In this issue, the editor will bring you how to solve the mistakes in the database migration times in laravel. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Problem description

[Illuminate\ Database\ QueryException]

SQLSTATE [42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767bytes (SQL: alter table `users`add unique `users_email_ unique` (`email`))

[PDOException]

SQLSTATE [42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes

(1) laravel 5.4 or later changed the default database character set, and now utf8mb4 includes storage emojis support. If you run MySQL v5.7.7 or later, you don't need to do anything. (2) when you try to run the migrations command on some MariaDB or some older versions of MySQL, you may encounter the following error: Syntax error or access violation: 1071 Specified key was too long; max key length is 767bytes [the specified key is too long, the maximum key length is 767bytes, because the default string length of laravel is 767bytes, so you have to configure it manually. ]
