Robert Treat reported an error with find.best.tablespace.split.pl. In some cases it could die with ‘division by zero' error.
Problem was solved using patch from Robert, which simply treats “0" in number of rows fetched or written, as ‘0.001'.
Additionally, I added a simpler way to specify multiple schemas to use tables from.
Code is available in svn repository.
I was lately writing some program for a client of mine, which used UPC codes matching.
Since the codes are given in various ways, there was decision to pad the codes with leading zeros – up to 12 characters.
The code has been done, and worked like this:
# SELECT lpad('123456789', 12, '0'); lpad -------------- 000123456789 (1 ROW)
