# tIntervalMatch Returns a value based on a Join relation. tIntervalMatch receives a main flow and aggregates it based on join to a lookup flow. Then it matches a specified value to a range of values and returns related information. This component is not shipped with your Talend Studio by default. You need to install it using the Feature Manager. For more information, see [Installing features using the Feature Manager](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/install-features-to-talend-studio). ## tIntervalMatch Standard properties 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 | Properties | Description | | --- | --- | | 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.
Built-in: The schema will be created and stored locally for this component only. For more information about a component schema in its Basic settings tab, see Basic settings tab.
Repository: The schema already exists and is stored in the Repository, hence can be reused in various projects and Job flowcharts. For more information about a component schema in its Basic settings tab, see Basic settings tab.
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.

when the Join is ok. | | Lookup Column (min) / Include the bound

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 checkbox is
cleared, if the component has this checkbox.

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.

and output, hence is defined as an intermediary step. | **Related concepts** * [Identifying server locations based on their IP addresses](https://help.qlik.com/talend/en-US/components/8.0/standardization/tintervalmatch-tfileinputdelimited-tlogrow-tlogrow-identifying-server-locations-based-on-their-ip-addresses-standard-component-this)
