Error when importing exported view with USE INDEX hint

[M393]

Describe the bug

CREATE VIEW statements are written to the exported sql before indexes, when the view uses USE INDEX (...) import fails.

To Reproduce

CREATE SCHEMA s;
USE `s`;

CREATE TABLE `t` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(45) DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `t_name` (`name`)
);
CREATE VIEW `v`  AS SELECT `t`.`id` AS `id`, `t`.`name` AS `name` FROM `t` USE INDEX (`t_name`) ;

Steps to reproduce the behavior:

1. Execute the sql above
2. Select the schema
3. Click on Export tab
4. Click on Export button
5. Re-create schema: DROP SCHEMA s; CREATE SCHEMA s; USE s;
6. Execute the exported script

Expected behavior

Should be able to execute exported sql without error.

Server configuration

• Database version: MySQL 5.7.38
• phpMyAdmin version: 5.2.1

Hi @M393
Thanks for reporting this parser bug!
/cc @Tithugues if you want to have a look, else no worries

[williamdes]

Can you provide a screenshot for this @M393?

I don't think it is a parser bug.

This can be resolved by exporting indexes before views.

See the exported file:
