Resetting autoincrement and truncate with cascade

Does knex provide any abstracted way of resetting autoincrement for a table? From what I can tell it can only be done using knex.raw() which makes it dependent on the dialect used.

A .resetIncrements() call would be nice so that it can be chained with .del() as knex('table_name').del().resetIncrements() which effectively resets a table to the state it was in when migrations were run.

For other Postgres users looking for a solution to this, I’ve found that this works well:

await knex.raw('TRUNCATE TABLE my_table RESTART IDENTITY CASCADE')

thanks @ais-one, you lead me to good path. I would just want to add, your sintax is database specific, and to another guy reading this, @ais-one solution might not work for you, dependint what db you are using.

To reset id in Postgres you need to specify <YOUTtableNAME_id_seq> It looks like this, usually do it after I delete all the tables.

await knex.raw('ALTER SEQUENCE requests_id_seq RESTART WITH 1')

await knex.raw('ALTER SEQUENCE profiles_id_seq RESTART WITH 1')

await knex.raw('ALTER SEQUENCE accounts_id_seq RESTART WITH 1')

await knex.raw('ALTER SEQUENCE cookies_id_seq RESTART WITH 1')

await knex.raw('ALTER SEQUENCE emails_id_seq RESTART WITH 1')
