split numbers based on special characters - sql-server

Question

I have a column as below:
numbers
---------
225/271-2001
5565/2233-123
1392551-6,X117
The rule is: separate the number based on dash(-) and slash(/).The comma should be removed(if present).The 'X' is considered as an extention will remain as is. I need to separate this as shown below.
I understand, both the patterns are different. However, I can consider this separate while writing the query.
I would like to split these numbers as below:
number1 | number2
---------------------------
2252001 2712001
5565123 2233123
1392551X117 1392556X117
I tried with below query:
SELECT
ID, number
, STUFF(
LEFT(number,CHARINDEX('-',number)-1),
LEN(LEFT(number,CHARINDEX('-',number)))-LEN(RIGHT(number,CHARINDEX('-',REVERSE(number))-1)),
LEN(RIGHT(number,CHARINDEX('-',REVERSE(number))-1)),
RIGHT(number,CHARINDEX('-',REVERSE(number))-1)
)
, SUBSTRING(number,CHARINDEX('/',number)+1,LEN(number)) AS [2ndnumber]
FROM [tablename]
WHERE numbers LIKE '[0-9][0-9][0-9]/[0-9][0-9][0-9]-[0-9][0-9][0-9][0-9]'
However, I'm not getting the result as expected. What am I doing wrong?

Answer 1

You have different rules for numbers with / and ,. So you have to divide your query. Here's one way:
declare #t table (numbers varchar(20))
insert into #t
values ('225/271-2001')
, ('5565/2233-123'), ('1392551-6,X117')
select
number1 = left(numbers, ci1 - 1) + right(numbers, len(numbers) - ci2)
, number2 = substring(numbers, ci1 + 1, ci2 - ci1 - 1) + right(numbers, len(numbers) - ci2)
from
#t
cross apply (select ci1 = charindex('/', numbers), ci2 = charindex('-', numbers)) a
where
charindex('/', numbers) > 0
union all
select
left(numbers, ci1 - 1) + right(numbers, len(numbers) - ci2)
, left(numbers, ci1 - 1 - (ci2 - ci1 - 1)) + substring(numbers, ci1 + 1, ci2 - ci1 - 1) + right(numbers, len(numbers) - ci2)
from
#t
cross apply (select ci1 = charindex('-', numbers), ci2 = charindex(',', numbers)) a
where
charindex(',', numbers) > 0
Output
number1 number2
----------------------------
2252001 2712001
5565123 2233123
1392551X117 1392556X117

Try below, it may help.
CREATE TABLE #temp(ID INT, number varchar(200))
INSERT INTO #temp VALUES(1,'225/271-2001')
INSERT INTO #temp VALUES(2,'5565/2233-123')
INSERT INTO #temp VALUES(3,'1392551-6,X117')
INSERT INTO #temp VALUES(4,'13925515-65,X119')
SELECT ID,number
,CASE -- When the pattern is '#/#-#'
WHEN CHARINDEX('/',number) > 0 AND CHARINDEX('-',number) > CHARINDEX('/',number)
THEN CAST(SUBSTRING(number,1,CHARINDEX('/',number)-1) AS VARCHAR(50))
+ CAST(SUBSTRING(number,CHARINDEX('-',number)+1,LEN(number)) AS VARCHAR(50))
-- When the pattern is '#-#,#'
WHEN CHARINDEX('-',number) > 0 AND CHARINDEX(',',number) > CHARINDEX('-',number)
THEN CAST(SUBSTRING(number,1,CHARINDEX('-',number)-1) AS VARCHAR(50))
+ CAST(SUBSTRING(number,CHARINDEX(',',number)+1,LEN(number)) AS VARCHAR(50))
ELSE number
END [1st number]
,CASE -- When the pattern is '#/#-#'
WHEN CHARINDEX('/',number) > 0 AND CHARINDEX('-',number) > 0
THEN CAST(REPLACE(SUBSTRING(number,CHARINDEX('/',number)+1,LEN(number)),'-','') AS VARCHAR(50))
-- When the pattern is '#-#,#'
WHEN CHARINDEX('-',number) > 0 AND CHARINDEX(',',number) > CHARINDEX('-',number)
THEN LEFT(CAST(SUBSTRING(number,1,CHARINDEX('-',number)-1) AS VARCHAR(50)),(CHARINDEX('-',number)-1)-LEN(RIGHT(LEFT(number,CHARINDEX(',',number)-1),CHARINDEX(',',number)-1-CHARINDEX('-',number))))
+ CAST(REPLACE(SUBSTRING(number,CHARINDEX('-',number)+1,LEN(number)),',','') AS VARCHAR(50))
ELSE number
END [2nd number]
FROM #temp
OUTPUT:
ID number 1st number 2nd number
----- ------------------- --------------- ---------------
1 225/271-2001 2252001 2712001
2 5565/2233-123 5565123 2233123
3 1392551-6,X117 1392551X117 1392556X117
4 13925515-65,X119 13925515X119 13925565X119

Answer 3

This query should give the expected result. Simple query using xml format.
CREATE TABLE #temp(ID INT, number varchar(200))
INSERT INTO #temp VALUES(1,'225/271-2001')
INSERT INTO #temp VALUES(2,'5565/2233-123')
INSERT INTO #temp VALUES(3,'1392551-6,X117')
;WITH Split_Names (ID,xmlname)
AS
(
SELECT ID,
xmlname= CASE WHEN CHARINDEX(',',number)=0
THEN CONVERT(xml,'<Names><name>'
+ REPLACE(REPLACE(REPLACE(number,'-', '<?name><name>'),'/', '</name><name>'),'?','/') + '</name></Names>')
WHEN CHARINDEX(',',number)>0
THEN CONVERT(xml,'<Names><name>'
+ REPLACE(REPLACE(REPLACE(
REPLACE(REPLACE(concat(LEFT(number,(CHARINDEX('-',number)-1)),CAST('/' as char(1)),LEFT(number,(CHARINDEX('-',number)-2)),SUBSTRING(number,CHARINDEX('-',number)+1,1),',',substring(number,CHARINDEX(',',number)+1,LEN(number))),'-','/'),',','-')
,'-', '<?name><name>'),'/', '</name><name>'),'?','/') + '</name></Names>')
END
FROM #temp
)
select xmlname.value('/Names[1]/name[1]','varchar(100)')+ xmlname.value('/Names[1]/name[3]','varchar(100)') NUMBER1,
xmlname.value('/Names[1]/name[2]','varchar(100)')+ xmlname.value('/Names[1]/name[3]','varchar(100)') NUMBER2
from Split_Names
drop table #temp
