tSybaseOutputBulkExec properties

The tSybaseOutputBulk and tSybaseBulkExec components are generally used together as parts of a two step process. In the first step, an output file is generated. In the second step, this file is used in the INSERT operation used to feed a database. These two steps are fused together in the tSybaseOutputBulkExec component.

Component family

Databases/Sybase

 

Function

Executes the Insert action on the data provided.

Purpose

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

Basic settings

Property type

Either Built-in or Repository.

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

 

 

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.

 

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.

 

Server

Database server IP address

Currently, only localhost, 127.0.0.1 or the exact IP address of the local machine is allowed for proper functioning. In other words, the database server must be installed on the same machine where the Studio is installed or where the Job using tSybaseOutputBulkExec is deployed.

 

Port

Listening port number of DB server.

 

Database

Name of the database

 

Username and Password

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.

 

Bcp utility

Name of the utility to be used to copy data over to the Sybase server.

 

Batch row number

Number of lines in each processed batch.

 

Table

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:

None: No operation is carried out.

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

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

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

Clear a table: The table content is deleted.

 

File Name

Name of the file to be generated and loaded.

Warning

This file is generated on the machine specified by the URI in the Server field so it should be on the same machine as the database server.

 

Append

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 https://help.talend.com/display/KB/Verifying+default+values+in+a+retrieved+schema.

  

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

Use an interface file

Select this check box to specify an interface file in the field Interface file.

 

Additional JDBC parameters

Specify additional connection properties in the existing DB connection, to allow specific character set support. E.G.: CHARSET=KANJISJIS_OS to get support of Japanese characters.

 

Action on data

On the data of the table defined, you can perform:

Bulk Insert: Add multiple entries to the table. If duplicates are found, job stops.

Bulk Update: Make simultaneous changes to multiple entries.

 

Field terminator

Character, string or regular expression to separate fields.

Warning

As a combination of tSybaseOutputBulk and tSybaseBulkExec, 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 tSybaseBulkExec together to replace tSybaseOutputBulkExec, with \t used in the former component and \x09 used in the latter.

 

DB Row terminator

String (ex: "\n"on Unix) to distinguish rows in the DB.

 

First row NO. of file

Type in the number of the file row where the action should start at.

 

FILE Row terminator

Character, string or regular expression to separate fields in a file.

 

Include Head

Select this heck box to include the column header.

 

Encoding

Regarding the source data, select the appropriate encoding from the list or select Custom and define it manually. This field is compulsory for DB data handling.

 

Sybase encoding type

Select the Sybase-specific encoding type for the data to be processed. This encoding type allows tSybaseOutputBulkExec to properly generate the Sybase Bulk command.

 

Output

Select the type of output for the standard output of the Sybase database:

to console,

to global variable.

 

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 database server/client must be installed on the same machine where the Studio is installed or where the Job using tSybaseOutputBulkExec is deployed, so that the component functions properly.
