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

The Standard tAccessBulkExec component belongs to the Databases family.

The component in this framework is available in all Talend products.

Basic settings

Property type

Either Built-in or Repository .

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

  • Built-in: No property data is stored centrally.
  • Repository: Select the repository file in which the properties are stored. The fields that follow are completed automatically using the data retrieved.

Table

Name of the table to be written. Note that only one table can be written at a time and that the table must exist already for the insert operation to succeed.

File Name

Browse to the delimited file to be loaded into your database.

Create directory if does not exist

Select this check box to have the directories specified in the File Name field created if the directories do not exist.

Append

Select this check box to append the data to the file.

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.

Since version 5.6, both the Built-In mode and the Repository mode are available in any of the Talend solutions.

  • Built-in: The schema is created and stored locally for this component only. Related topic: see Talend Studio User Guide.
  • Repository: The schema already exists and is stored in the Repository, hence can be reused. Related topic: see 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.

Advanced settings

Include header

Select this check box to include the column header.

Use text enclosure

Select this check box to enclose the text with characters. You can specify the character used to enclose the text in the Field enclosure field.

Encoding

Select the encoding from the list or select Custom and define it manually. This field is compulsory for DB data handling.

tStatCatcher Statistics

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

Usage

Usage rule

This component is to be used along with tAccessOutputBulk component. Used together, they can offer gains in performance while feeding an Access 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 Talend Studio User Guide.

Limitation

If you are using an ODBC driver, make sure that your JVM and ODBC versions match up: both 64-bit or 32-bit.
