Capitalize Function (Version 2.0) – T-SQL

Hi folks,

I’ve changed the t-sql code for Capitalize function, the previous capitalize function worked only if there is one space between words, but this version works even if there be more than one space between words.

with this version of Capitalize;

you can run the function like this:

select dbo.Capitalize(‘st    charles‘)

and this is a sample result:

St Charles

I used this code to replace multiple spaces with one space.

and the result is the Capitalize function that works on words or sentences and even if there are multiple spaces in the input.

CREATE FUNCTION [dbo].[Capitalize]

(

@text varchar(max)

)

RETURNS varchar(max)

AS

BEGIN

declare @outputtext varchar(max)

declare @spaceCount int

declare @counter int

declare @term varchar(max)

declare @index int

declare @spaceIndex int


set @outputtext=”

set @text=ltrim(rtrim(@text))

while charindex(‘  ‘,@text)>0

set @text=replace(@text,’  ‘,’ ‘)


set @spaceCount= len(@text)-len(replace(@text,’ ‘,”))

set @counter=0

set @index=1

while @counter<=@spaceCount

begin


if @index<>1 

begin

set @index=@index+1

end 


set @spaceIndex=charindex(‘ ‘,@text,@index)


if @spaceIndex=0

begin

set @spaceIndex=len(@text)+1

end

if @index<>1

begin

set @outputtext= @outputtext+’ ‘+ UPPER(substring(@text,@index,1))+LOWER(substring(@text,@index+1,(@spaceIndex-@index)-1))

end

else

begin

set @outputtext= @outputtext+ UPPER(substring(@text,@index,1))+LOWER(substring(@text,@index+1,(@spaceIndex-@index)-1))

end


set @counter=@counter+1

set @index=@spaceIndex


end


— Return the result of the function

RETURN @outputtext


END

you can run the function like this:

select dbo.Capitalize(‘st    charles’)

and this is a sample result:

St Charles
