DELETE

Synopsis

DELETE FROM table_name [ WHERE condition ]

Description

Delete rows from a table. If the WHERE clause is specified, only the matching rows are deleted. Otherwise, all rows from the table are deleted.

Examples

Delete all line items shipped by air:

DELETE FROM lineitem WHERE shipmode = 'AIR';

Delete all line items for low priority orders:

DELETE FROM lineitem
WHERE orderkey IN (SELECT orderkey FROM orders WHERE priority = 'LOW');

Delete all orders:

DELETE FROM orders;

Limitations

Some connectors have limited or no support for DELETE.

For example, to Hive connector, the behavior is different for transactional table and non-transactional table.

For transactional table, you can delete any row by where condition. However, for non-transactional table, DELETE is only supported if the WHERE clause matches entire partitions.

See connector documentation for more details.
