  2. Delete Data

To delete data on Polybase, you must implement a function on your collection that calls selfdestruct(). By convention, this should be a function called del().

The following provides an example of a delete function that only allows the owner of the record to delete it.

collection Place {
  country: string;
  owner: id;

  constructor (id: string) {
    this.id = id;
    this.owner = ctx.publicKey.toHex();

  del () {
    if (owner != ctx.auth) {
      throw error();
