Mysql - Cannot add foreign key constraint, there is no forign key in SQL query
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 thelocations
table?
