Basic create-read-update-delete verbs for tables, as well as functions for uploading and downloading data in to/from memory (bq_table_upload(), (bq_table_download())), and saving to/loading from Google CloudStorage (bq_table_load(), bq_table_save()).

bq_table_create(x, fields = NULL, ...)

bq_table_meta(x, fields = NULL)

bq_table_fields(x)

bq_table_size(x)

bq_table_nrow(x)

bq_table_exists(x)

bq_table_delete(x)

bq_table_copy(x, dest, ..., quiet = NA)

bq_table_upload(x, values, ..., quiet = NA)

bq_table_save(x, destination_uris, ..., quiet = NA)

bq_table_load(x, source_uris, ..., quiet = NA)

bq_table_patch(x, fields)

Arguments

x

A bq_table, or an object coercible to a bq_table.

fields

A bq_fields specification, or something coercible to it (like a data frame).

...

Additional arguments passed on to the underlying API call. snake_case names are automatically converted to camelCase.

dest

Source and destination bq_tables.

quiet

If FALSE, displays progress bar; if TRUE is silent; if NA displays progress bar only for long-running jobs.

values

Data frame of values to insert.

destination_uris

A character vector of fully-qualified Google Cloud Storage URIs where the extracted table should be written. Can export up to 1 Gb of data per file. Use a wild card URI (e.g. gs://[YOUR_BUCKET]/file-name-*.json) to automatically create any number of files.

source_uris

The fully-qualified URIs that point to your data in Google Cloud.

For Google Cloud Storage URIs: Each URI can contain one `'*'`` wildcard character and it must come after the 'bucket' name. Size limits related to load jobs apply to external data sources.

For Google Cloud Bigtable URIs: Exactly one URI can be specified and it has be a fully specified and valid HTTPS URL for a Google Cloud Bigtable table. For Google Cloud Datastore backups: Exactly one URI can be specified. Also, the '*' wildcard character is not allowed.

Value

  • bq_table_copy(), bq_table_create(), bq_table_delete(), bq_table_upload(): an invisible bq_table

  • bq_table_exists(): either TRUE or FALSE.

  • bq_table_download(): a data frame

  • bq_table_size(): the size of the table in bytes

  • bq_table_fields(): a bq_fields.
