tELTSybaseMap – Docs for ESB 6.x

tELTSybaseMap

Builds the SQL SELECT statement using the table schema(s) provided by one or more
tELTSybaseInput components.

The three ELT Sybase components are closely related, in terms of their
operating conditions. These components should be used to handle Sybase database table
schemas to generate SQL statements, including clauses, which are to be executed in the
database output table defined.

tELTSybaseMap Standard properties

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

The Standard
tELTSybaseMap component belongs to the
ELT family.

The component in this framework is generally available.

Basic settings

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
.

ELT Sybase Map Editor

The ELT Map editor allows you to define the output schema
and make a graphical build of the SQL statement to be executed. The
column names of schema can be different from the column names in the
database.

Style link

Select the way in which links are displayed.

Auto: By default, the links
between the input and output schemas and the Web service parameters are
in the form of curves.

Bezier curve: Links between the
schema and the Web service parameters are in the form of curve.

Line: Links between the schema
and the Web service parameters are in the form of straight lines.

This option slightly optimizes performance.

Property type

Can be either Built-in or Repository.

 

Built-in : No property data is
stored centrally.

 

Repository : Select the
Repository file where the component properties are stored. The following
fields are pre-filled using collected data.

DB Version

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

Host

Database server IP address.

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.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at a Job
level as well as at component level.

Global Variables

Global Variables

ERROR_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This
variable functions only if the Die on error check box is
cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable
functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl +
Space
to access the variable list and choose the variable to use from it.

For further information about variables, see
Talend Studio

User Guide.

Usage

Usage rule

tELTSybaseMap is intended for use
with tELTSybaseInput and tELTSybaseOutput. Note that the Output link
to be used with these components must correspond strictly to the syntax
of the table name.

Note:

The ELT components only handle schema information. They do not
handle actual data flow.

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: Reading data from 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
.

Limitation

This component requires installation of its related jar files.
