R: Submit query to BigQuery

bq_query {bigrquery} | R Documentation

## Submit query to BigQuery

### Description

These submit a query (using `bq_perform_query()`) and then wait for it complete (with `bq_job_wait()`). All BigQuery queries save their results into a table (temporary or otherwise), so these functions return a bq_table which you can then query for more information.

### Usage

    bq_project_query(x, query, destination_table = NULL, ..., quiet = NA)

    bq_dataset_query(
      x,
      query,
      destination_table = NULL,
      ...,
      billing = NULL,
      quiet = NA
    )

### Arguments

`x` | Either a project (a string) or a bq_dataset.
`query` | SQL query string.
`destination_table` | A bq_table where results should be stored. If not supplied, results will be saved to a temporary table that lives in a special dataset. You must supply this parameter for large queries (> 128 MB compressed).
`...` | Passed on to `bq_perform_query()`
`quiet` | If `FALSE`, displays progress bar; if `TRUE` is silent; if `NA` displays progress bar only for long-running jobs.
`billing` | If you query a dataset that you only have read access for, such as a public dataset, you must also submit a `billing` project.

### Value

A bq_table

### Examples

    if (bq_testable()) {
    # Querying a project requires full name in query
    tb <- bq_project_query(
      bq_test_project(),
      "SELECT count(*) FROM publicdata.samples.natality"
    )
    bq_table_fields(tb)
    bq_table_download(tb)

    # Querying a dataset sets default dataset so you can use bare table name,
    # but for public data, you'll need to set a project to bill.
    ds <- bq_dataset("publicdata", "samples")
    tb <- bq_dataset_query(ds,
      query = "SELECT count(*) FROM natality",
      billing = bq_test_project()
    )
    bq_table_download(tb)

    tb <- bq_dataset_query(ds,
      query = "SELECT count(*) FROM natality WHERE state = @state",
      parameters = list(state = "KS"),
      billing = bq_test_project()
    )
    bq_table_download(tb)
    }
