[Ruby-DBI-devel] Broken result from Statement#to_a

[Shirai,Kaoru <sh...@ko...>]

Hi.

StatementHandle#each(#fetch) always gives the same Row object to block,
so we get broken result from StatementHandle#to_a.

Example:
  stat.execute
  stat.each { |row|
    p row
  }
  
  stat.execute
  p stat.to_a

Output:
  ["foo"]
  ["bar"]
  ["boo"]
  [["boo"], ["boo"], ["boo"]]
    => Should be [["foo"], ["bar"], ["boo"]]

We have to use StatementHandle#fetch_all to get correct result. Is there
any reason to keep StatementHandle#to_a returning broken array?

I suggest making StatementHandle#to_a to be an alias of
StatementHandle#fetch_all.
