* + backtick (<kbd>`</kbd>) -- due to MySQL
* + double quote (<kbd>"</kbd>) -- due to Oracle
* + brackets (<kbd>[</kbd> or <kbd>]</kbd>) -- due to Access
*
* Delimited identifiers are known to generally work correctly under
* the following drivers:
* + mssql
* + mysql
* + mysqli
* + oci8
* + pgsql
* + sqlite
*
* InterBase doesn't seem to be able to use delimited identifiers
