Each character set has one or more collations, but each
collation is associated with one and only one character set.
Therefore, the following statement causes an error message
latin2_bin collation is not
legal with the
latin1 character set:
mysql> SELECT _latin1 'x' COLLATE latin2_bin; ERROR 1253 (42000): COLLATION 'latin2_bin' is not valid for CHARACTER SET 'latin1'
