tParAccelOutputBulkExec Standard properties

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

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.

Host

Database server IP address.

Currently, only localhost, 127.0.0.1 or the exact IP address of the local machine is allowed for proper functioning. In other words, the database server must be installed on the same machine where the Studio is installed or where the Job using tParAccelOutputBulkExec is deployed.

Port

Listening port number of the DB server.

Database

Database name.

Schema

Exact name of the schema.

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 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 table: The table is removed and created again.

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

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

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

Clear table: The table content is deleted.

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.

For more information, see the related description of retrieving table schemas in Talend Studio User Guide.

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.

Copy mode

Select the copy mode you want to use from either:

Basic: Standard mode, without optimisation.

Parallel: Allows you to use several internal ParAccel APIs in order to optimise loading speed.

Filename

Name of the file to be generated and loaded.

Additional JDBC Parameters

Specify additional JDBC parameters for the database connection created.

File Type

Select the file type from the list.

Row separator

String (ex: "\n"on Unix) to distinguish rows.

Fields terminated by

Character, string or regular expression to separate fields.

Append

Select this check box to add the new rows at the end of the file.

Explicit IDs

The ID is already present in the file to be loaded or will be set by the database.

Remove Quotes

Select this check box to remove quotation marks from the file to be loaded.

Max. Errors

Type in the maximum number of errors before your Job stops.

Log file

Browse to or enter the access path to the log file in your directory.

Logging level

Select the information type you want to record in your log file.

tStat Catcher Statistics

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

Usage rule

This component covers all possible SQL database queries. It allows you to carry out actions on a table or on the data of a table in a ParAccel database. It enables you to create a reject flow, with a Row > Reject link filtering the data in error. For a usage example, see Retrieving data in error with a Reject link.

Limitation

The database server must be installed on the same machine where the Studio is installed or where the Job using tParAccelOutputBulkExec is deployed, so that the component functions properly.
