Running knex migrations

[carlosfaria94]

Hi, first of all, thank you for this amazing package!

I configured pg-mem with knex, like this:

  const mem = newDb()
  knex = mem.adapters.createKnex(0, {
    ...databaseOpts,
    ...knexSnakeCaseMappers(),
  })

And then I executed await knex.migrate.latest(), starting all migration files. But it fails in the first migration:

import * as Knex from 'knex'

export async function up(knex: Knex): Promise<void> {
  return knex.schema
    .createTable('update_times', function (table) {
      table.string('id', 50).unique().notNullable().primary()
      table.dateTime('update_time').notNullable()
    })
    .createTable('room_board_types', function (table) {
      table.string('id', 2).unique().notNullable().primary()
      table.string('name', 100).notNullable()
      table.boolean('enabled').notNullable().defaultTo(false)
      table.boolean('package').notNullable().defaultTo(false)
    })
    .createTable('room_types', function (table) {
      table.string('id', 3).unique().notNullable().primary()
      table.string('name', 100).notNullable()
      table.boolean('enabled').notNullable().defaultTo(false)
      table.boolean('package').notNullable().defaultTo(false)
    })
    .createTable('room_characteristics', function (table) {
      table.string('id', 10).unique().notNullable().primary()
      table.string('name', 100).nullable()
      table.boolean('enabled').notNullable().defaultTo(true)
    })
    .createTable('room_types_characteristics', function (table) {
      table.string('type_id', 3).notNullable().references('id').inTable('room_types')
      table.string('characteristic_id', 10).notNullable().references('id').inTable('room_characteristics')
      table.primary(['type_id', 'characteristic_id'])
    })
}

export async function down(knex: Knex): Promise<void> {
  return knex.schema
    .dropTableIfExists('room_types_characteristics')
    .dropTableIfExists('room_characteristics')
    .dropTableIfExists('room_types')
    .dropTableIfExists('room_board_types')
    .dropTableIfExists('update_times')
}

And then I get the following error from pg-mem:

🔨 Not supported 🔨 : get pg fields

What I'm doing wrong?

Thanks

Hi !
You are doing nothing wrong... knexSnakeCaseMappers() is just reading a field that is not supported.

Fix shipped with pg-mem@1.9.15 !

And thanks for the kind words

It solved the problem, thank you!

@oguimbal but I'm now getting another error, should I create a new issue or discussion?

I think knex generates SQL that is not compatible with pg-mem:

    SAVEPOINT trx3; - 💔 Your query failed to parse.
    This is most likely due to a SQL syntax error. However, you might also have hit a bug, or an unimplemented feature of pg-mem.
    If this is the case, please file an issue at https://github.com/oguimbal/pg-mem along with a query that reproduces this syntax error.

    👉 Failed query:

        SAVEPOINT trx3;;

    💀 Syntax error at line 1 col 11:

      SAVEPOINT trx3
                ^
    Unexpected word token: "trx3". I did not expect any more input. Here is the state of my parse table:

hi @oguimbal
the error with SAVEPOINT trx3 still exists a few years later
any chance it is going to be supported ?
