How Can I Alter The Charset Of A Db Or Table?

[peterlaursen]

We do not yet provide such option from the GUI.

You can use SQL like 

“CREATE DATABASE DEFAULT CHARSET cp850”

“CREATE/ALTER TABLE tablename DEFAULT CHARSET cp850”

(and the charset for the databae and/or table will be different from the server default.

You can change the server defa

But two things you should note:

1)  This will only have effect on NEW databases and tables.

2)  After that when connecting with SQLyog choose 'cp850' for the connection and not '

default'

Many thanks peterlaursen.

But you were saying “You can change the server defa…”, is it how to change the server default charset?

Please explain me that.

[peterlaursen]

if you “ALTER TABLE … DEFAULT CHARSET ..” the byte sequence of what is stored is not changed,  And any character that is encoded differently in the two charsets will garble.

All charset setting only take effect with NEW data!

An example: those accented latin characters are stored using two bytes in UTF8, but only one

byte in LATIN*.  

If you have some data stored as UFT8 and “ALTER TABLE … DEFAULT CHARSET ..” every such character will become two (weird) characters!

You can export data to a .sql file, edit this file (and change the server default if you like) and import!
