This is my Procure when i execute this Procedure whith input call TestExampl2_SP('a,m,n,x,y,z') i am getting notexistString ='x,y,z' but insetd of this i want result row wise i.e i have to split by comma
like this :
**value**
x
y
z
please suggest me how i will implement this .
You can follow below code to split string in sql.
CREATE FUNCTION SplitString
(
#Input NVARCHAR(MAX),
#Character CHAR(1)
)
RETURNS #Output TABLE (
Item NVARCHAR(1000)
)
AS
BEGIN
DECLARE #StartIndex INT, #EndIndex INT
SET #StartIndex = 1
IF SUBSTRING(#Input, LEN(#Input) - 1, LEN(#Input)) <> #Character
BEGIN
SET #Input = #Input + #Character
END
WHILE CHARINDEX(#Character, #Input) > 0
BEGIN
SET #EndIndex = CHARINDEX(#Character, #Input)
INSERT INTO #Output(Item)
SELECT SUBSTRING(#Input, #StartIndex, #EndIndex - 1)
SET #Input = SUBSTRING(#Input, #EndIndex + 1, LEN(#Input))
END
RETURN
END
And check using
SELECT Item FROM dbo.SplitString('Apple,Mango,Banana,Guava', ',')
I have varchar values like below
72,73,74
I try to split as a comma after that i want to convert to int above values.Than i want to match Id with my User Table.
CREATE FUNCTION Fn_MyFunction(#MyUserIdValues VARCHAR(100))
RETURNS VARCHAR(300) AS
BEGIN
DECLARE #Result VARCHAR(300) = ''
Select UserName From UserTable
Where MyUserIdValues=UserIdValues
RETURN #Result
#Result must be like below in one column
Joe,Michael,Ricky
Any help will be appreciated.
Thanks.
The classic way of doing this...
/*
create table Users
(
id int,
name nvarchar(max)
)
insert into Users
values
(72, 'Joe'),
(73, 'Michael'),
(74, 'Ricky'),
(75, 'Manny'),
(76, 'Bob')
*/
CREATE FUNCTION dbo.Fn_MyFunction(#IdValues VARCHAR(100))
RETURNS NVARCHAR(max) AS
BEGIN
DECLARE #Result NVARCHAR(max);
DECLARE #delimiter as nchar = ',';
WHILE LEN(#IdValues) <> 0
BEGIN
Declare #CurrentId int;
If CHARINDEX(#delimiter, #IdValues) = 0
begin
Set #CurrentId = cast(#IdValues as int);
Set #IdValues = ''
End
Else
begin
Set #CurrentId = cast(left(#IdValues, charindex(#delimiter, #IdValues) -1) as int)
Set #IdValues = Substring(#IdValues, charindex(#delimiter, #IdValues) +1, len(#IdValues))
End
select #Result = Isnull(#Result + ',', '') + Isnull((Select Name From Users Where Id=#CurrentId),'(unknown)')
END
RETURN #Result
END
GO
Select dbo.Fn_MyFunction('72,73,74')
--Joe,Michael,Ricky
Select dbo.Fn_MyFunction('72,0,74')
--Joe,(unknown),Ricky
Select dbo.Fn_MyFunction('72,73,72,74,74')
--Joe,Michael,Joe,Ricky,Ricky
GROUP_CONCAT and FIND_IN_SET might be a handy for you.
