NetBeansのチュートリアルに沿って、初期プロジェクトを作成したが、Databaseの作成に失敗する。

■なぜか、データベースが作成できない。

mysql> create database rubyweblog_development;
ERROR 1007 (HY000): Can’t create database ‘rubyweblog_development’; database exists

■どうやら、すでに同名のデータベースがある模様。（アンインストールに失敗していた？）
mysql> show databases;
+————————+
| Database |
+————————+
| information_schema |
| depot_development |
| mysql |
| rubyweblog_development |
| test |
+————————+
5 rows in set (0.23 sec)

■不要なデータベースを削除
mysql> drop database depot_development;
Query OK, 2 rows affected (0.33 sec)

mysql> drop database rubyweblog_development;
Query OK, 0 rows affected (0.00 sec)

mysql> drop database test;
Query OK, 0 rows affected (0.02 sec)

mysql> quit;
Bye

■無事作成できた。
