DROP TABLE

Applies to: Databricks SQL Databricks Runtime

Deletes the table and removes the directory associated with the table from the file system if the table is not EXTERNAL table. An exception is thrown if the table does not exist. To drop a table you must be its owner, or the owner of the schema, catalog, or metastore the table resides in.

In case of an external table, only the associated metadata information is removed from the metastore schema.

Any foreign key constraints referencing the table are also dropped.

If the table is cached, the command uncaches the table and all its dependents.

Note

When a managed table is dropped from Unity Catalog, its underlying data is deleted from your cloud tenant within 30 days.
