functions in-the-wild.
Example 1 - without a TVF
Declare #T1 table (Brand varchar(50))
Insert Into #T1 values
('ACER,ASUS,HP'),
('AMD,NVIDIA,SONY')
Declare #T2 table (Brand varchar(50))
Insert Into #T2 values
('HP,GIGABYTE'),
('MICROSOFT'),
('SAMSUNG,PHILIPS')
Select Distinct
T1_Brand = A.Brand
,T2_Brand = B.Brand
From (
Select Brand,B.*
From #T1
Cross Apply (
Select RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>' + replace(Brand,',','</x><x>')+'</x>' as xml)) as A
Cross Apply x.nodes('x') AS B(i)
) B
) A
Join (
Select Brand,B.*
From #T2
Cross Apply (
Select RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>' + replace(Brand,',','</x><x>')+'</x>' as xml)) as A
Cross Apply x.nodes('x') AS B(i)
) B
) B
on A.RetVal=B.RetVal
Example 2 - with a TVF
Select Distinct
T1_Brand = A.Brand
,T2_Brand = B.Brand
From (
Select Brand,B.*
From #T1
Cross Apply [dbo].[tvf-Str-Parse](Brand,',') B
) A
Join (
Select Brand,B.*
From #T2
Cross Apply [dbo].[tvf-Str-Parse](Brand,',') B
) B
on A.RetVal=B.RetVal
Both Would Return
T1_Brand T2_Brand
ACER,ASUS,HP HP,GIGABYTE

Had the same problem with comparing "," delimited strings
you can use "XML" to do that and compare the outputs and return the same/different value:
declare #TestInput nvarchar(255)
, #TestInput2 nvarchar(255)
set #TestInput = 'ACER,ASUS,HP'
set #TestInput2 = 'HP,GIGABYTE'
;WITH FirstStringSplit(S1) AS
(
SELECT CAST('<x>' + REPLACE(#TestInput,',','</x><x>') + '</x>' AS XML)
)
,SecondStringSplit(S2) AS
(
SELECT CAST('<x>' + REPLACE(#TestInput2,',','</x><x>') + '</x>' AS XML)
)
SELECT STUFF(
(
SELECT ',' + part1.value('.','nvarchar(max)')
FROM FirstStringSplit
CROSS APPLY S1.nodes('/x') AS A(part1)
WHERE part1.value('.','nvarchar(max)') IN(SELECT B.part2.value('.','nvarchar(max)')
FROM SecondStringSplit
CROSS APPLY S2.nodes('/x') AS B(part2)
)
FOR XML PATH('')
),1,1,'') as [Same Value]
Edit:
Changed 'Stuff' to 'XML'
I've inherited a database of user profile information which has a column for personal interests. Multiple interests are separated by a pipe (|). In a SQL query, how can I split a field with this value: 2|27|33|14|15
To look like this:
2
27
33
14
15
The exact syntax depends on which dbms you are using. Assuming you are using MSSQL this is the general syntax
STRING_SPLIT ( string , separator )
For example
DECLARE #string_to_be_split NVARCHAR(400) = '2|27|33|14|15'
SELECT value
FROM STRING_SPLIT(#string_to_be_split, '|')
WHERE RTRIM(value) <> '';
Edit - Could have sworn that I saw SQL Server
If not 2016, just about any Split/Parse Function will do.
Option 1 - With UDF
Declare #YourTable table (ID int,Interests varchar(250))
Insert Into #YourTable values
(1,'2|27|33|14|15')
Select A.ID
,B.*
From #YourTable A
Cross Apply [dbo].[udf-Str-Parse](A.Interests,'|') B
Option 2 - Without a UDF
Select A.ID
,B.*
From #YourTable A
Cross Apply (
Select RetSeq = Row_Number() over (Order By (Select null))
,RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>' + replace((Select replace(A.Interests,'|','§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml).query('.')) as X
Cross Apply x.nodes('x') AS B(i)
) B
Both Return
ID RetSeq RetVal
1 1 2
1 2 27
1 3 33
1 4 14
1 5 15
The UDF if Interested
CREATE FUNCTION [dbo].[udf-Str-Parse] (#String varchar(max),#Delimiter varchar(10))
Returns Table
As
Return (
Select RetSeq = Row_Number() over (Order By (Select null))
,RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
From (Select x = Cast('<x>' + replace((Select replace(#String,#Delimiter,'§§Split§§') as [*] For XML Path('')),'§§Split§§','</x><x>')+'</x>' as xml).query('.')) as X
Cross Apply x.nodes('x') AS B(i)
);

I'm trying to figure out how I can match and delete from on a multi delimited value.
For example
Table 1
Animal
Dog
Cat
Cow
Horse
Table 2
Animals
Leopard;fox;hen
Cat;fish
Cow;Horse;hen
I want to update the values in Table 2 (Animals) so the values in table 1 (Animal) are removed from the varchar value (in Table 2 (Animals)).
Example result:
Leopard;fox;hen
fish
hen
I'm not sure exactly how to approach this. I'm using SQL Server MGMT studio. Thanks in advance.
With the help of a Parse/Split Function and a Cross Apply.
I should note, the logic for the parse can easily be ported into the Cross Apply if you can't use (or want) a UDF.
Declare #Table1 table (Animal varchar(50))
Insert Into #Table1 values
('Dog'),
('Cat'),
('Cow'),
('Horse')
Declare #Table2 table (Animal varchar(50))
Insert Into #Table2 values
('Leopard;fox;hen'),
('Cat;fish'),
('Cow;Horse;hen')
;with cte as (
Select A.Animal
,B.*
From #Table2 A
Cross Apply [dbo].[udf-Str-Parse](A.Animal,';') B
Left Join #Table1 C on B.RetVal=C.Animal
Where C.Animal is null
)
Update #Table2 Set Animal=B.NewString
From #Table2 A
Join (
Select Distinct
Animal
,NewString = Stuff((Select ';' + RetVal From cte Where Animal=A.Animal For XML Path('')),1,1,'')
From cte A
) B on A.Animal = B.Animal
Returns
Animal NewString
Cat;fish fish
Cow;Horse;hen hen
Leopard;fox;hen Leopard;fox;hen
