With Oracle Spatial, we have the option of using sites like db<>fiddle and Oracle Live SQL to mock up SQL or data online...and share it...when troubleshooting code in forums (Esri Community, GIS SE, etc.).
That works great when using native datatypes like SDO_GEOMETRY. But when it comes to datatypes like SDE.ST_GEOMETRY, we're out of luck.
Could Esri provide an online playground that has the ST_GEOMETRY datatype (in Oracle)? Similar to what we have for Arcade, but also shareable.
