tELTSybaseOutput – Docs for ESB 7.x

tELTSybaseOutput

Performs the action (insert, update or delete) on data in the specified Sybase
table through the SQL statement generated by the tELTSybaseMap
component.

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.

tELTSybaseOutput Standard properties

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

The Standard
tELTSybaseOutput component belongs to the
ELT family.

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

Basic settings

Action on data

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

Insert: Add new entries to the table. If duplicates are
found, the Job stops.

Update: Updates entries in the table.

Delete: Deletes the entries which
correspond to the entry flow.

Schema and Edit
schema

A schema is a row description, that is to say, it defines the
number and nature of the fields to be processed and passed on to the next
component. The schema is either Built-in (local) or stored remotely in the Repository
. The Schema defined is then passed on to the ELT Mapper for inclusion in
the Insert SQL statement.

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: The schema is created and
stored locally for this component only. Related topic: see
Talend Studio User Guide
.

 

Repository: The schema already exists
and is stored in the Repository. Hence, it can be re-used for other projects
and Jobs. Related topic: see
Talend Studio User Guide
.

Where clauses for (for UPDATE and DELETE
only
)

Enter a clause to filter the data to be updated or deleted
during the update or delete operations.

Default Table Name

Enter a default name for the table, between double quotation
marks.

Note that the table must exist already. If it
does not exist, you can use tCreateTable to create one
first. For more information about tCreateTable, see tCreateTable.

Default Schema Name

Enter a default name for the Sybase schema, between double
quotation marks.

Table name from connection name is
variable

Select this check box when the name of the connection to this
component is set to a variable, such as a context variable.

Use different table name

Select this check box to enter a different output table name,
between double quotation marks, in the Table
name
field which appears.

Mapping

Specify the metadata mapping file
for the database to be used. The metadata mapping file is used for the data
type conversion between database and Java. For more information about the
metadata mapping, see the related documentation for Type mapping.

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

NB_LINE: the number of rows read by an input component or
transferred to an output component. This is an After variable and it returns an
integer.

NB_LINE_INSERTED: the number of rows inserted. This is an
After variable and it returns an integer.

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

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

Note:

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

Limitation

This component requires installation of its related jar files.
