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

The Standard tAzureSynapseRow component belongs to two families: Cloud and Databases.

The component in this framework is available in all Talend products.

Basic settings

Use an existing connection

Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined.

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

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

Warning: If this component is configured to perform operations to a table, it is strongly recommended that you use an existing connection with the auto-commit function enabled for this comppnent. You can establish a connection of this type using the tAzureSynapseConnection component, with the Auto Commit option selected in the Advanced settings view.

Property Type

Select the way the connection details will be set.

  • Built-In: The connection details will be set locally for this component. You need to specify the values for all related connection properties manually.

  • Repository: The connection details stored centrally in Repository > Metadata will be reused by this component. You need to click the [...] button next to it and in the pop-up Repository Content dialog box, select the connection details to be reused, and all related connection properties will be automatically filled in.

JDBC Provider

Select the provider of the JDBC driver to be used.


Specify the IP address or hostname of the Azure SQL Data Warehouse to be used.


Specify the listening port number of the Azure SQL Data Warehouse to be used.


Enter the name of the Azure SQL Data Warehouse schema.


Specify the name of the Azure SQL Data Warehouse to be used.

Username and Password

Enter the user authentication data to access the Azure SQL Data Warehouse.

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 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 fields.

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

  • 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 schema to make changes to the schema.
Note: If you make changes, the schema automatically becomes built-in.
  • 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 window.

Table name

Specify the name of the table to be used.

Turn on identity insert

Select this check box to use your own sequence for the identity value of the inserted records (instead of having the SQL Server pick the next sequential value).

Query Type

Select the way the query will be set.

  • Built-in: Fill in manually the query statement or build it graphically using SQLBuilder.

  • Repository: Select the relevant query stored in the Repository. The Query field gets accordingly filled in.

Guess Query

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


Specify your database query paying particularly attention to properly sequence the fields in order to match the schema definition.

Specify a data source alias

Select this check box and in the Data source alias field displayed, specify the alias of a data source created on Talend Runtime side to use the shared connection pool defined in the data source configuration. This option works only when you deploy and run your Job in Talend Runtime.

This check box is not available when the Use an existing Connection check box is selected.

Die on error

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

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 connection.

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, encrypt=true;trustServerCertificate=false; hostNameInCertificate=*.database.windows.net;loginTimeout=30; for Azure SQL database connection.

Authenticate using Azure Active Directory

Select this option to use Azure Active Directory authentication when establishing the connection. See Azure AD Authentication for related information.

Note: This option is available only if you have installed the R2020-05 Studio Monthly update or a later one delivered by Talend. For more information, check with your administrator.

Propagate QUERY's recordset

Select this check box to insert the result of the query into a column of the current flow. Select this column from the use column list.

This option allows the component to have a different schema from that of the preceding component. Moreover, the column that holds the QUERY's recordset should be set to the type of Object and this component is usually followed by tParseRecordSet.

Use PreparedStatement

Select this check box if you want to query the database using a PreparedStatement. In the Set PreparedStatement Parameters table, define the parameters represented by "?" in the SQL instruction of the Query field in the Basic Settings tab.

  • Parameter Index: Enter the parameter position in the SQL instruction.

  • Parameter Type: Enter the parameter type.

  • Parameter Value: Enter the parameter value.

This option is very useful if you need to execute the same query several times. Performance levels are increased.

Commit every

Enter the number of rows to be completed before committing batches of rows together into the database. This option ensures transaction quality (but not rollback) and above all better performance on executions.

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


The error message generated by the component when an error occurs. This is an After variable and it returns a string.


The query statement being processed. This is a Flow variable and it returns a string.


Usage rule

This component offers the flexibility of the DB query and covers all possible SQL queries.

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 connection 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 settings and context variables, see Talend Studio User Guide.


Note that some features that are supported by other databases are not supported by Azure SQL Data Warehouse. For more information, see Unsupported table features.

Also note that when creating or deleting a table with this component, it is recommended to use the auto commit function by reusing the database connection created by a tAzureSynapseConnection component and selecting the Auto Commit check box on the Advanced settings view of the tAzureSynapseConnection component, instead of using a tAzureSynapseCommit component.
