Hello,

We recently upgraded from MySQL 4 to 5, and as a result the mysql.columns_priv table now has loads of '�'(black diamond with ? in it) in phpmyadmin, and '|' in MySQL Query Browser, after all the values, except 'Timestamp', and 'Colimn_prive' columns.

There are few with out this, but they were added after the upgrade. Also when using command line there are no extra characters, but using 'where Host = 'localhost' it only returns the new entries that do show the extra characters in phpmyadmin.

I have flushed, and repaired the table but this has not achieved anything.

what can we do to remove the '�'(black diamond with ? in it), ideally with out having to add all the permissions again!

Thanks

Welcome to WebmasterWorld, Tyskie.

You may need to run the mysql_upgrade command [dev.mysql.com] for your version of MySQL if you haven't yet. Read the whole page before beginning and be certain to do a backup first, just in case.
