tSybaseOutputBulkExec – Docs for ESB 7.x

tSybaseOutputBulkExec

Gains in performance during Insert operations to a Sybase database.

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.

tSybaseOutputBulkExec Standard properties

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

The Standard
tSybaseOutputBulkExec component belongs to the Databases family.

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

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

Database

Select a type of database from the list and click
Apply.

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.

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
.

DB Version

Select the version of the Sybase database to be used from the
drop-down list.

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. 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.

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.

You can find more details about how to
verify default values in retrieved schema in 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

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 used in the
former component and x09 used in the latter.

DB Row terminator

String (ex: ”
“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.

Usage

Usage rule

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

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.

Limitation

This component requires installation of its related jar files.

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.
