xtra spaces between characters of a string value is a common problem and if you’re a developer then you must have faced the problem. On request of a blog reader here is a script from my query bank which I like to use to remove such extra spaces.
--Create a temp table for testing our query
CREATE TABLE #ExtraSpaces ( MyVal VARCHAR(8000))

SET MyVal = REPLACE(
SUBSTRING(MyVal, 1,
CHARINDEX(' ', MyVal, 1) - 1) + ' '

WHERE CHARINDEX(' ', MyVal, 1) > 0
