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

Function

Carries out the action on the table specified and inserts the data according to the output schema defined the ELT Mapper.

Purpose

Executes the SQL Insert, Update and Delete statement in the Mysql database

tELTSybaseOutput properties

Componant family

ELT/Map/Sybase

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.

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

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.

 

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.

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

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

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.

Log4j

If you are using a subscription-based version of the Studio, the activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User Guide.

For more information on the log4j logging levels, see the Apache documentation at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html.

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.
