Il servizio BigQuery ti consente di utilizzare l'API Google BigQuery in Apps Script. Questa API consente agli utenti di gestire i propri progetti BigQuery, caricare nuovi dati ed eseguire query.
Riferimento
Per informazioni dettagliate su questo servizio, consulta la documentazione di riferimento per l'API BigQuery.
Come tutti i servizi avanzati di Apps Script, il servizio BigQuery utilizza gli stessi oggetti, metodi e parametri dell'API pubblica. Per ulteriori informazioni, consulta Come vengono determinate le firme dei metodi.

Carica i dati CSV
Questo esempio crea una nuova tabella e vi carica un file CSV da Google Drive.
/** * Loads a CSV into BigQuery */functionloadCsv(){// Replace this value with the project ID listed in the Google// Cloud Platform project.constprojectId='XXXXXXXX';// Create a dataset in the BigQuery UI (https://bigquery.cloud.google.com)// and enter its ID below.constdatasetId='YYYYYYYY';// Sample CSV file of Google Trends data conforming to the schema below.// https://docs.google.com/file/d/0BwzA1Orbvy5WMXFLaTR1Z1p2UDg/editconstcsvFileId='0BwzA1Orbvy5WMXFLaTR1Z1p2UDg';// Create the table.consttableId='pets_'+newDate().getTime();lettable={tableReference:{projectId:projectId,datasetId:datasetId,tableId:tableId},schema:{fields:[{name:'week',type:'STRING'},{name:'cat',type:'INTEGER'},{name:'dog',type:'INTEGER'},{name:'bird',type:'INTEGER'}]}};try{table=BigQuery.Tables.insert(table,projectId,datasetId);console.log('Tablecreated:%s',table.id);}catch(err){console.log('unabletocreatetable');}// Load CSV data from Drive and convert to the correct format for upload.constfile=DriveApp.getFileById(csvFileId);constdata=file.getBlob().setContentType('application/octet-stream');// Create the data upload job.constjob={configuration:{load:{destinationTable:{projectId:projectId,datasetId:datasetId,tableId:tableId},skipLeadingRows:1}}};try{constjobResult=BigQuery.Jobs.insert(job,projectId,data);console.log(`Loadjobstarted.Status:${jobResult.status.state}`);}catch(err){console.log('unabletoinsertjob');}}
