API for bigquery.tabledata.insertAll method - google-cloud-platform

Question

Below is my code for writing into a BigQuery table:
from google.cloud import bigquery
response = bigquery.tabledata.insertAll(projectId=PROJECT_ID,datasetId=DATASET_ID,
tableId=TABLE_ID,
body=data).execute()
However, I'm getting the following error:
no module tabledata in google.cloud.bigquery
Can anyone help me with this?
Which API should I use here?

Answer 1

Please, check the Streaming data into BigQuery documentation. When using python you need to use following function:
insert_rows(table, rows, selected_fields=None, **kwargs)
which insert rows into a table via the streaming API. For more information refer to following BigQuery Python API reference documentation.
You can check Python streaming insert example:
# TODO(developer): Import the client library.
# from google.cloud import bigquery
# TODO(developer): Construct a BigQuery client object.
# client = bigquery.Client()
# TODO(developer): Set table_id to the ID of the model to fetch.
# table_id = "your-project.your_dataset.your_table"
table = client.get_table(table_id) # Make an API request.
rows_to_insert = [(u"Phred Phlyntstone", 32), (u"Wylma Phlyntstone", 29)]
errors = client.insert_rows(table, rows_to_insert) # Make an API request.
if errors == []:
print("New rows have been added.")
You can also use API, calling tabledata.insertAll method to see the request and response of API. You need to specify projectId, datasetId, tableId. You can see JavaScript code snippet that is used to perform request:
function execute() {
return gapi.client.bigquery.tabledata.insertAll({
"projectId": "<your_projectId>",
"datasetId": "<your_datasetId>",
"tableId": "<your_tableId>",
"resource": {}
})
.then(function(response) {
// Handle the results here (response.result has the parsed body).
console.log("Response", response);
},
function(err) { console.error("Execute error", err); });
}
Let me know about the results.
