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.

MERGE: Updates and/or adds data to the table. Note that the options available for the MERGE operation are different to those available for the Insert, Update or Delete operations.

Note

Following global variables are available:

  • NB_LINE_INSERTED: Number of lines inserted during the Insert operation.

  • NB_LINE_UPDATED: Number of lines updated during the Update operation.

  • NB_LINE_DELETED: Number of lines deleted during the Delete operation.

  • NB_LINE_MERGED: Number of lines inserted and/or updated during the MERGE operation.

 

Schema and Edit schema

A schema is a row description, it defines the number of fields to be processed and passed on to the next component. The schema is either built-in or remotely stored in the Repository.

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.

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

 

 

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 can be reused. 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.

 

Use Merge Update (for MERGE)

Select this check box to update the data in the output table.

Column : Lists the columns in the entry flow.

Update : Select the check box which corresponds to the name of the column you want to update.

Use Merge Update Where Clause : Select this check box and enter the WHERE clause required to filter the data to be updated, if necessary.

Use Merge Update Delete Clause: Select this check box and enter the WHERE clause required to filter the data to be deleted and updated, if necessary.

 

Use Merge Insert (for MERGE)

Select this check box to insert the data in the table.

Column: Lists the entry flow columns.

Check All: Select the check box corresponding to the name of the column you want to insert.

Default Table Name

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

 

Default Schema Name

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

 

Use different table name

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

Advanced settings

Use Hint Options

Select this check box to activate the hint configuration area when you want to use a hint to optimize a query's execution. In this area, parameters are:

- HINT: specify the hint you need, using the syntax /*+ */.

- POSITION: specify where you put the hint in a SQL statement.

- SQL STMT: select the SQL statement you need to use.

 

tStatCatcher Statistics

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

tELTOracleOutput is to be used along with the tELTOracleInput and tELTOracleMap components. Note that the Output link to be used with these components must correspond strictly to the syntax of the table name.

Note

Note that the ELT components do not handle actual data flow but only schema information.

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.
