tServiceNowInput – Docs for ESB 7.x


Accesses ServiceNow and retrieves data from it.

tServiceNowInput retrieves data from ServiceNow
according to the specified conditions.

tServiceNowInput Standard properties

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

The Standard
tServiceNowInput component belongs to the Business and the Cloud families.

The component in this framework is available in all Talend

Basic settings

Use Existing Connection

Select this check box and in the Component List click the relevant connection component to
reuse the connection details you already defined.

Note: When a Job contains the parent Job and the child Job, if you
need to share an existing connection between the two levels, for example, to share the
connection created by the parent Job with the child Job, you have to:

  1. In the parent level, register the database connection
    to be shared in the Basic
    view of the connection component which creates that very database

  2. In the child level, use a dedicated connection
    component to read that registered database connection.

For an example about how to share a database connection
across Job levels, see

Talend Studio
User Guide


Enter the URL of the ServiceNow instance to be connected.

Username and Password

Enter the user authentication data to connect to the ServiceNow instance.

To enter the password, click the […] button next to the
password field, and then in the pop-up dialog box enter the password between double quotes
and click OK to save the settings.


Select the name of the table from which the
data will be retrieved or select Use
Custom Table
and in the Custom Table Name field displayed enter the
table name.

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

  • 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.


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


Specify search conditions to retrieve only the
data that matches the criteria by clicking the [+] button to add as many conditions as needed
and then setting the following parameters for each condition:

  • Input column:
    click in the cell and select the column of the input schema on which the
    search condition is to be set.

  • Operator: click in
    the cell and select an operator for the search condition.

  • Value: enter the
    value for the corresponding column for the search condition.

Advanced settings

Trim all columns

Select this check box to remove the leading and
trailing whitespaces from all columns.


Enter the maximum number of records to be


Select this check box to enter filtering conditions combined with AND and OR
logical operators. You can enter query statements in this field through
copy/paste operations. For information about the logical operators, see Operators available for filters and
and Generate an encoded query string through a filter.

The Conditions field in
the Basic settings view is not available
if you select this check box.

tStatCatcher Statistics

Select this check box to gather the Job
processing metadata at the Job level as well as at each component level.

Global Variables

Global Variables 

NB_LINE: the number of rows processed. This is an After
variable and it returns an integer.

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

This component is usually used as a start
component in a
flow and it requires an output component.

Dynamic settings

Click the [+] button to add a row in the table
and fill the Code field with a context
variable to choose your database connection dynamically from multiple
connections planned in your Job. This feature is useful when you need to
access database tables having the same data structure but in different
databases, especially when you are working in an environment where you
cannot change your Job settings, for example, when your Job has to be
deployed and executed independent of Talend Studio.

The Dynamic settings table is
available only when the Use an existing
check box is selected in the Basic settings view. Once a dynamic parameter is
defined, the Component List box in the
Basic settings view becomes unusable.

For examples on using dynamic parameters, see Reading data from databases through context-based dynamic connections and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic
and context variables, see Talend Studio
User Guide.
