tBigQuerySQLRow – Docs for ESB 7.x


Connects to Google BigQuery and performs queries to select data from tables row by row or create or delete tables in Google BigQuery.

tBigQuerySQLRow Standard properties

These properties are used to configure tBigQuerySQLRow running in the Standard Job framework.

The Standard
tBigQueryInput component belongs to the Big Data family.

The component in this framework is available in all Talend

Basic settings

Schema and Edit Schema

A schema is a row description. It defines the number of fields
(columns) to be processed and passed on to the next component. When you create a Spark
Job, avoid the reserved word line when naming the

Click Edit
to make changes to the schema. If the current schema is of the Repository type, three options are available:

  • View schema: choose this
    option to view the schema only.

  • Change to built-in property:
    choose this option to change the schema to Built-in for local changes.

  • Update repository connection:
    choose this option to change the schema stored in the repository and decide whether
    to propagate the changes to all the Jobs upon completion. If you just want to
    propagate the changes to the current Job, you can select No upon completion and choose this schema metadata
    again in the Repository Content


Built-In: You create and store the schema locally for this component


Repository: You have already created the schema and stored it in the
Repository. You can reuse it in various projects and Job designs.

Authentication mode Select the mode to be used to authenticate to your project.

  • OAuth 2.0: authenticate the access using
    OAuth credentials. When selecting this mode, the parameters to be

    Basic settings view is Service
    account credentials file
Service account credentials file Enter the path to the credentials file created for the service account
to be used. This file must be stored in the machine in which your Talend Job is actually launched and

For further information about how to create a Google service
account and obtain the credentials file, see Getting Started with
from the Google documentation.

Client ID and Client

Paste the client ID and the client secret, both created and viewable on the
API Access tab view of the project hosting the Google BigQuery service and the Cloud
Storage service you need to use.

To enter the client secret, click the […] button next

Project ID

Paste the ID of the project hosting the Google BigQuery service you

API Console, or by hovering your mouse pointer over the name of the
project in the BigQuery Browser Tool.

Authorization code

Paste the authorization code provided by Google for the access you are

To obtain the authorization code, you need to execute the Job using this
component and when this Job pauses execution to print out an URL address, you
navigate to this address to copy the authorization code displayed.

Enter the query you need to use.

If the query to be used is the
legacy SQL of BigQuery, select this Use legacy
check box. For further information about this legacy
SQL, see Legacy SQL query reference
from the Google BigQuery documentation.

Advanced settings

token properties File Name

Enter the path to, or browse to the refresh token file you need to use.

At the first Job execution using the Authorization
you have obtained from Google BigQuery, the value in this field
is the directory and the name of that refresh token file to be created and used; if
that token file has been created and you need to reuse it, you have to specify its
directory and file name in this field.

With only the token file name entered,
Talend Studio
considers the directory of that token file to be the root of the Studio

For further information about the refresh token, see the manual of Google

Advanced Separator (for number)

Select this check box to change the separator used for the


Select the encoding from the list or select Custom

Global Variables

Global Variables

ERROR_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This
variable functions only if the Die on error check box is
cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable
functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl +
to access the variable list and choose the variable to use from it.

For further information about variables, see
Talend Studio

User Guide.


Usage rule

It can be a starting or an end component. When starting
a Job, it sends the extracted data to the component that follows it;
When ending a Job, it deletes a given table.

This component automatically detects and
supports both multi-regional locations and regional locations. When using the
regional locations, the buckets and the datasets to be used must be in the same
