Some excellent work

DECLARE @TestVar VARCHAR(16);

DECLARE @StartTime DATETIME;

PRINT 'Old Method Scalar Function'

SELECT @StartTime = GETDATE();

SELECT@TestVar = Utility.f_ProperCase(PT.String)

PRINT CAST(DATEDIFF(ms,@StartTime,GETDATE()) AS VARCHAR) + ' MilliSeconds';

PRINT 'Dohsan'

SELECT @StartTime = GETDATE();

Original Test strings were small (16 chars), the original function was only for 255 although a few of the functions presented have been able to handle far more. So upping it to nearer the 255 limit to see how they cope (so all functions can be run)

IF OBJECT_ID('tempdb..#ProperTest','U') IS NOT NULL

DROP TABLE #ProperTest;

SELECTREPLICATE(STUFF(STUFF(CHAR(ABS(CHECKSUM(NEWID()))%26+65)

+ CHAR(ABS(CHECKSUM(NEWID()))%26+65)

+ CHAR(ABS(CHECKSUM(NEWID()))%26+65),N%16+1,1,' '),N%3+1,1,' '),14) AS String

INTO #ProperTest

FROMdbo.GetNums(1,300000);

I ran some similar comparisons, but I had run them up to handle varchar(8000) and ran against a million-row test table with the strings filled to capacity. They were running pretty close to each other (with MM being the best at ~28 seconds), but I haven't tested everything with special characters or multiple trailing spaces. Dropping down to a max length of 255 definitely improved performance (dropping the best to ~22 seconds), but I hadn't completed testing last night before I needed to get some sleep. 😛

All in all, I think the work done on this thread has been excellent.

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.

I wasn't sure how you wanted to handle "Low-Budget' and "3D" but either can be handled in the opposite manner by adjusting the match pattern.

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.

This thread has been fun to watch, thanks folks! Here's an option I'm surprised nobody posted up:

CREATE FUNCTION [dbo].[IF_ProperWithREPLACE]

(

@inputstring VARCHAR(8000)

)

RETURNS TABLE WITH SCHEMABINDING

AS

RETURN

(

SELECT ProperisedString =

REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(

REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(

' '+@inputstring COLLATE Latin1_General_BIN,

' a',' A'),' b',' B'),' c',' C'),' d',' D'),' e',' E'),' f',' F'),' g',' G'),' h',' H'),' i',' I'),

' j',' J'),' k',' K'),' l',' L'),' m',' M'),' n',' N'),' o',' O'),' p',' P'),' q',' Q'),' r',' R'),

' s',' S'),' t',' T'),' u',' U'),' v',' V'),' w',' W'),' x',' X'),' y',' Y'),' z',' Z')

)

It's about 8x faster than any of the solutions posted so far, leaving some scope for dealing with weird stuff like accents.

I came back to this thread today because I was trying to proper case some stuff around here. I needed to exclude tokens that contain at least a single digit but all other tokens should be init caps.

I made a slight modification to Dwain's that worked well for my purposes.

CREATE FUNCTION [dbo].[ProperCaseWithNumbers]

(

@StrIn VARCHAR(255)

)

RETURNS TABLE WITH SCHEMABINDING

AS

RETURN

SELECT STUFF((

SELECT CASE

WHEN split.Item LIKE '%[0-9]%'

THEN ' ' + split.Item

ELSE ' ' + Upper(LEFT(split.Item, 1)) + Lower(Substring(split.Item, 2, 255))

END AS word

FROM dbo.Delimitedsplit8k(@StrIn, ' ') split

FOR XML PATH('')

,TYPE

).value('.', 'varchar(255)'), 1, 1, '') AS ProperCased

We have some data coming from the mainframe and it is all caps but I need to make this data more "user friendly". Here is an example of this one in action.

declare @MyVals table (SeriesName varchar(25))

insert @MyVals

select '9400 SERIES' union all

select '9760 SERIES' union all

select 'ADE360 SERIES' union all

select 'CUSTOM' union all

select 'M16360 SERIES' union all

select 'N1260 SERIES' union all

select 'N3160 SERIES' union all

select 'PA360 SERIES' union all

select 'S260 SERIES'

select *

from @MyVals v

cross apply dbo.ProperCaseWithNumbers(v.SeriesName)

I wonder if a CLR function would be worth considering here? .NET includes the System.Globalization.TextInfo.ToTitleCase() function which seems to do a pretty good job getting things properly capitalized. Not perfect but perhaps an extension method could handle the edge cases ?
