When running use dbname; in MySQL admin, I will get this message:

Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

But I still not clear about how to use -A?

The -A (or equivalently --no-auto-rehash) is to be added as an option to mysql when starting it from a command line, e.g.:

mysql -p -u myusername -A

Are you running mysql from a shell prompt, or through some web admin interface?
