How do you delete the data in a database table in Oracl…
One way to clear the data in an Oracle database table is by using the following methods:
- Use the DELETE statement:
- Remove all records from the table.
- This will delete all data in the table, but will preserve the table structure and constraints.
- Utilize the TRUNCATE TABLE statement:
- Empty the table named 表名.
- This will delete all data in the table and reset the storage space of the table, while keeping the structure and constraints of the table intact.
- the use of the DROP TABLE statement:
- Delete the table named 表名.
- This action will delete the entire table, including its structure, constraints, and data. Please note that this is a very dangerous operation and once executed, data cannot be recovered.
Choose the appropriate method based on the actual needs to ensure backing up important data before performing the deletion operation.
