ObjectVersions
Returns information for object versions inside a specific bucket.
Table Specific Information
Select
The driver will use the Google Cloud Storage API to process WHERE clause conditions built with the following column and operator. The rest of the filter is executed client side within the driver.
- Bucket supports the '=' comparison.
- Name supports the '=' comparison.
For example, the following queries are processed server side:
SELECT * FROM ObjectVersions WHERE Name = 'TestName' SELECT * FROM ObjectVersions WHERE Bucket = 'TestBucket'
Columns
| Name | Type | Description |
| Id | String | The ID of the object, including the bucket name, object name, and generation number. |
| Name [KEY] | String | The name of the object. Required if not specified by URL parameter. |
| Bucket | String | The name of the bucket containing this object. |
| Generation | String | The content generation of this object. Used for object versioning. |
| MetaGeneration | String | The version of the metadata for this object at this generation. Used for preconditions and for detecting changes in metadata. A metageneration number is only meaningful in the context of a particular generation of a particular object. |
| ContentType | String | Content-Type of the object data. If an object is stored without a Content-Type, it is served as application/octet-stream. |
| TimeCreated | Datetime | The creation time of the object in RFC 3339 format. |
| Updated | Datetime | The modification time of the object metadata in RFC 3339 format. |
| TimeDeleted | Datetime | The deletion time of the object in RFC 3339 format. Returned if and only if this version of the object is no longer a live version, but remains in the bucket as a noncurrent version. |
| TemporaryHold | Boolean | Whether or not the object is subject to a temporary hold. |
| EventBasedHold | Boolean | Whether or not the object is subject to an event-based hold. |
| RetentionExpirationTime | Datetime | The earliest time that the object can be deleted, based on a bucket's retention policy, in RFC 3339 format. |
| StorageClass | String | Storage class of the object. |
| TimeStorageClassUpdated | Datetime | The time at which the object's storage class was last changed. When the object is initially created, it will be set to timeCreated. |
| Size | String | Content-Length of the data in bytes. |
| Md5Hash | String | MD5 hash of the data; encoded using base64. For more information about using the MD5 hash, see Hashes and ETags: Best Practices. |
| MediaLink | String | Media download link. |
| ContentEncoding | String | Content-Encoding of the object data. |
| ContentDisposition | String | Content-Disposition of the object data. |
| ContentLanguage | String | Content-Language of the object data. |
| CacheControl | String | Cache-Control directive for the object data. If omitted, and the object is accessible to all anonymous users, the default will be public, max-age=3600. |
| OwnerEntity | String | The entity, in the form user-emailAddress. |
| OwnerEntityId | String | The ID for the entity. |
| Crc32c | String | CRC32c checksum, as described in RFC 4960, Appendix B; encoded using base64 in big-endian byte order. For more information about using the CRC32c checksum, see Hashes and ETags: Best Practices. |
| ComponentCount | Integer | Number of underlying components that make up a composite object. Components are accumulated by compose operations, counting 1 for each non-composite source object and componentCount for each composite source object. Note: componentCount is included in the metadata for composite objects only. |
| Etag | String | HTTP 1.1 Entity tag for the object. |
| CustomerEncryptionAlgorithm | String | The encryption algorithm. |
| CustomerEncryptionKeySha256 | String | SHA256 hash value of the encryption key. |
| KmsKeyName | String | Cloud KMS Key used to encrypt this object, if the object is encrypted by such a key. |
| CustomTime | Datetime | CA user-specified timestamp for the object in RFC 3339 format. |
