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

## Basic settings

| Properties | Description |
| --- | --- |
| Field to split | Select an incoming field from the Field to<br>split list to split. |
| Ignore NULL as the source data | Select this check box to ignore the Null value in the source data.<br><br>Clear this check box to generate the Null records that correspond<br>to the Null value in the source data. |
| Field separator | Enter a character, a string, or a regular expression to separate<br>fields for the transferred data.<br><br>Information noteNote:<br><br>Since this component uses regex to split a filed and the regex<br>syntax uses special characters as operators, make sure to<br>precede the regex operator you use as a field separator by a<br>double backslash. For example, you have to use "\\\|" instead of<br>"\|". |
| Die on error | Clear the checkbox to skip any rows on error and complete the process for<br>error-free rows. When errors are skipped, you can collect the rows on error using a Row &gt; Reject link. |
| Schema and Edit<br>Schema | <ul> <li> <p>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 <kbd>line</kbd> when naming the            fields.</p> <p>Click <span>Edit        schema</span> to make changes to the schema. If the current schema is of the <span>Repository</span> type, three options are available:</p> <ul> <li> <p> <span>View schema</span>: choose this                option to view the schema only.</p> </li> <li> <p> <span>Change to built-in property</span>:                choose this option to change the schema to <span>Built-in</span> for local changes.</p> </li> <li> <p> <span>Update repository connection</span>:                choose this option to change the schema stored in the repository and decide whether                to propagate the changes to all the Jobs upon completion.</p> <p>If you just want to                propagate the changes to the current Job, you can select <span>No</span> upon completion and choose this schema metadata                again in the <span>Repository Content</span>                window.</p> </li> </ul> <p>Click <span>Sync        columns</span> to retrieve the schema from the previous component connected in the      Job.</p> </li> <li> <p> <span>Built-In</span>: You create and store the schema locally for this component                only.</p> </li> <li> <p> <span>Repository</span>: You have already created the schema and stored it in the                Repository. You can reuse it in various projects and Job designs.</p> </li> </ul> |

## Advanced settings

| Properties | Description |
| --- | --- |
| Advanced separator (for number) | Select this check box to change the separator used for numbers. By default, the thousands separator is a comma (*,*) and the decimal separator is a period (*.*). |
| Trim column | Select this check box to remove leading and trailing whitespace<br>from all columns. |
| Check each row structure against schema | Select this check box to check whether the total number of columns<br>in each row is consistent with the schema. If not consistent, an<br>error message will be displayed on the console. |
| Validate date | Select this check box to check the date format strictly against the input schema. |
| tStatCatcher Statistics | Select this check box to gather the processing metadata at the Job<br>level as well as at each component level. |

## Global Variables

| Variables | Description |
| --- | --- |
| Global Variables | ERROR\_MESSAGE: the error message generated by the<br>component when an error occurs. This is an After variable and it returns a string. This<br>variable functions only if the Die on error checkbox is<br>cleared, if the component has this checkbox.<br><br><br>NB\_LINE: the number<br>of rows read by an input component or transferred to an output component. This is an<br>After variable and it returns an integer.<br><br>A Flow variable functions during the execution of a component<br>while an After variable functions after the execution of the component.<br><br>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<br>it.<br><br>For more information about variables, see [Using contexts and variables](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/contexts-and-variables). |

## Usage

| Usage guidance | Description |
| --- | --- |
| **Usage rule** | This component handles flow of data therefore it requires input<br>and output components. It allows you to extract data from a<br>delimited field, using a Row &gt;<br>Main link, and enables you to<br>create a reject flow filtering data which type does not match the<br>defined type. |
