Query Query

yaml
type: "io.kestra.plugin.gcp.bigquery.Query"

Execute BigQuery SQL query in a specific BigQuery database.

Examples

Create a table with a custom query.

yaml
id: gcp_bq_query
namespace: company.team

tasks:
  - id: query
    type: io.kestra.plugin.gcp.bigquery.Query
    destinationTable: "my_project.my_dataset.my_table"
    writeDisposition: WRITE_APPEND
    sql: |
      SELECT
        "hello" as string,
        NULL AS `nullable`,
        1 as int,
        1.25 AS float,
        DATE("2008-12-25") AS date,
        DATETIME "2008-12-25 15:30:00.123456" AS datetime,

Execute a query and fetch results sets on another task.

yaml
id: gcp_bq_query
namespace: company.team

tasks:
  - id: fetch
    type: io.kestra.plugin.gcp.bigquery.Query
    fetch: true
    sql: |
      SELECT 1 as id, "John" as name
      UNION ALL
      SELECT 2 as id, "Doe" as name
  - id: use_fetched_data
    type: io.kestra.plugin.core.debug.Return
    format: |
      {% for row in outputs.fetch.rows %}

      {% endfor %}

Properties

allowLargeResults

  • Type: boolean

If not provided, a new table is created.

dryRun

  • Type: boolean
  • Dynamic:
  • Required:

A valid query will mostly return an empty response with some processing statistics, while an invalid query will return the same error as it would if it were an actual run.

fetch

  • Dynamic:
  • Required:
  • Default: false

Whether to Fetch the data from the query result to the task output

fetchOne

  • Type: boolean

Whether to Fetch only one data row from the query result to the task output

flattenResults

  • Type: boolean
  • Dynamic:
  • Required:
  • Default: true

Sets whether nested and repeated fields should be flattened.

If set to false, allowLargeResults must be true.

jobTimeout

  • Type: string
  • Dynamic:
  • Required:
  • Format: duration

Job timeout.

If this time limit is exceeded, BigQuery may attempt to terminate the job.

labels

  • Type: object
  • SubType: string
  • Dynamic: ✔️
  • Required:

The labels associated with this job.

You can use these to organize and group your jobs. Label keys and values can be no longer than 63 characters, can only contain lowercase letters, numeric characters, underscores and dashes. International characters are allowed. Label values are optional. Label keys must start with a letter and each label in the list must have a different key.

legacySql

  • Type: boolean
  • Dynamic:

  • Default: false

Whether to use BigQuery's legacy SQL dialect for this query

By default this property is set to false.

location

  • Required:

The geographic location where the dataset should reside.

This property is experimental and might be subject to change or removed.

See Dataset Location

maxResults

  • Type: integer
  • Dynamic:
  • Required:

This is only supported in the fast query path.

The maximum number of rows of data to return per page of results. Setting this flag to a small value such as 1000 and then paging through results might improve reliability when the query result set is large. In addition to this limit, responses are also limited to 10 MB. By default, there is no maximum row count, and only the byte limit applies.

maximumBillingTier

  • Type: integer
  • Dynamic:
  • Required:

Limits the billing tier for this job.

Queries that have resource usage beyond this tier will fail (without incurring a charge). If unspecified, this will be set to your project default.

maximumBytesBilled

  • Type: integer
  • Dynamic:
  • Required:

Limits the bytes billed for this job.

Queries that will have bytes billed beyond this limit will fail (without incurring a charge). If unspecified, this will be set to your project default.

  • Dynamic: ✔️
  • Required:
  • Default: [rateLimitExceeded, jobBackendError, internalError, jobInternalError]

schemaUpdateOptions

  • Type: array

  • Dynamic:
  • Required:

Experimental Options allowing the schema of the destination table to be updated as a side effect of the query job.

Schema update options are supported in two cases: * when writeDisposition is WRITE_APPEND;

  • when writeDisposition is WRITE_TRUNCATE and the destination table is a partition of a table, specified by partition decorators. For normal tables, WRITE_TRUNCATE will always overwrite the schema.

useQueryCache

  • Type: boolean
  • Dynamic:
  • Required:

Sets whether to look for the result in the query cache.

The query cache is a best-effort cache that will be flushed whenever tables in the query are modified. Moreover, the query cache is only available when destinationTable is not set

  • Required:
  • Possible Values:
