MySQL: how to quote or escape field names?

Question

Recently I was given a MySQL DB that included a field named time-taken, which caused errors when used in a select because of the minus sign.

In this case I was able to rename the field, but for future reference how can field names be quoted or escaped in a MySQL query?

Answer 1

Put the field in backticks.

SELECT * from `table` WHERE `int` = 0
