Collation, Unique vs Index


j.silver

Recommended Posts

I am creating a table using phpMyAdmin. I would appreciate if someone would explain:

  1. In the collation, I am selecting utf8_general_ci. Is this OK?
  2. For indexing, when should I use ''unique and when would I use 'index'?

It's OK if you want to use case-insensitive UTF-8.

Use unique if you want the database to enforce unique values in that column. Make it an index if it is a foreign key or is often used for searching, like with joins or the WHERE clause.
