dbi_mysql_connect2.rb は何者ですか？

[sorah (Sorah Fukumori)]

• Status changed from Open to Feedback

ping?

[e_maekawa (eiichi maekawa)]

dbi_mysql_connect2.rbは、MySQLへアクセスする簡単なプログラムです。
コードは、以下です。

#!D:/Ruby/bin/ruby.exe -Ks

require "dbi"

begin
dbh = DBI.connect('DBI:Mysql:fbsys:'ｻｰﾊﾞ名', 'db名', 'PWD')
sth = dbh.prepare("SELECT * FROM テーブル名")
puts dbh
puts sth
sth.execute
puts 'count='+sth.rows.to_s

count = 0
sth.fetch { |row|
p row
count = count + 1
}
sth.finish
puts 'increment count='+count.to_s
#DB例外発生時の処理
rescue DBI::DatabaseError => e
p "An error occurred"
p "Error code: #{e.err}"
p "Error message: #{e.errstr}"
#切断漏れしないようにensureでdisconnectします。
ensure
dbh.disconnect if dbh
end

了

エラーメッセージで検索しただけで申し訳ないんですが、
新しいバージョンの mysql の libmysql.dll だと MySQL gem は動かない
ことがあるらしいです。

トレースからみてきっとこれだと思いましたので、ご確認ください。
直らなかったらすみません、reopen してください。
