(SQL Server) Firebase DELETE - Removing Data

Uses the DELETE method to delete data. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

    --  This example requires the Chilkat API to have been previously unlocked.
    --  See Global Unlock Sample for sample code.

    --  This example assumes a JWT authentication token, if required, has been previously obtained.
    --  See Get Firebase Access Token from JSON Service Account Private Key for sample code.

    --  Load the previously obtained Firebase access token into a string.
