Function

tSybaseIQOutputBulkExec executes the Insert action on the data provided.

Purpose

As a dedicated component, it allows gains in performance during Insert operations to a Sybase IQ database.

tSybaseIQOutputBulkExec properties

Component family

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.

 

Filename

Enter the name of the file to be generated and loaded.

 

Append the file

Select this check box to add the new rows at the end of the records.

 

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. 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.

 

 

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.

When the schema to be reused has default values that are integers or functions, ensure that these default values are not enclosed within quotation marks. If they are, you must remove the quotation marks manually.

For more details, see the article Verifying default values in a retrieved schema on Talend Help Center (https://help.talend.com).

 

 

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.

Advanced settings

Additional JDBC Parameters

Specify additional connection properties in the existing DB connection, to allow specific character set support.

 

Fields terminated by

Enter the character, string or regular expression used to separate fields.

Warning

As a combination of tSybaseOutputBulk and tSybaseIQBulkExec, this component does not allow the use of Sybase-oriented row/field separators, such as \x09. To achieve the desired effect (for example, displaying fields in the tabular form), you need to use tSybaseOutputBulk and tSybaseIQBulkExec together to replace tSybaseIQOutputBulkExec, with \t used in the former component and \x09 used in the latter.

 

Lines terminated by

Enter the character or sequence of characters used to separate lines.

 

Use enclosed quotes

Select this check box to use data enclosure characters.

 

Include Head

Select this heck box to include the column header.

 

Blank as null

Select this check box to store the input zero-length varchars as NULLs instead of blanks in the database during the load operation.

 

Encoding

Select the encoding type from the list or select Custom and define it manually. This field is compulsory for DB data handling.

 

tStatCatcher Statistics

Select this check box to collect log data at the component level.

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 component is mainly used when no particular transformation is required on the data to be loaded onto the database.

Limitation

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 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 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 tSybaseIQOutputBulkExec 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 tSybaseIQOutputBulkExec 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.

Scenario: Bulk-loading data to a Sybase IQ 12 database

This scenario describes a Job that writes data generated by a tRowGenerator component into a file and then bulk-loads the data from the file to a Sybase IQ 12 database.

Adding and linking the components

  1. Create a new Job and add a tRowGenerator component and a tSybaseIQOutputBulkExec component by typing their names in the design workspace or dropping them from the Palette.

  2. Link the tRowGenerator component to the tSybaseIQOutputBulkExec component using a Row > Main connection.

Configuring the components

  1. Double-click the tRowGenerator component to open its RowGenerator Editor.

  2. Click the [+] button to add two columns and set their properties:

    • id, Integer type, using Numeric.sequence(String,int,int) from the Functions list to generate sequence numbers.

    • name, String type, using TalendDataGenerator.getFirstName() from the Functions list to generate random first names.

  3. In the Number of Rows for RowGenerator field, enter the number of rows to be generated. In this example, keep the default value 100.

  4. Click OK to close the editor and in the pop-up dialog box click Yes to propagate the schema to the next component.

  5. Double-click the tSybaseIQOutputBulkExec component to open its Basic settings view.

  6. In the Host, Port, Database, Username and Password fields, enter the information required to access the Sybase IQ 12 database.

  7. In the Table field, enter the name of the table into which the data will be writen. In this example, it is staff.

  8. In the Action on table list, select Create table if not exists.

  9. In the Filename field, enter the full path of the file to hold the data.

Saving and executing the Job

  1. Press Ctrl+S to save the Job.

  2. Press F6 to run the Job.

  3. In the Sybase Central console, open the table staff to check the data:

    As shown above, the table is created with data inserted.
