I have a situation where a table row has a column that carries multiple values separated by commas. I want to split such rows into multiple rows each carrying one of the column values. here is an example
NAME IDS
ABC 123456, 234651, 345161
(6 byte vals w commas in between)
Need output as
ABC 123456
ABC 234651
ABC 345161
CREATE TABLE MULT_VALS (
NAME VARCHAR(100),
IDS VARCHAR(100)
)
INSERT INTO MULT_VALS VALUES ('ABC', '123456, 234651, 345161')
INSERT INTO MULT_VALS VALUES ('XYZ', '323457')
INSERT INTO MULT_VALS VALUES ('JHK', '245673, 342892')
INSERT INTO MULT_VALS VALUES ('LKM', '895688, 993722, 342822, 383535')
INSERT INTO MULT_VALS VALUES ('KKS', '895688')
Need the output in a table that is
NAME varchar(100)
ID CHAR(6)
Above will result in 11 rows.
Any help will be appreciated.
Thanks

Search this site for "DelimitedSplit8k" (Rev 06 is the current version AFAIK).

The following query will return the expected result

SELECT c.name, ID = LTRIM(split.Item)

FROM MULT_VALS c

CROSS APPLY dbo.DelimitedSplit8k(c.IDS,',') split

This is the 2K forum, Lutz. Probably not going to work here. 🙂

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Yes... there is a solution. Some very important high performance improvements have been made in the last couple of months to solutions to 2k5 and above... I need to try to echo those improvements in a 2k compatible "Tally Table" splitter for you. I'll try to get to that tonight. In the meantime, if you find a CSV splitter with a While Loop in it or any splitter (including one that uses a "Tally" or "Numbers" table) that concatenates a delimiter to the original string, I strongly recommend that you DON'T use it because of the hidden performance problems that will rear up and bite you in the future.

This is a one time thing and I have to finish today.. so after some thought process.. this what I have come up with....

alter table mult_vals add cnt smallint

--This tells me how many IDS are there

update mult_vals

set cnt = LEN(IDS) - LEN(REPLACE(IDS,',','')) + 1

--Then move diff sets to diff tables

select *

into #one

from mult_vals

where cnt = 1

select *

into #two

from mult_vals

where cnt = 2

select *

into #thr

from mult_vals

where cnt = 3

select *

into #for

from mult_vals

where cnt = 4

--Next union these together...

select * from #ONE

UNION

select name, substring(IDS, 1, 6) from #TWO

UNION

select name, substring(IDS, 9, 6) from #TWO

UNION

select name, substring(IDS, 1, 6) from #THR

UNION

select name, substring(IDS, 9, 6) from #THR

UNION

select name, substring(IDS, 17, 6) from #THR

UNION

select name, substring(IDS, 1, 6) from #FOR

UNION

select name, substring(IDS, 9, 6) from #FOR

UNION

select name, substring(IDS, 17, 6) from #FOR

UNION

select name, substring(IDS, 25, 6) from #FOR

Hi ,

I am having similar kind of requirement.

I have a table.

create table dbo.test(ID int,Price decimal(18,9), Qty decimal(18,9))

Insert into dbo.test values(1,5000,5000000)

Insert into dbo.test values(2,3000,50000000)

Insert into dbo.test values(3,100,50000)

I need the output in the below format

ID PRICE QTY

1 5000 5000000

2-1 30 5000000

2-2 30 5000000

2-3 30 5000000

2-4 30 5000000

2-5 30 5000000

2-6 30 5000000

2-7 30 5000000

2-8 30 5000000

2-9 30 5000000

2-10 30 5000000

3 100 50000

So the Qty limit is : 5,000000

First record is equal to the limit.So it can appear in the same format as stored in table.

In Second Record -Qty is 10 times greater than our limit.So all the columns are splitted as shown above

Third Row - It is within the limit we have set for Qty.So it can appear in the same format as stored in table.

Any help is appreciated.

Thanks

You should start your own threads instead of hijacking a number of other much older threads.
