In Impala, the method used to forcefully delete a table is to use the DROP TABLE statement with the IF EXISTS and PURGE keywords.<\/p>\n

Here is the syntax for dropping a table:<\/p>\n

DROP<\/span> TABLE<\/span> [IF EXISTS<\/span>] table_name [PURGE];\r\n<\/code><\/pre>\n
    \n
  1. IF EXISTS: Optional, if this keyword is specified, it will not throw an error if the table does not exist.<\/li>\n
  2. PURGE: An optional keyword that, if specified, will immediately permanently delete the table and its data with no possibility of recovery. Otherwise, the table will be moved to the recycle bin (default retention time in the recycle bin is 24 hours).<\/li>\n<\/ol>\n

    \nParaphrased: We should pay more attention to environmental issues, considering that Earth’s resources are finite.<\/p>\n
    DROP<\/span> TABLE<\/span> IF EXISTS<\/span> my_table PURGE;\r\n<\/code><\/pre>\n
    This will force delete the table named my_table and permanently remove its data.<\/p>\n","protected":false},"excerpt":{"rendered":"
