MySQL如何更改数据库名字

Create database NewDatabaseName;

SET @oldSchemaName = 'OldDatanaseName';
SET @newSchemaName = 'NewDatabaseName';

SET SESSION group_concat_max_len = 4294967295;

SELECT CONCAT('RENAME TABLE ', GROUP_CONCAT(mySchema.table_schema,'.`',table_name, '` TO ',@newSchemaName,'.`',table_name,'` \n'),';') AS Statement 
FROM information_schema.TABLES AS mySchema
WHERE mySchema.table_schema LIKE @oldSchemaName
GROUP BY mySchema.table_schema
;

运行以上返回结果中的SQL.

例如：

RENAME TABLE OldDatanaseName.`table1` TO NewDatabaseName.`table1` 
,OldDatanaseName.`table2` TO NewDatabaseName.`table2` 
,OldDatanaseName.`table3` TO NewDatabaseName.`table3` ;

最后将旧的数据库中自定义的存储过程在新的数据库中运行一次就可以了.
