Escapes an alias name string.

Force all alias names to be strictly alphanumeric-plus-underscore. In contrast to DatabaseConnection::escapeField() / DatabaseConnection::escapeTable(), this doesn't allow the period (".") because that is not allowed in aliases.

Parameters

string $field: An unsanitized alias name.

Return value

string The sanitized alias name.

Overrides Connection::escapeAlias
