SPACE
The SPACE function returns the blank-delimited words in string with n pad characters between each word.
If you specify n, it must be a positive whole number or zero. If it is
0, all blanks are removed. Leading and trailing blanks are always removed. The
default for n is 1, and the default pad
character is a blank.
Examples
SPACE('abc def ') -> 'abc def'
SPACE(' abc def',3) -> 'abc def'
SPACE('abc def ',1) -> 'abc def'
SPACE('abc def ',0) -> 'abcdef'
SPACE('abc def ',2,'+') -> 'abc++def'
