This question is completely different from similar ones. There is no foreign key in the SQL query. This is a silly error I see when I import the SQL file on remote server. This is the SQL code

CREATE TABLE `locations` (

  `id` int(10) UNSIGNED NOT NULL,

  `title` varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,

  `created_at` timestamp NULL DEFAULT NULL,

  `updated_at` timestamp NULL DEFAULT NULL

) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

As you see there is no foreign key, But when I run the following code, it is ok

CREATE TABLE `locations` (

  `id` int(10) UNSIGNED NOT NULL,

  `title` varchar(191) NOT NULL,

  `created_at` timestamp NULL DEFAULT NULL,

  `updated_at` timestamp NULL DEFAULT NULL

) ;

If I rename it to something else it is OK too.

CREATE TABLE `locationssss` (

  `id` int(10) UNSIGNED NOT NULL,

  `title` varchar(191) COLLATE utf8mb4_unicode_ci NOT NULL,

  `created_at` timestamp NULL DEFAULT NULL,

  `updated_at` timestamp NULL DEFAULT NULL

) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

what is wrong?

Do you have more tables within your database? If so, is there a table that does contain a foreign key connected with the locations table?

Do you have more tables within your database? If so, is there a table that does contain a foreign key connected with the locations table?
