Migration File Format Reference (config v2)
Introduction
With config v2
, the Migrations files generated by the CLI are pure SQL
files.
Note
For config v1
, see Migration file format reference (config v1)
Migration filename format
Each migration file has the following format:
<version>_<name>.{up|down}.sql
A version
which is the Unix timestamp in nanoseconds when the file was
created is the first part. Followed by a name
which is either manually
added or auto-generated by the Console. The next part indicates what
step this is. If it is up
, it means that this is the forward step,
e.g. creating a table. The down
indicates that it is the corresponding
rollback step.
Migration file format
A migration SQL file can contain SQL statements which are executed on
the apply step of the migration. There can be an up
migration and a
down
migration file.
