Practice - 5 Tasks

1fill in blank

easy

Complete the command to rollback the last migration in Supabase CLI.

Supabase

supabase migration [1]

Drag options to blanks, or click blank then click option'

Aapply

Bstatus

Ccreate

Drollback

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'apply' instead of 'rollback' will apply migrations instead of undoing them.

Using 'create' is for making new migrations, not rolling back.

The rollback command undoes the last applied migration in Supabase.

2fill in blank

medium

Complete the command to rollback migrations by specifying the number of steps.

Supabase

supabase migration rollback --steps [1]

Drag options to blanks, or click blank then click option'

Aall

B1

C0

D-1

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'all' is not valid for the steps option.

Using '0' means no rollback will happen.

Using --steps 1 rolls back the last migration step.

3fill in blank

hard

Fix the error in the command to rollback migrations by adding the missing flag.

Supabase

supabase migration rollback [1] 2

Drag options to blanks, or click blank then click option'

A--steps

B--number

C--migrate

D--count

Attempts:

3 left

💡 Hint

Common Mistakes

Using '--count' or '--number' are not recognized flags for rollback steps.

Omitting the flag causes the command to fail.

The correct flag to specify how many migrations to rollback is --steps.

4fill in blank

hard

Fill both blanks to rollback migrations and confirm the action automatically.

Supabase

supabase migration rollback [1] 1 [2]

Drag options to blanks, or click blank then click option'

A--steps

B--force

C--confirm

D--dry-run

Attempts:

3 left

💡 Hint

Common Mistakes

Using '--confirm' instead of '--force' does not skip prompts.

Using '--dry-run' only simulates rollback without applying it.

Use --steps to specify how many migrations to rollback and --force to skip confirmation prompts.

5fill in blank

hard

Fill all three blanks to rollback two migrations quietly and specify the project directory.

Supabase

supabase migration rollback [1] 2 [2] --project-dir [3]

Drag options to blanks, or click blank then click option'

A--steps

B--force

C./my-project

D--quiet

Attempts:

3 left

💡 Hint

Common Mistakes

Using '--quiet' instead of '--force' does not skip confirmation prompts.

Omitting the project directory causes the command to run in the current folder.

Use --steps to set rollback count, --force to skip confirmation, and --project-dir to specify the project folder path.
