tReplace Standard properties

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

The Standard tReplace component belongs to the Processing family.

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

Basic settings

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.

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.

Two read-only columns, Value and Match are added to the output schema automatically.


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.

Simple Mode Search / Replace

Click the button to add as many conditions as needed. The conditions are performed one after the other for each row.

Input column: Select the column of the schema the search & replace is to be operated on

Search: Type in the value to search in the input column

Replace with: Type in the substitution value.

Whole word: Select this check box if the searched value is to be considered as whole.

Case sensitive: Select this check box to care about the case.

Note that you cannot use regular expression in these columns.

Use advanced mode

Select this check box when the operation you want to perform cannot be carried out through the simple mode. In the text field, type in the regular expression as required.

Advanced settings

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

Global Variables

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.

NB_LINE: the number of rows read by an input component or transferred to an output component. This is an After variable and it returns an integer.

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 more information about variables, see Using contexts and variables.


Usage rule

This component is not startable as it requires an input flow. And it requires an output component.
