Question

背景：我尝试从Google表格上传单个数据行并将其附加到BigQuery表格。

方法：我一直在使用https://developers.google.com/apps-script/advanced/bigquery来执行此操作，但不是像示例那样使用数据文件，而是使用自己的工作表来处理特定行的数据：

 var file = SpreadsheetApp.getActiveSpreadsheet();
  var currentSheet = file.getSheetByName(name);
  var lastRow = currentSheet.getLastRow()
   var lastC = currentSheet.getLastColumn()
   var rows = currentSheet.getRange(2,1,1,lastC).getValues();

＆＃34;行＆＃34;是要导入BQ的数据行。我已经尝试了很多东西，根据另一个StackOverflow question，＆＃34; rowsCSV＆＃34;使2D数组值为CSV。

  var rowsCSV = rows.join("\n");

 var data = rowsCSV.getBlob().setContentType('application/octet-stream');

问题：每次运行该函数时，都会收到错误＆＃34;无法在对象Blob中找到函数getBlob。＆＃34;或者，＆＃34;无法将数组转换为（类）[] []＆＃34;或＆＃34;无法在对象中找到函数getBlob Tue May 16 2017 00:00:00 GMT + 0200（CEST），58072.4 ,,,,,,,,,,, test＆＃34;，其中最后一位（＆＃34; Tue May ..＆＃34;）是该行的实际数据。

我在这里做错了什么？

Answer 1

数组没有getBlob方法。您必须使用Utilities.newBlob()从字符串中获取blob。您可以在同一here

上找到相关文档

 var rowsCSV = rows.join("\n");
 var blob = Utilities.newBlob(rowsCSV, "text/csv")
 Logger.log(blob.getDataAsString())
 var data = blob.setContentType('application/octet-stream');

等效地你可以这样做

var rowsCSV = rows.join("\n");
var data = Utilities.newBlob(rowsCSV, 'application/octet-stream')

基于@JackBrown给出的更正，我已经编辑了代码，但是无法将数据推送到Big Query。下面的代码创建表，但不要推送值。

    /**
 * Loads a CSV into BigQuery
 */
function loadCsv() {
  // Replace this value with the project ID listed in the Google
  // Cloud Platform project.
  var projectId = 'master-ad-data';
  // Create a dataset in the BigQuery UI (https://bigquery.cloud.google.com)
  // and enter its ID below.
  var datasetId = 'DataImportFromSpreadsheet';
  // Sample CSV file of Google Trends data conforming to the schema below.
  // https://docs.google.com/file/d/0BwzA1Orbvy5WMXFLaTR1Z1p2UDg/edit
  var csvFileId = '17kYH6hP2RlsFeUmwM1v6WOgm2FKrwLTXWDhA2ZLISN8';
  var name = 'Sheet1';

  // Create the table.
  var tableId = 'pets_' + new Date().getTime();
  var table = {
    tableReference: {
      projectId: projectId,
      datasetId: datasetId,
      tableId: tableId
    },
    schema: {
      fields: [
        {name: 'CampaignLabels', type: 'STRING'},
        {name: 'ImpressionShare', type: 'INTEGER'}
      ]
    }
  };
  table = BigQuery.Tables.insert(table, projectId, datasetId);
  Logger.log('Table created: %s', table.id);


  var file = SpreadsheetApp.getActiveSpreadsheet();
  var currentSheet = file.getSheetByName(name);
  var lastRow = currentSheet.getLastRow()
  var lastC = currentSheet.getLastColumn()
  var rows = currentSheet.getRange(2,1,1,lastC).getValues();

  var rowsCSV = rows.join("\n");
  Logger.log("Check This"+" "+rowsCSV);
  var data = Utilities.newBlob(rowsCSV, 'application/octet-stream')

  // Create the data upload job.
  var job = {
    configuration: {
      load: {
        destinationTable: {
          projectId: projectId,
          datasetId: datasetId,
          tableId: tableId
        },
        skipLeadingRows: 1
      }
    }
  };
  job = BigQuery.Jobs.insert(job, projectId, data);
  Logger.log('Load job started. Check on the status of it here: ' +
      'https://bigquery.cloud.google.com/jobs/%s', projectId);
}

对于其他人，杰克·布朗的答案是正确的，您只需要更改

var rows = currentSheet.getRange(2,1,1,lastC).getValues();

到

var rows = currentSheet.getRange(2,1,lastRow,lastC).getValues();

Apps Script，将Sheet范围转换为Blob
