I work with the dynamic database I have a lot of databases and I wanna testing with hosting that free now I have found (Heroku) but when I use the command of laravel to create more database I got message say ( SQLSTATE[42501]: Insufficient privilege: 7 ERROR: permission denied to create database ) is possible or not if I wanna push my database to Heroku with data and I don't want to migrate it?
As the error message states you don't have the correct privileges to create a database.
If you want to move the data from one database to another you need to export it.
Not knowing what RDBMS you are using I can't point you to any guide on how to do that.
If it's just the database structure I recommend using Laravel migrations. If it's just a few tables with a few records in each that has default values use seeders for those.
@nithapple Heroku isn’t a “traditional” hosting platform. You have to “attach” databases to your application as add-ons; you can’t just create databases on demand from your application.
