SHOW TABLES DROPPED
Applies to: 
Databricks SQL Databricks Runtime 12.2 LTS and above
Important
This feature is in Public Preview.
This command lists all tables which have been dropped within the schema in Unity Catalog, but can still be undropped. Specifically, it lists all dropped tables within the retention period (default is 7 days). If the schema or catalog have been dropped, an error is raised. If no schema is specified then the tables are returned from the current schema.
The command will only list tables which the requester is able to UNDROP.
Consequently, metastore/catalog/schema owners have privileges to list all dropped tables within their respective securable ownership.
Users with table level ownership will only be able to view tables which they own within the input catalog/schema as long as they have the USE CATALOG privilege on the parent catalog and the USE SCHEMA privilege on the parent schema.
Syntax
SHOW TABLES DROPPED [ { FROM | IN } schema_name ] [ LIMIT maxResults ]
Parameters
-
Specifies schema name from which tables are to be listed. If not provided, uses the current schema. If the schema or catalog does not exist or has been dropped, a SCHEMA_NOT_FOUND error is raised.
maxResult
An integer literal limiting the number of tables returned.
