Class DataSourceSpecBuilder

  • DataSourceSpecBuilder is used to create a specification for data sources connected to a database.

  • To start building a specification, use SpreadsheetApp.newDataSourceSpec().

  • Specific database types like BigQuery and Looker have dedicated builder methods like asBigQuery() and asLooker().

  • The build() method is used to finalize the specification from the builder's settings.
DataSourceSpecBuilder

The builder for DataSourceSpec. To create a specification for certain type, use as...() method. To create a new builder, use SpreadsheetApp.newDataSourceSpec(). To use the specification, see DataSourceTable.

Only use this class with data that’s connected to a database.

This example shows how to build a BigQuery data source specification. 

const spec = SpreadsheetApp.newDataSourceSpec()
                 .asBigQuery()
                 .setProjectId('big_query_project')
                 .setRawQuery('select @FIELD from table limit @LIMIT')
                 .setParameterFromCell('FIELD', 'Sheet1!A1')
                 .setParameterFromCell('LIMIT', 'namedRangeCell')
                 .build();

This example shows how to build a Looker data source specification. It returns a LookerDataSourceSpec object after using build(). 

const spec = SpreadsheetApp.newDataSourceSpec()
                 .asLooker()
                 .setInstanceUrl('https://looker_instance_url.com')
                 .setModelName('model_name')
                 .setExploreName('explore_name')
                 .build();

Detailed documentation

asBigQuery()

Gets the builder for BigQuery data source.

Return

BigQueryDataSourceSpecBuilder — The BigQuery data source specification builder.

asLooker()

Gets the builder for Looker data source. 

const spec = SpreadsheetApp.newDataSourceSpec()
                 .asLooker()
                 .setInstanceUrl('https://looker_instance_url.com')
                 .setModelName('model_name')
                 .setExploreName('explore_name')
                 .build();

Return

LookerDataSourceSpecBuilder — The Looker data source specification builder.

build()

Builds a data source specification from the settings in this builder. Must use as...() to specify a data source type before building.

The following code sample builds a BigQuery DataSource Spec. 

const bigQueryDataSourceSpec = SpreadsheetApp.newDataSourceSpec().asBigQuery();
// TODO(developer): Replace with the required dataset, project and table IDs.
bigQueryDataSourceSpec.setDatasetId('my data set id');
bigQueryDataSourceSpec.setProjectId('my project id');
bigQueryDataSourceSpec.setTableId('my table id');

bigQueryDataSourceSpec.build();

The following code sample builds a Looker DataSource Spec. 

const lookerDataSourceSpecBuilder =
    SpreadsheetApp.newDataSourceSpec().asLooker();
const lookerSpec = lookerDataSourceSpecBuilder.setExploreName('my explore name')
                       .setInstanceUrl('my instance url')
                       .setModelName('my model name')
                       .build();

Return

DataSourceSpec — The data source specification.

copy()

Creates a DataSourceSpecBuilder based on this data source’s settings. 

// TODO(developer): Replace the URL with your own.
const ss = SpreadsheetApp.openByUrl(
    'https://docs.google.com/spreadsheets/d/abc123456/edit',
);
const spec = ss.getDataSources()[0].getSpec();

const newSpec = spec.copy();

Return

DataSourceSpecBuilder — The builder.

getParameters()

Gets the parameters of the data source. 

// TODO(developer): Replace the URL with your own.
const ss = SpreadsheetApp.openByUrl(
    'https://docs.google.com/spreadsheets/d/abc123456/edit',
);
const spec = ss.getDataSources()[0].getSpec();
const parameters = spec.getParameters();

This method is only available for BigQuery data sources.

Return

DataSourceParameter[] — The parameter list.

getType()

Gets the type of the data source. 

// TODO(developer): Replace the URL with your own.
const ss = SpreadsheetApp.openByUrl(
    'https://docs.google.com/spreadsheets/d/abc123456/edit',
);
const spec = ss.getDataSources()[0].getSpec();
const type = spec.getType();

Return

DataSourceType — The data source type.

removeAllParameters()

Removes all the parameters. 

const specBuilder = SpreadsheetApp.newDataSourceSpec();
specBuilder.removeAllParameters();

Return

DataSourceSpecBuilder — The builder, for chaining.

removeParameter(parameterName)

Removes the specified parameter. 

const specBuilder = SpreadsheetApp.newDataSourceSpec();
specBuilder.removeParameter('x');

Parameters

NameTypeDescription
parameterNameStringThe name of the parameter to remove.

Return

DataSourceSpecBuilder — The builder, for chaining.

setParameterFromCell(parameterName, sourceCell)

Adds a parameter, or if the parameter with the name exists, updates its source cell for data source spec builders of type DataSourceType.BIGQUERY.

This method is only available for BigQuery data sources. 

const specBuilder = SpreadsheetApp.newDataSourceSpec().asBigQuery();
specBuilder.setParameterFromCell('x', 'A1');
const bigQuerySpec = specBuilder.build();

Parameters

NameTypeDescription
parameterNameStringThe parameter name.
sourceCellStringThe source cell, as specified in A1 notation.

Return

DataSourceSpecBuilder — The builder, for chaining.
