Hi,

I am trying to import into SQL Server 2008 R2 a list of strings as follows:

=KET+N.207-13-F4001
=KET+DG014-13-F4011
=KET+RE002-36-MV009

I need to split the strings so they are inserted into separate fields. One of the substring statements is:

'SUBSTRING(xlCode; 15; 2) [if the second position is a number, and]
'SUBSTRING(xlCode; 15; 1) [if the second position is anything else]
AS GroupNo

My experience with T-SQL is just not enough to figure this one out. Can you tell me how the statement should be set up?

Thanks in advance for any help.

Maarten

First, welcome to SSC. To save you some grief - in the future I would suggest posting some DDL so that we can better understand exactly what you are trying to do. See the link at the bottom for more details.

You can go to this article for a copy of the PatternSplit function I am using (and a great read).

Because I am not sure exacly how you want to split your strings up I will give you a couple ideas to get started; see my comments in the code for more details....

IF OBJECT_ID('tempdb..#strings') IS NOT NULL DROP TABLE #strings;
CREATE TABLE #strings (string_id int primary key, string varchar(20));

INSERT INTO #strings
SELECT 1, 'KET+N.207-13-F4001' UNION ALL SELECT 2,'KET+DG014-13-F4011' UNION ALL SELECT 3,'KET+RE002-36-MV009';

SELECT string_id, item
FROM #strings s
CROSS APPLY dbo.PatternSplitCM(string,'%-%')
WHERE Matched=0
GO

--Lets say we want to split by '-' & '+'
SELECT string_id, item
FROM #strings
CROSS APPLY dbo.PatternSplitCM(string,'%[+-]%')
WHERE Matched=0

--Lets say we want to split by '-' & '+' & '.'
SELECT string_id, item
FROM #strings
CROSS APPLY dbo.PatternSplitCM(string,'%[+-.]%')
WHERE Matched=0

Thanks for your reply, Alan.B.

I posted the same topic under the forum 'SQL Server 2008 - General' and got the answer I was looking for.

Here's the topic link:

Thanks for your input.
