Running in the command line
Migration library creates the ‘migrate’ script. It has the follow syntax:
Usage: command [options] [arguments] Options: -h, --help Display this help message -q, --quiet Do not output any message -V, --version Display this application version --ansi Force ANSI output --no-ansi Disable ANSI output -n, --no-interaction Do not ask any interactive question -v|vv|vvv, --verbose Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug Available commands: create Create the directory structure FROM a pre-existing database down Migrate down the database version. help Displays help for a command install Install or upgrade the migrate version in a existing database list Lists commands reset Create a fresh new database up Migrate Up the database version update Migrate Up or Down the database version based on the current database version and the migration scripts available version Get the current database version
The basic usage is:
vendor/bin/migrate <COMMAND> --path=<scripts> uri://connection
--path specify where the base.sql and migrate scripts are located.
If you omitted the
--path it will assume the current directory. You can also
MIGRATE_PATH environment variable with the base path
The uri://connection is the uri that represents the connection to the database. You can see here to know more about the connection string.
You can omit the uri parameter if you define it in the
MIGRATE_CONNECTION environment variable and the parameter path with
MIGRATE_PATH environment variable
export MIGRATE_CONNECTION=sqlite:///path/to/my.db export MIGRATE_PATH=/path/to/migrate_files
Create a empty directory structure with base.sql and migrations/up and migrations/down for migrations. This is useful for create from scratch a migration scheme.
migrate create /path/to/sql
If you already have a database but it is not controlled by the migration system you can use this method for install the required tables for migration.
migrate install mysql://server/database
Will apply all necessary migrations to keep your database updated.
migrate update mysql://server/database
Update command can choose if up or down your database depending on your current database version. You can also specify a version:
migrate update --up-to=34
Creates/replace a database with the “base.sql” and apply ALL migrations
migrate reset # reset the database and apply all migrations scripts. migrate reset --up-to=5 # reset the database and apply the migration from the # start up to the version 5. migrate reset --yes # reset the database without ask anything. Be careful!!
Note on reset: You can disable the reset command by setting the environment variable
MIGRATE_DISABLE_RESET to true:
