tEXARow – Docs for ESB 7.x


Executes SQL queries on an EXASolution database.

Depending on the nature of the query and the database,
tEXARow acts on the actual structure of the database, or indeed the
data, although without modifying them. The Row suffix indicates that it is used to channel a
flow in a Job although it does not produce any output data.

tEXARow Standard properties

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

The Standard
tEXARow component belongs to the Databases family.

The component in this framework is available in all Talend

Note: This component is a specific version of a dynamic database
connector. The properties related to database settings vary depending on your database
type selection. For more information about dynamic database connectors, see Dynamic database components.

Basic settings


Select a type of database from the list and click

Property Type

Either Built-In or Repository.

  • Built-In: No property data
    stored centrally.

  • Repository: Select the
    repository file in which the properties are stored. The database
    connection fields that follow are completed automatically using
    the data retrieved.

Use an existing connection

Select this check box and from the list displayed select the
relevant connection component to reuse the connection details you have 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 host or host list of the EXASol database servers. EXASol can run in a cluster
environment. The valid value can be a simple IP address (for example,, an IP range list (for example, that represents three servers,, and, or a
comma-separated host list (for example, server1,server2,server3) of the EXASolution database cluster.


Enter the listening port number of the EXASolution database cluster.

Schema name

Enter the name of the schema you want to use.

Username and Password

Enter the user authentication data to access the EXASolution database.

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.

Schema and Edit

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

Table Name

Enter the name of the table to be processed.

Query Type

Either Built-In or Repository

  • Built-In: Enter the query
    manually or with the help of the SQLBuilder.

  • Repository: Select the
    appropriate query from the Repository. The Query field is then completed

Guess Query

Click the Guess Query button to
generate the query that corresponds to the table schema in the Query field.


Enter the database query paying particularly attention to the proper
sequence of the fields in order to match the schema definition.

Die on error

Select the check box to stop the execution of the Job when an error

Clear the check box to skip any rows on error and complete the process for
error-free rows. When errors are skipped, you can collect the rows on error using a Row > Reject link.

Advanced settings

Additional JDBC parameters

Specify additional connection properties for the database connection you are
creating. The properties are separated by semicolon and each property is a key-value
pair, for example, encryption=1;clientname=Talend.

This field is not available if the Use an existing
check box is selected.

Propagate QUERY’s recordset

Select this check box to insert the query results in one of the flow
columns. Select the particular column from the use

Use PreparedStatement

Select this check box to use prepared statements and in the Set PreparedStatement Parameters table
displayed, add as many parameters as needed and set the following
attributes for each parameter:

  • Parameter Index: enter the
    index of the prepared statement parameter.

  • Parameter Type: click in the
    cell and select the type of the parameter from the list.

  • Parameter Value: enter the
    value of the parameter.

Commit every

Enter the number of rows to be included in each batch before the data
is written. This option guarantees the quality of the transaction
(although there is no rollback option) and improves performance.

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

QUERY: the query statement being processed. This is a Flow
variable and it returns a string.

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.
