Truncate table in SQL is used to remove all the rows from a table. It is similar to DELETE command but in truncate there is no where clause is used.
Here is the Syntax:
TRUNCATE TABLE table_name;
TRUNCATE TABLE EMPLYOEE TRUNCATE TABLE STUDENTS;
In truncate the process of rollback is not possible after the truncate table statement.Once you use the truncate command you can not retrive the content of the table.
