Databases/Sybase IQ

Basic settings

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 fields that follow are completed automatically using the data retrieved.

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

 

DB Version

Select the version of the Sybase IQ database to be used from the list, either Sybase IQ 12 or Sybase IQ 15.

  • For Sybase IQ 12, the file to be bulk-loaded must be located on the same machine as the Sybase IQ 12 server.

  • For Sybase IQ 15, the file to be bulk-loaded can be located on a remote machine. However, this means certain setup on the Sybase IQ 15 server. For details, see Sybase IQ client-side load support enhancements.

Note that the Sybase IQ 15 version is connected to via ODBC while the Sybase IQ 12 version is via JDBC, so the fields to be completed on the Basic settings view vary slightly between the alternative versions.

 

Use an 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 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.

For an example about how to share a database connection across Job levels, see Talend Studio User Guide.

This check box is available only when Sybase IQ 12 is selected from the DB Version drop-down list.

 

Host

Enter the database server IP address.

This field is available only when Sybase IQ 12 is selected from the DB Version drop-down list.

 

Port

Enter the listening port number of DB server.

This field is available only when Sybase IQ 12 is selected from the DB Version drop-down list.

 

Data Source

Select the type of the data source to be used and complete the corresponding DSN information in the field alongside. The available types are DSN and FILEDSN.

When the FILEDSN type is used, a [...] button appears next to the Data Source field to allow you to browse to the data source file of interest.

This list is available only when Sybase IQ 15 is selected from the DB Version drop-down list.

 

Database

Enter the name of the database.

 

Username and Password

Enter the DB user authentication data.

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.

 

Table

Enter the name of the table to be written. Note that only one table can be written at a time and that the table must exist for the insert operation to succeed.

 

Action on table

On the table defined, you can perform one of the following operations:

  • Default: No operation is carried out.

  • Drop and create table: The table is removed and created again.

  • Create table: The table does not exist and gets created.

  • Create table if does not exist: The table is created if it does not exist.

  • Drop table if exists and create: The table is removed if it already exists and created again.

  • Clear table: The table content is deleted.

  • Truncate table: The table content is deleted. You do not have the possibility to rollback the operation.

 

Local filename

Specify the path to the file to be loaded.

 

Schema and Edit schema

A schema is a row description, it defines the number of fields to be processed and passed on to the next component. The schema is either Built-In or stored remotely in the Repository.

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

Click Edit schema 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] window.

 

 

Built-In: You create and store the schema locally for this component only. Related topic: see Talend Studio User Guide.

 

 

Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs. Related topic: see Talend Studio User Guide.

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 Scenario 3: Reading data from MySQL databases through context-based dynamic connections and Scenario: 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.

Usage

This dedicated component offers performance and flexibility of Sybase IQ DB query handling.

Log4j

If you are using a subscription-based version of the Studio, the activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User Guide.

For more information on the log4j logging levels, see the Apache documentation at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html.

Limitation

As opposed to the Oracle dedicated bulk component, no action on data is possible using this Sybase dedicated component.

This component requires installation of its related jar files. For more information about the installation of these missing jar files, see the section describing how to configure the Studio of the Talend Installation and Upgrade Guide.

The jodbc.jar also needs to be installed separately in the Modules view of the Integration perspective in your studio. For details, see the section about external modules in the Talend Installation and Upgrade Guide.

Warning

For Sybase IQ 12, the database client/server should be installed on the same machine where the Studio is installed or where the Job using tSybaseIQBulkExec is deployed, so that the component functions properly.

For Sybase IQ 15, it is allowed that only the database client is installed on the same machine where the Studio is installed or where the Job using tSybaseIQBulkExec is deployed, so that the component functions properly. However, this means certain setup on the Sybase IQ 15 server. For details, see Sybase IQ client-side load support enhancements.
