securing mySQL table data

In my app I have a bunch of tables (maybe 30). One of the tables holds important info that includes the email addresses of employees. I'd like to secure this table. Should I be relying on a mySQL feature or should I be encrypting email addresses with CI before saving them to the mySQL table?

You can use MySQL owner rights to only allow yourself to access it for certain things

Like you said you could also encrypt the data.

What did you Try? What did you Get? What did you Expect?

Thanks. I will check out owner rights. I guess encrypting the data would be best but will make it really hard to debug
