What rules apply to naming a mysql column?

Question

In a MySQL table, naming a column, can I use

• spaces
• uppercase letters
• UTF8 characters

What other rules shall I follow?

( MySQL5 )

Answer 1

Yes, Yes, and Yes.

I like underscores between field names and no uppercase, but I don't want to start a flame war.

Another good reason to not use special characters in column names is you, or others are eventually going to have to type that over and over in your application. I'd stick to the standard english alphabet.

Good column names:

account_id
user_id
first_name

Bad column name:
