Drop Oracle Table
نشر بواسطة : Obay Salah , November 28, 2024
Oracle DROP TABLE statement is used to remove or delete a table from the Oracle database
Syntax
DROP [schema_name].TABLE table_name [ CASCADE CONSTRAINTS ] [ PURGE ];
Parameters
schema_name: It specifies the name of the schema that owns the table
table_name: It specifies the name of the table which you want to remove from the Oracle database
CASCADE CONSTRAINTS: It is optional. If specified, it will drop all referential integrity constraints as well
PURGE: It is also optional. If specified, the table and its dependent objects are placed in the recycle bin and can?t be recovered
If there are referential integrity constraints on table_name and you do not specify the CASCADE CONSTRAINTS option, the DROP TABLE statement will return an error and Oracle will not drop the table
DROP TABLE Example
DROP TABLE customers;
This will drop the table named customers
DROP TABLE Example with PURGE parameter
DROP TABLE customers PURGE
This statement will drop the table called customers and issue a PURGE so that the space associated with the customers table is released and the customers table is not placed in recycle bin. So, it is not possible to recover that table if required.
