Modify all tables in a database with a single command

Is there a single or a one line command to modify all tables within a database. I would like to issue this command in every table within a database:

ALTER TABLE `table_name` CONVERT TO CHARACTER SET utf8;

My objective is to modify the charset from latin1 to utf8 to all tables.

UPDATE: RDBMS is MySQL

No, there is no such command. But what you can do is write a quick query to generate the SQL for you like so:

USE INFORMATION_SCHEMA;
SELECT 
CONCAT("ALTER TABLE `", TABLE_SCHEMA,"`.`", TABLE_NAME, "` CONVERT TO CHARACTER SET UTF8;") 
AS MySQLCMD FROM TABLES 
WHERE TABLE_SCHEMA = "your_schema_goes_here";

Then you can run the output from this to do what you need.
