datasets

Updates information in an existing dataset. The update method replaces the entire dataset resource, whereas the patch method only replaces fields that are provided in the submitted dataset resource. This method supports RFC5789 patch semantics. # IAM Permissions Requires the following IAM permission(s) to use this method: - bigquery.datasets.update on the dataset. - bigquery.datasets.get on the dataset.

patch/projects/{+projectId}/datasets/{+datasetId}

Path parameters

projectIdstring required

Required. Project ID of the dataset being updated

datasetIdstring required

Required. Dataset ID of the dataset being updated

Query parameters

accessPolicyVersioninteger

Optional. The version of the provided access policy schema. Valid values are 0, 1, and 3. Requests specifying an invalid value will be rejected. This version refers to the schema version of the access policy and not the version of access policy. This field's value can be equal or more than the access policy schema provided in the request. For example, * Operations updating conditional access policy binding in datasets must specify version 3. Some of the operations are : - Adding a new access policy entry with condition. - Removing an access policy entry with condition. - Updating an access policy entry with condition. * But dataset with no conditional role bindings in access policy may specify any valid value or leave the field unset. If unset or if 0 or 1 value is used for dataset with conditional bindings, request will be rejected. This field will be mapped to IAM Policy version (https://cloud.google.com/iam/docs/policies#versions) and will be used to set policy in IAM.

updateMode'UPDATE_MODE_UNSPECIFIED' | 'UPDATE_METADATA' | 'UPDATE_ACL' | 'UPDATE_FULL'

Optional. Specifies the fields of dataset that update/patch operation is targeting By default, both metadata and ACL fields are updated.

Request body

defaultCollationstring

Optional. Defines the default collation specification of future tables created in the dataset. If a table is created in this dataset without table-level default collation, then the table inherits the dataset default collation, which is applied to the string fields that do not have explicit collation specified. A change to this field affects only tables created afterwards, and does not alter the existing tables. The following values are supported: * 'und:ci': undetermined locale, case insensitive. * '': empty string. Default to case-sensitive behavior.

defaultTableExpirationMsstring int64

Optional. The default lifetime of all tables in the dataset, in milliseconds. The minimum lifetime value is 3600000 milliseconds (one hour). To clear an existing default expiration with a PATCH request, set to 0. Once this property is set, all newly-created tables in the dataset will have an expirationTime property set to the creation time plus the value in this property, and changing the value will only affect new tables, not existing ones. When the expirationTime for a given table is reached, that table will be deleted automatically. If a table's expirationTime is modified or removed before the table expires, or if you provide an explicit expirationTime when creating a table, that value takes precedence over the default expiration time indicated by this property.

labelsobject

The labels associated with this dataset. You can use these to organize and group your datasets. You can set this property when inserting or updating a dataset. See Creating and Updating Dataset Labels for more information.

locationstring

The geographic location where the dataset should reside. See https://cloud.google.com/bigquery/docs/locations for supported locations.

idstring

Output only. The fully-qualified unique name of the dataset in the format projectId:datasetId. The dataset name without the project name is given in the datasetId field. When creating a new dataset, leave this field blank, and instead specify the datasetId field.

satisfiesPzsboolean

Output only. Reserved for future use.

descriptionstring

Optional. A user-friendly description of the dataset.

storageBillingModel'STORAGE_BILLING_MODEL_UNSPECIFIED' | 'LOGICAL' | 'PHYSICAL'

Optional. Updates storage_billing_model for the dataset.

etagstring

Output only. A hash of the resource.

kindstring

Output only. The resource type.

lastModifiedTimestring int64

Output only. The date when this dataset was last modified, in milliseconds since the epoch.

creationTimestring int64

Output only. The time when this dataset was created, in milliseconds since the epoch.

typestring

Output only. Same as type in ListFormatDataset. The type of the dataset, one of: * DEFAULT - only accessible by owner and authorized accounts, * PUBLIC - accessible by everyone, * LINKED - linked dataset, * EXTERNAL - dataset with definition in external metadata catalog, * BIGLAKE_ICEBERG - a Biglake dataset accessible through the Iceberg API, * BIGLAKE_HIVE - a Biglake dataset accessible through the Hive API.

defaultPartitionExpirationMsstring int64

This default partition expiration, expressed in milliseconds. When new time-partitioned tables are created in a dataset where this property is set, the table will inherit this value, propagated as the TimePartitioning.expirationMs property on the new table. If you set TimePartitioning.expirationMs explicitly when creating a table, the defaultPartitionExpirationMs of the containing dataset is ignored. When creating a partitioned table, if defaultPartitionExpirationMs is set, the defaultTableExpirationMs value is ignored and the table will not be inherit a table expiration deadline.

satisfiesPziboolean

Output only. Reserved for future use.

selfLinkstring

Output only. A URL that can be used to access the resource again. You can use this URL in Get or Update requests to the resource.

catalogSourcestring

Output only. The origin of the dataset, one of: * (Unset) - Native BigQuery Dataset * BIGLAKE - Dataset is backed by a namespace stored natively in Biglake

defaultRoundingMode'ROUNDING_MODE_UNSPECIFIED' | 'ROUND_HALF_AWAY_FROM_ZERO' | 'ROUND_HALF_EVEN'

Optional. Defines the default rounding mode specification of new tables created within this dataset. During table creation, if this field is specified, the table within this dataset will inherit the default rounding mode of the dataset. Setting the default rounding mode on a table overrides this option. Existing tables in the dataset are unaffected. If columns are defined during that table creation, they will immediately inherit the table's default rounding mode, unless otherwise specified.

isCaseInsensitiveboolean

Optional. TRUE if the dataset and its table names are case-insensitive, otherwise FALSE. By default, this is FALSE, which means the dataset and its table names are case-sensitive. This field does not affect routine references.

friendlyNamestring

Optional. A descriptive name for the dataset.

resourceTagsobject

Optional. The tags attached to this dataset. Tag keys are globally unique. Tag key is expected to be in the namespaced format, for example "123456789012/environment" where 123456789012 is the ID of the parent organization or project resource for this tag key. Tag value is expected to be the short name, for example "Production". See Tag definitions for more details.

maxTimeTravelHoursstring int64

Optional. Defines the time travel window in hours. The value can be from 48 to 168 hours (2 to 7 days). The default value is 168 hours if this is not set.