Try this:
SELECT GROUP_CONCAT(UserName)
FROM UserTable
WHERE FIND_IN_SET(MyUserIdValues,'72,73,74');
I had found solution for splitting string and inserting it in a table
GO
/****** Object: UserDefinedFunction [dbo].[Split] Script Date: 10/03/2013 11:45:16 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER FUNCTION [dbo].[Split] (
#InputString VARCHAR(8000),
#Delimiter VARCHAR(50)
)
RETURNS #Items TABLE (
Item int
)
AS
BEGIN
IF #Delimiter = ' '
BEGIN
SET #Delimiter = ','
SET #InputString = REPLACE(#InputString, ' ', #Delimiter)
END
IF (#Delimiter IS NULL OR #Delimiter = '')
SET #Delimiter = ','
DECLARE #Item VARCHAR(8000)
DECLARE #ItemList VARCHAR(8000)
DECLARE #DelimIndex INT
SET #ItemList = #InputString
SET #DelimIndex = CHARINDEX(#Delimiter, #ItemList, 0)
WHILE (#DelimIndex != 0)
BEGIN
SET #Item = SUBSTRING(#ItemList, 0, #DelimIndex)
INSERT INTO #Items VALUES (#Item)
-- Set #ItemList = #ItemList minus one less item
SET #ItemList = SUBSTRING(#ItemList, #DelimIndex+1, LEN(#ItemList)-#DelimIndex)
SET #DelimIndex = CHARINDEX(#Delimiter, #ItemList, 0)
END -- End WHILE
IF #Item IS NOT NULL -- At least one delimiter was encountered in #InputString
BEGIN
SET #Item = #ItemList
INSERT INTO #Items VALUES (#Item)
END
-- No delimiters were encountered in #InputString, so just return #InputString
ELSE INSERT INTO #Items VALUES (cast(#InputString as int))
RETURN
END -- End Function
Select UserName From UserTable where MyUserIdValues in(Select Item from Split('72,73,74',','))
//Call function Split using last query
Check this out, it will solve your problem and it simple and perfect method
Select Username from UserTable where MyUserIdValues IN ' + '('+ #Id +')'
My attempt (i think it's a little neater):
create function dbo.fn_UserNames(#ids varchar(max))
returns varchar(max) as
begin
set #ids = #ids + ','
declare #id table (Id int)
while(#ids != '') begin
insert into #id
select i
from (select substring(#ids, 1, charindex(',', #ids, 0) - 1) i) a
where i != ''
if #ids like '%,%'
set #ids = substring(#ids, charindex(',', #ids, 0) + 1,
len(#ids) - charindex(',', #ids, 0))
else
set #ids = ''
end
declare #ret varchar(max)
select #ret = isnull(#ret, '') + a.UserName + ','
from adhoc.UserTable a
join #id b on a.UserId = b.Id
return #ret
end
Hi you can try this one also.
CREATE FUNCTION [DBO].[FN_SPLIT] ( #STRSTRING VARCHAR(MAX))
RETURNS #NAME TABLE (NAME VARCHAR(MAX))
AS
BEGIN
DECLARE #USERID TABLE(ID INT)
DECLARE #USERS TABLE (ID INT , NAME VARCHAR(50))
INSERT INTO #USERS VALUES (72,'A'),(73,'B'),(74,'C')
;WITH STR_CTE(_START, _STOP) AS
(
SELECT 1, CHARINDEX(',' , #STRSTRING )
UNION ALL
SELECT CAST(_STOP + 1 AS INT), CHARINDEX(',' ,#STRSTRING , CAST((_STOP + 1) AS INT))
FROM
STR_CTE
WHERE _STOP > 0
)
INSERT INTO #USERID (ID)
SELECT
SUBSTRING(#STRSTRING , _START, CASE WHEN _STOP > 0 THEN _STOP -_START ELSE 4000 END) AS ID
FROM STR_CTE
DECLARE #STRNAME VARCHAR(MAX)
SELECT
#STRNAME = COALESCE(#STRNAME+',','') + U.NAME
FROM
#USERID UD
INNER JOIN
#USERS U ON UD.ID = U.ID
INSERT INTO #NAME
SELECT #STRNAME
RETURN;
END
I have a long string.I want to check throughout this string for consecutive 15 letters if there is no space i have to manually put a space in sql server. Can any one pls help??
For eg. my string is 'ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMNOPQRSTUVWXYZ'
then it should appear like 'ABCDEFGHIJKLMNOP QRSTUVWXYZABCDE FGHIJKLMNOPQRST UVWXYZ'
#dcp1986: I tried with your function as below.
