Split and Replace the string in SqlServer 2008? - sql-server

Question

I want to split string 'GPIN-KH2-COH-24042014-02' by '-' in sqlserver 2008 and want to save in separate variables. How can I achieve this? Please help me in this regard.
Now I am using below function and pass it ('GPIN-KH2-COH-24042014-02', '-')
Create FUNCTION [dbo].[fnSplit]
(
#strInputList NVARCHAR (MAX), -- List of Delimited Items
#strDelimiter NVARCHAR (11) = ',' -- Delimiter that Separates Items
)
RETURNS #tblList TABLE (strItem NVARCHAR(250))
BEGIN
DECLARE #strItem NVARCHAR(MAX)
WHILE CHARINDEX(#strDelimiter,#strInputList,0) <> 0
BEGIN
SELECT
#strItem = RTRIM(LTRIM( (SUBSTRING (#strInputList, 1, CHARINDEX (#strDelimiter, #strInputList, 0) -1)))),
#strInputList = RTRIM(LTRIM( (SUBSTRING (#strInputList, CHARINDEX (#strDelimiter, #strInputList, 0) + LEN (#strDelimiter), LEN (#strInputList)))))
IF LEN(#strItem) > 0
INSERT INTO #tblList SELECT #strItem
END
IF LEN(#strInputList) > 0
INSERT INTO #tblList SELECT #strInputList
RETURN
END
Result:
strItem
GPIN
KH2
COH
24042014
02
When I was delimeter and string it return result in that table format as shown above. But I want to get last two rows. How can I get this?

Answer 1

CRETAE function and pass your string and Delimiter as parameter
FUNCTION:
CREATE FUNCTION [dbo].[Split](#String varchar(8000), #Delimiter char(1))
returns #temptable TABLE (items varchar(8000))
as
begin
declare #idx int
declare #slice varchar(8000)
select #idx = 1
if len(#String)<1 or #String is null return
while #idx!= 0
begin
set #idx = charindex(#Delimiter,#String)
if #idx!=0
set #slice = left(#String,#idx - 1)
else
set #slice = #String
if(len(#slice)>0)
insert into #temptable(Items) values(#slice)
set #String = right(#String,len(#String) - #idx)
if len(#String) = 0 break
end
return
end
And then call the function and use the values as you want
DECLARE #A VARCHAR (100)= 'GPIN-KH2-COH-24042014-02'
SELECT items
INTO #STRINGS
FROM dbo.split(#A,'-')
select * from #STRINGS

Use this function, download from here
usage
SELECT DBO.fnString_DelimeterIndex(N'GPIN-KH2-COH-24042014-02','-',1)
SELECT DBO.fnString_DelimeterIndex(N'GPIN-KH2-COH-24042014-02','-',2)
SELECT DBO.fnString_DelimeterIndex(N'GPIN-KH2-COH-24042014-02','-',3)
function
ALTER FUNCTION [dbo].[fnString_DelimeterIndex]
(
#Text NVARCHAR(4000),
#Delimiter CHAR,
#Section SMALLINT
)
RETURNS NVARCHAR(4000)
AS
BEGIN
DECLARE #NextPos SMALLINT,
#LastPos SMALLINT,
#Found SMALLINT,
#REVERSE BIT
IF #Section < 0
SELECT #Text = REVERSE(#Text)--, #Section=1,#REVERSE=1
SELECT #NextPos = CHARINDEX(#Delimiter, #Text, 1),
#LastPos = 0,
#Found = 1
WHILE #NextPos > 0 AND ABS(#Section) <> #Found
SELECT #LastPos = #NextPos,
#NextPos = CHARINDEX(#Delimiter, #Text, #NextPos + 1),
#Found = #Found + 1
RETURN CASE
WHEN #Found <> ABS(#Section) OR #Section = 0 THEN NULL
--WHEN #REVERSE =1 THEN
WHEN #Section > 0 THEN SUBSTRING(#Text, #LastPos + 1, CASE WHEN #NextPos = 0 THEN DATALENGTH(#Text) - #LastPos ELSE #NextPos - #LastPos - 1 END)
ELSE REVERSE(SUBSTRING(#Text, #LastPos + 1, CASE WHEN #NextPos = 0 THEN DATALENGTH(#Text) - #LastPos ELSE #NextPos - #LastPos - 1 END))
END
END

Here is a fancy way of solving it:
You need a function to split it first:
create function [dbo].[f_specialsplit]
(
#param nvarchar(max),
#delimiter char(1)
)
returns #t table (val nvarchar(max), rn varchar(9))
as
begin
set #param += #delimiter
;with a as
(
select cast(1 as bigint) f, charindex(#delimiter, #param) t where #param is not null
union all
select t + 1, charindex(#delimiter, #param, t + 1)
from a
where charindex(#delimiter, #param, t + 1) > 0
)
insert #t
select substring(#param, f, t - f), row_number() over (order by (select 1)) from a
option (maxrecursion 0)
return
end
Trick is now to pivot the data into the variables:
DECLARE #str varchar(100) = 'GPIN-KH2-COH-24042014-02'
DECLARE #s1 varchar(100),#s2 varchar(100),#s3 varchar(100),#s4 varchar(100),#s5 varchar(100)
SELECT #s1=[1],#s2=[2],#s3=[3],#s4=[4],#s5=[5]
FROM f_specialsplit(#str,'-')
PIVOT
(min([val])
FOR rn
in([1],[2],[3],[4],[5])
)AS p
SELECT #s1,#s2,#s3,#s4,#s5
Result:
GPIN KH2 COH 24042014 02
