Removing spaces between words in sql

I guess there is no built in functions to do this but I have a function that replaces anything that is not A-Z with a space and returns @.data. What I additionally need the function to do is scrunch up @.data (remove all blanks betwwen each word so that 'I ran very fast' would be 'Iranveryfast').

What I need help in doing is the "Scrunch" part. Is there a way I could move the @.Data to something like @.DataHold and inspect each character, if it is not a blank, move that character back to @.Data?
This was pretty easy for me to do in C# with a while loop, but I do not know how to get it done in SQL Server 2005.

Thanks for any help!

Use the replace function.

replace( @.Data, ' ', '' )

For example,

DECLARE @.Data varchar(1000)
SET @.Data = 'I ran very fast'

SELECT replace( @.Data, ' ', '' )

Iranveryfast