SELECT dbo.UF_StringSplitter('HeloEveryonehru Howslyfgoingonn HaveaGoodDayGoodMorning')
But an unexpected split occured. I think your function must be modified as below for the correct result:
IF EXISTS(SELECT * FROM sysobjects WHERE ID = OBJECT_ID('UF_StringSplitter'))
DROP FUNCTION UF_StringSplitter
GO
CREATE FUNCTION UF_StringSplitter (
#psCSString VARCHAR(MAX)
)
RETURNS VARCHAR(MAX)
AS
BEGIN
DECLARE #sTemp VARCHAR(MAX)
DECLARE #tTemp VARCHAR(MAX)
SET #tTemp=''
WHILE LEN(#psCSString)>15
BEGIN
SET #sTemp = LEFT(LTRIM(#psCSString), 15)
SET #psCSString = LTRIM(SUBSTRING(#psCSString,16, LEN(#psCSString)))
IF #psCSString LIKE ' %'
SET #tTemp=#tTemp+#sTemp
ELSE
SET #tTemp=#tTemp+#sTemp+' '
END
SET #tTemp=#tTemp+#psCSString
RETURN #tTemp
END
You could use a function like this
IF EXISTS(SELECT * FROM sysobjects WHERE ID = OBJECT_ID('UF_StringSplitter'))
DROP FUNCTION UF_StringSplitter
GO
CREATE FUNCTION UF_StringSplitter
(
#psCSString VARCHAR(MAX)
)
RETURNS VARCHAR(MAX)
AS
BEGIN
DECLARE #sTemp VARCHAR(MAX)
DECLARE #tTemp VARCHAR(MAX)
SET #tTemp=''
WHILE LEN(#psCSString)>15
BEGIN
SET #sTemp = LEFT(#psCSString, 15)
SET #psCSString = SUBSTRING(#psCSString,16, LEN(#psCSString))
IF #psCSString LIKE ' %'
SET #tTemp=#tTemp+#sTemp
ELSE
SET #tTemp=#tTemp+#sTemp+' '
END
SET #tTemp=#tTemp+#psCSString
RETURN #tTemp
END
Go
Here i have hard coded the splitting value, and you can use the function
UPDATE mytable SET mycol=dbo.UF_StringSplitter(mycol)
I don't know how to do it on a single statement, but you can create a sql function something like this
create function AddStuffCharacterInLength (#original nvarchar(100), #take int, #stuff varchar(100))
returns nvarchar(200)
AS
BEGIN
declare #result nvarchar(200)
declare #len int
declare #skip int
set #len = len(#original)
set #result = ''
set #skip = (#take * -1) + 1
while #len > 0
begin
set #result = #result + substring(#original, #skip + #take, #take)
set #len = #len - #take
set #skip = #skip + #take
if #len > 0
set #result = #result + ' '
end
RETURN #result
END
And use it like this
select dbo.AddStuffCharacterInLength ('ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMNOPQRSTUVWXYZ',15, ' ')
And the output should be
----------------------------------------------------------------------------------------------------
ABCDEFGHIJKLMNO PQRSTUVWXYZABCD EFGHIJKLMNOPQRS TUVWXYZ
(1 row(s) affected)
I have a situation where I may need to pass a variable that could possibly hold a NULL value to a function, but through sp_executesql, so I will need to convert it to string value via string concatenation.
For Example:
declare #var1 varchar(10) = 'value'
declare #var2 varchar(10) = null
declare #sql nvarchar(2000)
.
.
set #sql = '
select dbo.fn_Scalar(''' + #var1 + ''', ''' + #var2 + ''' )
'
Function Definition:
Create Function [dbo].[fn_fn_Scalar]
(
#var1 varchar(10) ,
#var2 varchar(10) = null
) RETURNS float
AS BEGIN
Declare #ret float
Select #ret = sum(value)
from Table
where Field1 = #var1
and Field2 like isnull(#var2, '%')
return #ret
END
What would be the best approach to allow for fn_Scalar to be called via Dynamic and Static SQL statements and still allow for the second parameter to either be set to a value, NULL, or default.
You can pass parameters to sp_executesql function like so:
declare #var1 varchar(10) = 'value'
declare #var2 varchar(10) = null
Set #ParamDefinition = '#var1 varchar(10), #var2 varchar(10)'
Execute sp_Executesql 'select dbo.fn_Scalar(#var1,#var2)', #ParamDefinition, #var1, #var2
I have values like
string a,b;
a= "1,2,3,4";
b="admin";
I am passing a and b to SP and I want to save it in DB like
a b
1 admin
2 admin
3 admin
4 admin
How can I do this? Can someone give me some ideas on how to do it?
Thank you..
SQL doesn't have a concept of arrays, so this gets a bit interesting.
Pass a list as a string parameter:
DECLARE #INSTR as VARCHAR(MAX)
SET #INSTR = '2,3,177,'
DECLARE #SEPERATOR as VARCHAR(1)
DECLARE #SP INT
DECLARE #VALUE VARCHAR(1000)
SET #SEPERATOR = ','
WHILE PATINDEX('%' + #SEPERATOR + '%', #INSTR ) <> 0
BEGIN
SELECT #SP = PATINDEX('%' + #SEPERATOR + '%',#INSTR)
SELECT #VALUE = LEFT(#INSTR , #SP - 1)
SELECT #INSTR = STUFF(#INSTR, 1, #SP, '')
INSERT INTO myTable (a, b) VALUES (#VALUE, 'admin')
END
