Select Part of Column - sql

Question

I was wondering if anyone could help with a query to select part of a column.
The column 'criteriadata' contains data that would look like this:
CriteriaData
14 27 15 C
14 30 15 DD
14 38 15 Pass
14 33 15 Pass
How can I select just the data that appears after the number 15.
Many thanks.

Answer 1

SELECT RIGHT(CriteriaData,
LEN(CriteriaData) - CHARINDEX('15', CriteriaData, 1) - 2)
FROM TableName
WHERE CriteriaData LIKE '%15%';

Answer 2

declare #T table
(
CriteriaData varchar(20)
)
insert into #T values
('14 27 15 C'),
('14 30 15 DD'),
('14 38 15 Pass'),
('14 33 15 Pass')
select stuff(CriteriaData, 1, 3+charindex(' 15 ', CriteriaData), '')
from #T
Result:
---------
C
DD
Pass
Pass

Answer 3

If CriteriaCData always contains a pattern of 3 numbers of 2 numerics separated by a space then you always want to retrieve from 10th chars:
select SUBSTR(CriteriaCData, 10) from xxx
If you are under oracle min 10.g then use REGEXP_SUBSTR to retrieve the alpha pattern
SELECT upper(REGEXP_SUBSTR(CriteriaCData, '[a-zA-Z]*$')) FROM xxx

Answer 4

Since you seem to want everything from the ninth character onwards, you could use RIGHT and LEN
SELECT right([CriteriaData], len([CriteriaData]) - 9)
However, you'd be better off normalizing your data so it was already in a seperate column.

Answer 5

On oracle use LENGTH instead of LEN
SELECT substr(CriteriaData, 8, LENGTH(CriteriaData) - 9) from table

Answer 6

You should use substring with left functions
Have a look at this: How to extract this specific substring in SQL Server?
And this: http://msdn.microsoft.com/en-us/library/aa259342(v=sql.80).aspx

Answer 7

SELECT substring(criteriadata, 9, LEN(criteriadata)-8) from table
This assumes that the position of 15 is fixed.

Answer 8

Declare #x nvarchar(100) = '14 30 15 DD';
Select substring(#x, (select charindex('15',#x,1) + 2) ,len(#x));

Answer 9

I created a SQL function to split the criteria by the spaces and used the last remaining value after the last space.
create function dbo.getCriteria
(
#criteria varchar(500)
)
returns varchar(500)
begin
declare #space as int
select #space=charindex(' ', data) from mydata
while #space > 0
begin
set #criteria=substring(#criteria, #space + 1, len(#criteria))
select #space=charindex(' ', #criteria)
end
return #criteria
end
select dbo.getCriteria(data) from mydata

Answer 10

SELECT
RIGHT(CriteriaData, LEN(CriteriaData) - (CHARINDEX('15', CriteriaData, 1) - 2))
FROM
MyTable;

Answer 11

As I had trouble making prior answers work, I had to find my own and figure for future reference I'd leave it on Stack Overflow. My field has XML but it's an NVarchar field and should generalise just fine - if you have a clear criteria for left AND right surrounding strings.
It's not a complete match to this question but I hope it helps someone else who has huge strings in their columns and needs to snip out a string that varies in between two others!
WITH r
AS (
SELECT TOP 100 RIGHT(XMLData, LEN(XMLData)-CHARINDEX('<INVOICE_NO>', XMLData)-11) AS xmldata
FROM IncomingPartsInvoiceXML)
SELECT LEFT(xmldata, CHARINDEX('<\/INVOICE_NO>', XMLData)-1)
FROM r;
