Обсуждение: Standard SQL commands - are they in 6.5?

The following doesn't work in 6.xxx. Will it work  in 6.5????

............................
A standard SQL command to do this would be

ALTER TABLE tablename MODIFY existingColumnName CHAR( 24 );

This is an useful command, although it isn't an SQL standard command.
