tPostgresqlBulkExec Standard properties

Select the desired database type from the list and click Apply.

Property type

Either Built-in or Repository

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 Retrieving table schemas.

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

Schema and Edit Schema

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

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.

This property is not available when the Use an existing connection check box in the Basic settings view is selected.

Action on data

Select the action to be performed on the table data:

Copy the OID for each row

Retrieve the ID item for each row.

Contains a header line with the names of each column in the file

Use local file for copy (for DB server 8.2 or newer)

(Enabled by default) Select this check box to copy files from the PostgreSQL client machine.

Set encoding and Encoding

Select the option to set a specific encoding. Select the encoding standard from the list, or select CUSTOM and define it manually.

tStatCatcher Statistics

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

Usage rule

This component is to be used along with tPostgresqlOutputBulk component. Used together, they can offer gains in performance while feeding a Postgresql database.

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.

The Dynamic settings table is available only when the Use an existing connection check box is selected in the Basic settings view. Once a dynamic parameter is defined, the Component List box in the Basic settings view becomes unusable.

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 Dynamic schema and Creating a context group and define context variables in it.
