UNCACHE TABLE
Applies to: 
Databricks Runtime
Removes the entries and associated data from the in-memory and/or on-disk cache for a given
table or view in Apache Spark cache. The underlying entries should already have been brought to cache by
previous CACHE TABLE operation. UNCACHE TABLE on a non-existent table throws an exception if IF EXISTS is not specified.
Syntax
UNCACHE TABLE [ IF EXISTS ] table_name
See Disk cache vs. Spark cache for the differences between disk caching and the Apache Spark cache.
Parameters

Identifies the Delta table or view to cache. The name must not include a temporal specification or options specification.
