# tSplitRow Splits one input row into several output rows. ## tSplitRow Standard properties These properties are used to configure tSplitRow running in the Standard Job framework. The Standard tSplitRow component belongs to the Processing 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 to be processed and passed on to the next component. The schema is either Built-in or stored remotely in the Repository.

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.
Click Sync columns to retrieve the schema from the previous component connected in the Job.
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.
