Question

What is the difference between single quotes and double quotes in SQL?

Answer 1

A simple rule for us to remember what to use in which case:

• [S]ingle quotes are for [S]trings ; [D]ouble quotes are for [D]atabase identifiers;

In MySQL and MariaDB, the ` (backtick) symbol is the same as the " symbol. You can use " when your SQL_MODE has ANSI_QUOTES enabled.
