#2 Use the sxc data API to create/edit/delete data
The samples can differ based on your Razor base class or if you're running an old version.
Selected: Typed (2sxc 16+) Switch to Dynamic (Razor14 or below)

Use the sxc data API to create/edit/delete data

This page uses the sxc data API to create data for the backend.

In this tutorial you'll learn how to:

  • Create data using the .create(...) method
  • Update data using the .update(...) method
  • Delete data using the .delete(...) method

Look at the content below to see the effect.

Name Birth date Poems Actions
SuperPoet 602 1/1/2021 70
SuperPoet 31 1/1/2021 81
SuperPoet 314 1/1/2021 89
SuperPoet 698 1/1/2021 861
