The tAccessOutputBulk and tAccessBulkExec components are generally used together to output data to a delimited file and then to perform various actions on the file in an Access database, in a two step process. These two steps are fused together in tAccessOutputBulkExec.

Component family

Databases/Access

 

Function

The tAccessOutputBulkExec component executes an Insert action on the data provided.

Purpose

As a dedicated component, it improves performance during Insert operations in an Access database.

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 stored centrally.

 

 

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

 

Use an existing connection

Select this check box and in the Component List click the relevant connection component to reuse the connection details you already defined.

Note

When a Job contains the parent Job and the child Job, if you need to share an existing connection between the two levels, for example, to share the connection created by the parent Job with the child Job, you have to:

  1. In the parent level, register the database connection to be shared in the Basic settings view of the connection component which creates that very database connection.

  2. In the child level, use a dedicated connection component to read that registered database connection.

For an example about how to share a database connection across Job levels, see Talend Studio User Guide.

 

DB Version

Select the version of Access that you are using.

 

DB name

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.

 

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 already exist.

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

Clear table: The table content is deleted.

 

Table

Name of the table to be written.

Note

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

 

FileName

Name of the file to be processed.

Related topic: see Talend Studio User Guide.

 

Action on data

On the data of the table defined, you can perform:

Insert: Add new entries to the table.

 

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: You create and store the schema locally for this component only. Related topic: see Talend Studio User Guide.

 

 

Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs. Related topic: see Talend Studio User Guide.

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 details, see https://help.talend.com/display/KB/Verifying+default+values+in+a+retrieved+schema.

  

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.

 

Create directory if not exists

Select this check box to create the as yet non existant file directory specified in the File name field.

 

Append

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

Advanced settings

Additional JDBC parameters

Specify additional connection properties for the DB connection you are creating. This option is not available if you have selected the Use an existing connection check box in the Basic settings.

Note

You can press Ctrl+Space to access a list of predefined global variables.

 

Include header

Select this check box to include the column header to the file.

 

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 the log data at the component level.

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 Scenario 3: Reading data from MySQL databases through context-based dynamic connections and Scenario: 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.

Usage

This component is mainly used when no particular transformation is required on the data to be loaded in the database.

Limitation

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