SQL method to replace repeating blanks with single blanks

Question

Is there a more elegant way of doing this. I want to replace repeating blanks with single blanks....

   declare @i int

    set @i=0
    while @i <= 20
           


        

Answer 1

Lets say, your Data like this

Table name : userdata Field: id, comment, status, 

 id,  "I love -- -- - -spaces  -- -    my INDIA" , "Active" 

 id,  "I love -- -- - -spaces  -- -    my INDIA" , "Active" 

 id,  "I love -- -- - -spaces  -- -    my INDIA" , "Active" 

 id,  "I love -- -- - -spaces  -- -    my INDIA" , "Active" 

So just do like this

update userdata set comment=REPLACE(REPLACE(comment," ","-SPACEHERE-"),"-SPACEHERE"," ");

I didn't tested , but i think this will work.
