Split data from colon into new column - sql

Question

I have got a scenario where I want to split my data from colon into new column.
E.g YR:136;YR:50;JN:275;YM:138;IN:477;WO:150;G1:10;F2:10.
What I am looking for is this:
YR 136
YR 50
JN 275
YM 138
Can anybody tell me how to achieve this? Any help would be much appreciated.

Answer 1

for SQL 2016 and later you can use STRING_SPLIT. If not, search for CSV Spliter
declare #str varchar(100) = 'YR:136;YR:50;JN:275;YM:138;IN:477;WO:150;G1:10;F2:10'
select parsename(replace(value, ':', '.'), 2),
parsename(replace(value, ':', '.'), 1)
from string_split(#str, ';')

Answer 2

Hope the string will in the specified format every time. What I did was, first copied the same string to a new variable and added an extra ; to the end. Then used a WHILE loop to split each part before each ;. Then used LEFT and RIGHT function to take the parts before and after : from the splitted part. And inserted those values to a table variable #t.
Code
declare #str as varchar(max) ='YR:136;YR:50;JN:275;YM:138;IN:477;WO:150;G1:10;F2:10';
declare #rows as int;
set #rows = len(#str) - len(replace(#str, ';',''));
declare #t as table([col1] varchar(100), [col2] int);
declare #i as int;
set #i = 0;
declare #str2 as varchar(max);
set #str2 = #str + ';';
while(#i <= #rows)
begin
declare #col as varchar(100);
set #col = left(#str2, charindex(';', #str2, 1) - 1);
set #str2 = right(#str2, len(#str2) - charindex(';', #str2, 1));
insert into #t([col1], [col2])
select
left(#col, charindex(':', #col, 1) - 1),
right(#col, charindex(':', reverse(#col), 1) - 1);
set #i += 1;
end
select * from #t;

First CREATE the function:
CREATE FUNCTION dbo.fnSplit(
#sInputList VARCHAR(8000) -- List of delimited items
, #sDelimiter VARCHAR(8000) = ',' -- delimiter that separates items
) RETURNS #List TABLE (item VARCHAR(8000))
BEGIN
DECLARE #sItem VARCHAR(8000)
WHILE CHARINDEX(#sDelimiter,#sInputList,0) <> 0
BEGIN
SELECT
#sItem=RTRIM(LTRIM(SUBSTRING(#sInputList,1,CHARINDEX(#sDelimiter,#sInputList,0)-1))),
#sInputList=RTRIM(LTRIM(SUBSTRING(#sInputList,CHARINDEX(#sDelimiter,#sInputList,0)+LEN(#sDelimiter),LEN(#sInputList))))
IF LEN(#sItem) > 0
INSERT INTO #List SELECT #sItem
END
IF LEN(#sInputList) > 0
INSERT INTO #List SELECT #sInputList -- Put the last item in
RETURN
END
GO
Then try this:
DECLARE #X VARCHAR(100), #Val VARCHAR(250) = 'YR:136;YR:50;JN:275;YM:138;IN:477;WO:150;G1:10;F2:10'
SELECT LEFT(value,CHARINDEX(':',value) - 1)A
,RIGHT(value,CHARINDEX(':',REVERSE(value)) - 1)B
FROM dbo.fn_Split(#Val,';')
Output:
A B
YR 136
YR 50
JN 275
YM 138
IN 477
WO 150
G1 10
F2 10

Answer 4

In SQL Server you can do that using STRING_SPLIT.
For more information read the documentation:

Answer 5

--FOR SQL SERVER 2016+
DECLARE #str VARCHAR(100) = 'YR:136;YR:50;JN:275;YM:138;IN:477;WO:150;G1:10;F2:10'
SELECT SUBSTRING(value,0,CHARINDEX(':',value,0)) Id
, SUBSTRING(value,CHARINDEX(':',value,0)+1,100) Vals
FROM STRING_SPLIT(#str, ';')
--FOR Older SQL SERVER
DECLARE #x AS XML=''
SET #x = CAST('<A>'+ REPLACE(#str,';','</A><A>')+ '</A>' AS XML)
SELECT SUBSTRING(t.value('.', 'VARCHAR(MAX)') ,0,CHARINDEX(':',t.value('.', 'VARCHAR(MAX)') ,0)) Id
, SUBSTRING(t.value('.', 'VARCHAR(MAX)') ,CHARINDEX(':',t.value('.', 'VARCHAR(MAX)') ,0)+1,100) Vals
FROM #x.nodes('/A') AS x(t)

Answer 6

Try this below function
CREATE FUNCTION [dbo].[udf_GetUnsplitGivenData]
(
#string nvarchar(max)
)
RETURNS #OutTable TABLE
(
COl1 nvarchar(max),
COl2 nvarchar(max)
)
AS
BEGIN
DECLARE #Temp AS TABLE
(
DATA nvarchar(max)
)
INSERT INTO #Temp
SELECT #string
INSERT INTO #OutTable(COl1,COl2)
SELECT SUBSTRING(Data,1,CHARINDEX(':',Data )-1) AS COl1,
SUBSTRING(Data,CHARINDEX(':',Data )+1,LEN(Data)) AS COl2
FROM
(
SELECT Split.a.value('.','nvarchar(100)') AS Data
FROM
(
SELECT
CAST( '<S>'+REPLACE(Data,';','</S><S>')+'</S>' AS XML ) AS Data
FROM #Temp
) AS A
CROSS APPLY data.nodes('S') AS Split(a)
)dt
RETURN
END
SELECT * FROM [dbo].[udf_GetUnsplitGivenData] (
'YR:136;YR:50;JN:275;YM:138;IN:477;WO:150;G1:10;F2:10')
GO
Result
COl1 COl2
