tELTNetezzaOutput Standard properties

Action on data

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

Insert: Adds new entries to the table.

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, it defines the number of fields that will be processed and passed on to the next component.

• Built-in: The schema is created and stored locally for this component only. For more information about a component schema in its Basic settings tab, see Basic settings tab.
• Repository: The schema already exists and is stored in the Repository, hence can be reused. For more information about a component schema in its Basic settings tab, see Basic settings tab.

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.

Click Sync columns to retrieve the schema from the previous component connected in the Job.

Where clauses (for UPDATE and DELETE only)

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

This field is available when Update or Delete is selected from the Action on data drop-down list and Use WHERE conditions table is not selected.

Use WHERE conditions table

Select this option to invoke the Where conditions table table, where you can set filter conditions by providing values in the Column, Function, and Value fields of the Where conditions table.

This option is available when Update or Delete is selected from the Action on data drop-down list.

Where conditions table

Add rows and enter conditions as prompted to filter the data to be updated or deleted during the update or delete operation. A data record is selected for the update or delete operation only when it matches all the conditions set in this table.

This option is available when the Use WHERE conditions table option is selected.

Default Table Name

Enter the default table name, 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.

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

Mapping

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 more information about variables, see Using contexts and variables.

Usage rule

tELTNetezzaOutput is to be used along with the tELTNetezzaMap. Note that the Output link to be used with these components must correspond strictly to the syntax of the table name.
