tSasOutput

Executes the action defined on the table and/or on the data contained in the table,
based on the incoming flow from the preceding component in the Job.

Warning:

Before being able to benefit from all functional objectives of the SAS
components, make sure to install the following three modules: sas.core.jar,
sas.intrnet.javatools.jar and sas.svc.connection.jar in the path lib > java in
your
Talend Studio
 directory. You can later verify, if
needed whether the modules are successfully installed through the Modules view of
the Studio.

tSasOutput writes, updates, makes
changes or suppresses entries in a data­base.

tSasOutput Standard properties

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

The Standard
tSasOutput component belongs to the Databases 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.

SAS URL

Enter the URL to connect to the desired DB.

Driver JAR

In the drop down list, select a desired available driver, or
download one from a local directory through clicking the three-dot
button.

Class Name

Type in the Class name to be pointed to in the driver.

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.

Table

Name of the table to read.

Action on data

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

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

Update: Make changes to existing
entries

Insert or update: Insert a new record. If
the record with the given reference already exists, an update would be made.

Update or insert: Update the record with the
given reference. If the record does not exist, a new record would be inserted.

Delete: Remove entries
corresponding to the input flow.

Warning:

It is necessary to specify at least one
column as a primary key on which the Update and Delete operations are based. You can do that
by clicking Edit Schema and
selecting the check box(es) next to the column(s) you want
to set as primary key(s). For an advanced use, click the
Advanced settings view
where you can simultaneously define primary keys for the
Update and Delete operations. To do that:
Select the Use field
options check box and then in the Key in update column, select the
check boxes next to the column names you want to use as a
base for the Update operation. Do the same in the Key in delete column for the
Delete operation.

Clear data in table

Select this check box to delete data in the selected table before
any operation.

Schema and Edit
Schema

A schema is a row description. It defines the number of fields (columns) to
be processed and passed on to the next component. The schema is either Built-In or stored remotely in the Repository.

 

Built-In: You create and store the
schema locally for this component only. Related topic: see
Talend Studio

User Guide.

 

Repository: You have already created
the schema and stored it in the Repository. You can reuse it in various projects and
Job designs. Related topic: see
Talend Studio

User Guide.

When the schema to be reused has default values that are integers or
functions, ensure that these default values are not enclosed within quotation marks. If
they are, you must remove the quotation marks manually.

You can find more details about how to verify default
values in retrieved schema in Talend Help Center (https://help.talend.com).

 

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.

Die on error

This check box is selected by default. Clear the check box to skip
the row on error and complete the process for error-free rows. If
needed, you can retrieve the rows on error via a Row > Rejects link.

Advanced settings

Commit every

Enter the number of rows to be completed before committing batches
of rows together into the DB. This option ensures transaction
quality (but not rollback) and, above all, better performance at
execution.

Additional Columns

This option is not offered if you create (with or without drop)
the DB table. This option allows you to call SQL functions to
perform actions on columns, which are not insert, nor update or
delete actions, or action that require particular
preprocessing.

 

Name: Type in the name of the
schema column to be altered or inserted as a new column.

 

SQL expression: Type in the SQL
statement to be executed in order to alter or insert the relevant
column data.

 

Position: Select Before, Replace or After
following the action to be performed on the reference column.

 

Reference column: Type in a
column of reference that the tSasOutput
can use to place or replace the new or altered
column.

Use field options

Select this check box to customize a request, especially when
there is double action on data.

Enable debug mode

Select this check box to display each step during processing
entries in a database.

tStatCatcher Statistics

Select this check box to collect log data at the component
level.

Enable parallel execution

Select this check box to perform high-speed data processing, by treating multiple data flows
simultaneously. Note that this feature depends on the database or the application ability to
handle multiple inserts in parallel as well as the number of CPU affected. In the Number of parallel executions field, either:

  • Enter the number of parallel executions desired.

  • Press Ctrl + Space and select the appropriate
    context variable from the list. For further information, see
    Talend Studio
    User Guide    .

Note that when parallel execution is enabled, it is not possible to use global variables to
retrieve return values in a subjob.

  • The Action on table
    field is not available with the parallelization function. Therefore, you
    must use a tCreateTable component if you
    want to create a table.

  • When parallel execution is enabled, it is not possible to use global
    variables to retrieve return values in a subjob.

Global Variables

Global Variables 

NB_LINE: the number of rows processed. This is an After
variable and it returns an integer.

NB_LINE_UPDATED: the number of rows updated. 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.

NB_LINE_DELETED: the number of rows deleted. This is an
After variable and it returns an integer.

NB_LINE_REJECTED: the number of rows rejected. 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

This component offers the flexibility benefit of the DB query and
covers all of the SQL queries possible.

This component must be used as an output component. It allows you
to carry out actions on a table or on the data of a table in a SAS
database. It also allows you to create a reject flow using a
Row > Rejects link to filter
data in error. For an example of tMySQLOutput in use, see Scenario: Retrieving data in error with a Reject link.
Limitation

Due to license incompatibility, one or more JARs required to use this component are not
provided. You can install the missing JARs for this particular component by clicking the
Install button on the Component tab view. You can also find out and add all missing JARs easily on the
Modules tab in the
Integration
 perspective of your
studio. You can find more details about how to install external modules in Talend Help Center (https://help.talend.com).
