at 8:57 solomon 1171210 1 This may help you to understand stackoverflow.com/questions/160233/… –Imdad May 17 '12 at 9:04 @Imdad This link describes another error - (errno: 150) –Devart May 17 '12 at 9:17 Try this. Create new table (without foreign key constraint). copy the data to new table (using syntax INSERT INTO new_table SELECT * FROM old_table) Drop the old table –Imdad May 17 '12 at 9:22 Have you checked @Maksym Polshcha's answer?

Local Community Meetups Laravel.io Site and Community Forum Database migrate:reset erring when dropping foreign key I'm having an issue when rolling back a migration that drops foreign keys. I'm creating the foreign keys in their foreign key own migration file to avoid any issues with the tables not being present and the migration itself works fine. However, the reset provides the following SQL error. [Illuminate\Database\QueryException] SQLSTATE[HY000]: General error: 1025 Error on rename of drop foreign key [emailprotected]/authors_books' to [emailprotected]/#sql2 20a-f4' (errno: 152) (SQL: alter table `authors_books` drop foreign key author_id) Everything seems fine.
