Predefined roles and permissions

This page provides information on Identity and Access Management (IAM) roles and permissions for BigQuery.

This page includes roles and permissions relevant to each of BigQuery's companion products:

  • BigQuery ML
  • BigQuery Data Transfer Service
  • BigQuery BI Engine

For additional information on access controls in BigQuery ML, see Access control in the BigQuery ML documentation.

Overview

When an identity calls a Google Cloud API, BigQuery requires that the identity has the appropriate permissions to use the resource. You can grant permissions by granting roles to a user, a group, or a service account.

This page describes the BigQuery IAM roles that you can grant to identities to access BigQuery resources.

IAM role types

There are three types of roles in IAM:

  • Basic roles include the Owner, Editor, and Viewer roles. The basic roles represent the access controls that existed prior to the introduction of IAM.

  • Predefined roles provide granular access for a specific service and are managed by Google Cloud. Predefined roles are meant to support common use cases and access control patterns.

  • Custom roles provide granular access according to a user-specified list of permissions.

To determine if one or more permissions are included in a basic, predefined, or custom role, you can use one of the following methods:

When you assign both predefined and basic roles to a user, the permissions granted are a union of each role's permissions.

For additional information on using IAM to access resources, see Granting, changing, and revoking access to resources in the IAM documentation.

For information on creating custom roles, see Creating and managing custom roles in the IAM documentation.

BigQuery permissions and predefined IAM roles

To grant access to a BigQuery resource, assign one or more roles to a user, group, or service account. You can grant access at the following BigQuery resource levels:

  • organization or Google Cloud project level
  • dataset level
  • table or view level

Roles applied at an organization or Cloud project level

When you assign roles at the organization and project level, you provide permission to run BigQuery jobs or to access all of a project's BigQuery resources.

Roles applied at a dataset level

You can assign roles at the dataset level to provide access to a specific dataset, without providing complete access to the project's resources. In the IAM policy hierarchy, BigQuery datasets are child resources of projects. For more information on assigning roles at the dataset level, see Controlling access to datasets.

Roles applied to individual resources within datasets

You can assign roles individually to certain types of resources within datasets, without providing complete access to the dataset's resources.

Roles can be applied to individual resources of the following types:

  • tables
  • views

Roles cannot be applied to individual resources of the following types:

  • routines
  • models

For more information on assigning roles at the table or view level, see Controlling access to tables or views.
