I have only one remark here. I think you should declare @OutputString as VARCHAR(4000) as well. Otherwise you will loose string content over 255 chars.

i have a question regarding this udf. English language specific the words like and, or, the are not marked as init cap, how can we handle it?

thanks in advance:

It’s a shame this forum doesn’t honor any type of formatting… the function looks quite nice when properly formatted. I’m trying to us non-breaking spaces but, if that doesn’t work, I’ll just post it flat…

I still have trouble with the apostrophe ‘S though.

It doesn’t seem to be recognizing the != ‘S’ because:

O’NEILL’S FURN GALLERY returns O’Neill’S Furn Gallery
and
ALEXANDRA’S returns Alexandra’S

Any ideas would be greatly appreciated because I have many more apostrophe S’s than O’Neil’s

Thanks

Is there any function which convert only KEYWORDS in upper case from stored procedure?

Mehul

declare @Foobar table(data varchar(1000))
insert into @Foobar
select 'this is only for testing' union all
select 'SEe if This workS well' union all
select 'TESTING DATA'
/*

select * from @Foobar

) AS data
from @Foobar

RETURN ISNULL(@OutputString,'')

If the input is null, it actually change it to empty string

So either modify that line to

RETURN @OutputString

or

change your SELECT to

select
isnull(nullif(dbo.udf_TitleCase(t.column),''),'Undefined') as AliasColumn
from
table as t
