It's not clear what you mean by this comment, Martijn. SELECT...INTO
<variable> has to be a singleton.

FWIW, I think the reported problem has to do with the fact that the
stored procedure doesn't declare the variable as CHARACTER SET
OCTETS, so it is right-padding id with blanks instead of NULs (ascii
32 instead of ascii zero)..
