Interface DataSourceSpec

Access the general settings of an existing data source spec. To access data source spec for certain type, use as...() method. To create a new data source spec, use SpreadsheetApp.newDataSourceSpec().

This example shows how to get information from a BigQuery data source spec.

var dataSourceTable =
    SpreadsheetApp.getActive().getSheetByName("Data Sheet 1").getDataSourceTables()[0];
var spec = dataSourceTable.getDataSource().getSpec();
if (spec.getType() == SpreadsheetApp.DataSourceType.BIGQUERY) {
  var bqSpec = spec.asBigQuery();
  Logger.log("Project ID: %s\n", bqSpec.getProjectId());
  Logger.log("Raw query string: %s\n", bqSpec.getRawQuery());
}
