Property type

Either Built-in or
Repository
.

Built-in: No property data stored
centrally.

Repository: Select the repository
file in which the properties are stored. The fields that follow are
completed automatically using the data retrieved.

Click this icon to open a database connection wizard and store the
database connection parameters you set in the component Basic settings view.

For more information about setting up and storing database
connection parameters, see
Talend Studio User Guide.

Running Mode

Select on the list the Server Mode corresponding to your DB
setupamong the four propositions :

HSQLDb Server, HSQLDb WebServer, HSQLDb In Process Persistent, HSQLDb In Memory.

Use TLS/SSL sockets

Select this check box to enable the secured mode if
required.

Host

Database server IP address

Port

Listening port number of DB server.

Database

Name of the database

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.

DB path

Specify the directory to the database you want to connect to. This
field is available only to the HSQLDb In
Process Persistent running mode.

Db name

Enter the database name that you want to connect to. This field is
available only to the HSQLDb In Process
Persistent running mode and the HSQLDb In Memory running mode.

Table

Name of the table to be written. Note that only one table can be
written at a time

Action on table

On the table defined, you can perform one of the following
operations:

None: No operation is carried
out.

Drop and create a table: The table
is removed and created again.

Create a table: The table does not
exist and gets created.

Create a table if not exists: The
table is created if it does not exist.

Drop a table if exists and create:
The table is removed if it already exists and created again.

Clear a table: The table content is
deleted.

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.

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. When you create a Spark
Job, avoid the reserved word line when naming the
fields.

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: You create and store the schema locally for this component
only.

Repository: You have already created the schema and stored it in the
Repository. You can reuse it in various projects and Job designs.

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).

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.

Additional JDBC parameters

Specify additional connection properties for the DB connection you
are creating. When the running mode is HSQLDb
In Process Persistent , you can set the connection
property ifexists=true to allow connection to an
existing database only and avoid creating a new database.

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 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 tDBOutput 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.

Debug query mode

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

tStat
Catcher Statistics

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

Enable parallel execution

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

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_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.

QUERY: the query statement processed. This is an After
variable and it returns a string.

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.

A Flow variable functions during the execution of a component while an After variable
functions after the execution of the component.

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 MySQL
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 Retrieving data in error with a Reject link.

Connections

Outgoing links (from this component to another):

Row: Main; Reject

Trigger: Run if; On Component Ok;
On Component Error; On Subjob Ok; On Subjob Error.

Incoming links (from one component to this one):

Row: Main;

Trigger: Run if; On Component Ok;
On Component Error; On Subjob Ok; On Subjob Error.

Talend Studio User
Guide.
