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

The Standard tIntervalMatch component belongs to the Data Quality 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 Repository. When you create a Spark Job, avoid the reserved word line when naming the fields.

 

Built-in: The schema will be 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 in various projects and job flowcharts. 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.

Search Column

Select the main flow column containing the values to be matched with a range of values

Column (LOOKUP)

Select the lookup flow column containing the values to be returned when the Join is ok.

Lookup Column (min) / Include the bound (min)

Select the column containing the minimum value of the range. Select the check box to include the minimum value of the range in the match.

Lookup Column (max) / Include the bound (max)

Select the column containing the maximum value of the range. Select the check box to include the maximum value of the range in the match.

Advanced settings

tStat Catcher Statistics

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

Global Variables

Global Variables

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.

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

Usage rule

This component handles flow of data therefore it requires input and output, hence is defined as an intermediary step.
