I'd characterize Bruno's solution (chr(var1 + 48) ) as low-tech. It's the STRING function that's high tech.
The CHR solution only works, of course, under unstated assumptions about the contents of var1 (integers from 0 to 9) and language (single byte ASCII). But since it's likely to cause future problems, it's probably a good choice in this time of high unemployment in the IT sector.
