Component Family

File/Input

 

Function

tFileInputLDIF reads a given LDIF file row by row.

Purpose

tFileInputLDIF opens a file, reads it row by row, et gives the full rows to the next component as defined in the schema, using a Row connection.

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 where the properties are stored. The fields that follow are completed automatically using the data retrieved.

 

File Name

Name of the file and/or variable to be processed.

For further information about how to define and use a variable in a Job, see Talend Studio User Guide.

 

add operation as prefix when the entry is modify type

Select this check box to display the operation mode.

 

Value separator

Type in the separator required for parsing data in the given file. By default, the separator used is " ,".

 

Die on error

Select this check box to stop the execution of the Job when an error occurs. Clear the check box to skip the row on error and complete the process for error-free rows. If needed, you can collect the rows on error using a Row > Reject link.

 

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.

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

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

Encoding

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

 

Use field options (for Base64 decode checked)

Select this check box to specify the Base64-encoded columns of the input flow. Once selected, this check box activates the Decode Base64 encoding values table to enable you to precise the columns to be decoded from Base64.

Note

The data type of the columns to be handled by this check box is byte[] that you define in the input schema editor.

 

tStatCatcher Statistics

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

Global Variables

NB_LINE: the number of rows processed. This is an After variable and it returns an integer.

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

Usage

Use this component to read full rows in a voluminous LDIF file. This component enables you to create a data flow, using a Row > Main link, and to create a reject flow with a Row > Reject link filtering the data which type does not match the defined type. For an example of usage, see Scenario 2: Extracting erroneous XML data via a reject flow from tFileInputXML.

Log4j

If you are using a subscription-based version of the Studio, the activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User Guide.

For more information on the log4j logging levels, see the Apache documentation at http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html.
