To delete the records in a table , there are 2 ways .
1.Using the delete statement
2.using the truncate statement .
To delete the entire table drop statement is used .

Deleting a record from a table :
use the following statement.
delete from table_name
where column_name = some_value; .
The above statement deletes a single record at a time.

To delete all the records in a table the following statement is used.
delete * from table_name;

coming to the truncate statement , its like a delete statement without a where clause. the syntax is
Truncate table table_name.
It also removes all the records in the table.
In case of delete * from table_name and truncate table table_name all the records in the table is deleted but the table structure and its columns , constraints , indexes remain the same .

To remove the table from the database,use the drop table statement.
drop table table_name;
