In Laravel, how does one modify the database table definition file to make it take effect?

For example, if you have a file 2016_06_21_200145_create_notes_table.php and modify the content, it will take effect if you manually rename the number 200145 and then execute phpartisanmigrate. For example, a file 2016_06_21_200145_create_notes_table.php, If I manually rename and modify the modified content 200145Execute this number again Php artisan migrateYes, but I don't know if this rule works.

Every time you execute php artisan migrate, the migrate file will be recorded in the migrations table in the database. changing the file name is equivalent to creating a new file.

If you want to modify the table after creating the table, you can use the 2016_06_21_222145_update_notes_table.php file to change the table structure,
You can modify the table structure multiple times by adding the year, month, and Day (2016_06_21_232145_update_notes_table20160621.php) after the table.

Note that the modified date and random number must be sequential.
