我使用以下方法重命名数据库

使用mysqldump或任何数据库工具备份文件，如heidiSQL,mysql管理员等 在某些文本编辑器中打开备份(例如backupfile.sql)文件。 搜索并替换数据库名称并保存文件。

4.恢复已编辑的sql文件

当您在PHPMyAdmin中重命名数据库时，它会创建一个转储，然后删除并使用新名称重新创建数据库。

这是我所使用的:

$ mysqldump -u root -p olddb >~/olddb.sql
$ mysql -u root -p
mysql> create database newdb;
mysql> use newdb
mysql> source ~/olddb.sql
mysql> drop database olddb;

对于那些Mac用户，Sequel Pro在数据库菜单中有一个重命名数据库选项。 http://www.sequelpro.com/

TodoInTX的存储过程不太适合我。以下是我的尝试:

-- stored procedure rename_db: Rename a database my means of table copying.
-- Caveats: 
-- Will clobber any existing database with the same name as the 'new' database name.
-- ONLY copies tables; stored procedures and other database objects are not copied.

DROP PROCEDURE IF EXISTS rename_db;
CREATE PROCEDURE rename_db(IN old_db VARCHAR(100), IN new_db VARCHAR(100))
BEGIN
    DECLARE current_table VARCHAR(100);
    DECLARE done INT DEFAULT 0;
    DECLARE old_tables CURSOR FOR select table_name from information_schema.tables where table_schema = old_db;
    DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;

    SET @output = CONCAT('DROP SCHEMA IF EXISTS ', new_db, ';'); 
    PREPARE stmt FROM @output;
    EXECUTE stmt;

    SET @output = CONCAT('CREATE SCHEMA IF NOT EXISTS ', new_db, ';');
    PREPARE stmt FROM @output;
    EXECUTE stmt;

    OPEN old_tables;
    REPEAT
        FETCH old_tables INTO current_table;
        IF NOT done THEN
        SET @output = CONCAT('alter table ', old_db, '.', current_table, ' rename ', new_db, '.', current_table, ';');
        PREPARE stmt FROM @output;
        EXECUTE stmt;

        END IF;
    UNTIL done END REPEAT;

    CLOSE old_tables;

END//
delimiter ;

I posted this How do I change the database name using MySQL? today after days of head scratching and hair pulling. The solution is quite simple export a schema to a .sql file and open the file and change the database/schema name in the sql CREAT TABLE section at the top. There are three instances or more and may not be at the top of the page if multible schemas are saved to the file. It is posible to edit the entire database this way but I expect that in large databases it could be quite a pain following all instances of a table property or index.
