Select a type of database from the list and click
Apply.

Property Type

Select the way the connection details
will be set.

• Built-In: The connection details will be set
  locally for this component. You need to specify the values for all
  related connection properties manually.

• Repository: The connection details stored
  centrally in Repository > Metadata will be reused by this component. You need to click
  the […] button next to it and in the pop-up
  Repository Content dialog box, select the
  connection details to be reused, and all related connection
  properties will be automatically filled in.

This property is not available when other connection component is selected
from the Connection Component drop-down list.

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.

Connection Component

Select the component that opens the database connection to be reused by this
component.

JDBC URL

The JDBC URL of the database to be used. For
example, the JDBC URL for the Amazon Redshift database is jdbc:redshift://endpoint:port/database.

Drivers

Complete this table to load the driver JARs needed. To do
this, click the [+] button under the table to add
as many rows as needed, each row for a driver JAR, then select the cell and click the
[…] button at the right side of the cell to
open the Module dialog box from which you can select the driver JAR
to be used. For example, the driver jar RedshiftJDBC41-1.1.13.1013.jar for the Redshift database.

For more information, see Importing a database driver.

Driver Class

Enter the class name for the specified driver between double
quotation marks. For example, for the RedshiftJDBC41-1.1.13.1013.jar driver, the name to be entered is
com.amazon.redshift.jdbc41.Driver.

Use Id and Password

The database 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

The name of the table into
which data will be written.

Data Action

Select an action to be performed on data of the table defined.

• 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 in the
  index pool. 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 in the index pool, a new record would be
  inserted.

• Delete: Remove entries corresponding to
  the input flow.

Clear data in table

Select this check box to clear data in the table before performing the
action defined.

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.

• 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).

• 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.

Guess Schema

Click this button to generate schema columns based on the settings of database table
columns.

Die on error

Select the check box to stop the execution of the Job when an error
occurs.

Clear the check box to skip any rows on error and complete the
process for error-free rows.

When errors are skipped, you can collect the rows on error
using a Row > Reject connection.

Specify a data source alias

Select this check box and in the
Data source alias field displayed, specify the alias of
a data source created on Talend Runtime side to use
the shared connection pool defined in the data source configuration. This option
works only when you deploy and run your Job in Talend Runtime.

If you use the component’s own DB configuration, your data source
connection will be closed at the end of the component. To prevent this from
happening, use a shared DB connection with the data source alias specified.

This property is not available when other connection component is selected from
the Connection Component drop-down list.

Commit every

Specify the number of rows to be processed before committing
batches of rows together into the database.

This option ensures transaction quality (but not rollback) and, above all, better
performance at executions.

Additional Columns

This option allows you to call SQL functions to perform actions on columns, which are
not insert, update or delete actions, or actions that require particular preprocessing.
It is not offered if you create (with or without drop) the database table.

• Name: The name of the schema column to be inserted, or the
  name of the schema column used to replace an existing column.

• SQL expression: The SQL statement to be executed in order to
  insert or replace relevant column.

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

• Reference column: The name of the reference column that can
  be used to locate the new column to be inserted or that will be replaced.

Use field options

Select this check box and in the Fields options table
displayed, select the check box for the corresponding column to customize a
request, particularly if multiple actions are being carried out on the
data.

• Key in update: Select the check box for the
  corresponding column based on which data is updated.
• Key in delete: Select the check box for the
  corresponding column based on which data is deleted.

• Updatable: Select the check box if data in the
  corresponding column can be updated.

• Insertable: Select the check box if data in
  the corresponding column can be inserted.

Debug query mode

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

Use Batch

Select this check box to activate the batch mode for data
processing, and in the Batch Size field displayed, specify the
number of records to be processed in each batch.

tStatCatcher Statistics

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

Enable parallel execution

Select this check box to perform high-speed data processing by treating
multiple data flows simultaneously. This feature depends on the database or
the application ability to handle multiple inserts in parallel as well as
the number of CPU affected. With this check box selected, you need to
specify the number of parallel executions desired in the Number
of parallel executions field displayed.

ERROR_MESSAGE

The error message generated by the component when an error occurs. This is an After
variable and it returns a string.

NB_LINE

The number of rows processed. 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_UPDATED

The number of rows updated. 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 being processed. This is a Flow variable and it returns a
string.

Usage rule

This component offers the flexibility benefit of the
database 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 JDBC 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.

Dynamic settings

Click the [+] button to add a row in the table
and fill the Code field with a context
variable to choose your database connection dynamically from multiple
connections planned in your Job. This feature is useful when you need to
access database tables having the same data structure but in different
databases, especially when you are working in an environment where you
cannot change your Job settings, for example, when your Job has to be
deployed and executed independent of Talend Studio.

For examples on using dynamic parameters, see Reading data from databases through context-based dynamic connections and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic
settings and context variables, see Talend Studio
User Guide.
