My brain isn't working right now. I have data such as 'HEYE-B Euro-IPA 69793' and 'HEYE-B RFE-IPA 70940'. I need to retrieve the middle value, such as 'Euro-IPA' or 'RFE-IPA'. How would that be coded to retrieve those values?

Forcing my brain to work resulted in the following. It's the best that I could manage. Seems to have done the trick.


CASE WHEN (CHARINDEX(' ',ColName)=0)
THEN 'Unknown'
ELSE SUBSTRING(ColName,CHARINDEX(' ',ColName)+1,
LEN(ColName) -
LEN(LEFT(ColName, CHARINDEX(' ',ColName))) -
LEN(RIGHT(ColName, CHARINDEX(' ',ColName) - 1)))
END AS [Middle_Value]

Using Jeff Moden's splitter you can do this...

DECLARE @spitme TABLE (Item varchar(40));
INSERT @spitme VALUES ('HEYE-B Euro-IPA 69793'), ('HEYE-B RFE-IPA 70940');

SELECT s.Item
FROM @spitme val
CROSS APPLY test.[dbo].[DelimitedSplit8K](val.Item,' ') s
WHERE ItemNumber = 2

Nasty fast set-based string manipulation functions:
For splitting strings try DelimitedSplit8K or DelimitedSplit8K_LEAD (SQL Server 2012+)
To split strings based on patterns try PatternSplitCM
Need to clean or transform a string? try NGrams, PatExclude8K, PatReplace8K, DigitsOnlyEE, or Translate8K

I cant stress enough the importance of switching from a sequential files mindset to set-based thinking. After you make the switch, you can spend your time tuning and optimizing your queries instead of maintaining lengthy, poor-performing code. -- Itzik Ben-Gan 2001

Another way:


DECLARE @spitme TABLE (Item varchar(40));
INSERT @spitme VALUES ('HEYE-B Euro-IPA 69793'), ('HEYE-B RFE-IPA 70940');

SELECT STUFF(STUFF(Item, 1, CHARINDEX(' ', Item), ''), CHARINDEX(' ', STUFF(Item, 1, CHARINDEX(' ', Item), '')), LEN(Item), '')
FROM @spitme




Please excuse me for having a bit of fun this morning. :-P


My mantra: No loops! No CURSORs! No RBAR! Hoo-uh!

My thought question: Have you ever been told that your query runs too fast?

My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.


Need to UNPIVOT? Why not CROSS APPLY VALUES instead?
Since random numbers are too important to be left to chance, let's generate some!
Learn to understand recursive CTEs by example.
Splitting strings based on patterns can be fast!

This maybe:

SELECT PARSENAME(REPLACE('HEYE-B RFE-IPA 70940',' ','.'),2);
Go
