The rows in heap-organized tables that are native to Oracle Database have row addresses called rowids. You can examine a rowid row address by querying the pseudocolumn ROWID. Values of this pseudocolumn are strings representing the address of each row. These strings have the data type ROWID. You can also create tables and clusters that contain actual columns having the ROWID data type. ()

As mentioned in the , ROWID is not supported by Snowflake. The following query displays an error in Snowflake since hr.employees do not contain a ROWID column.
