Difference between DROP and TRUNCATE statement

Difference between DROP and TRUNCATE statement

When you use the drop statement it deletes the table’s row together with the table’s definition so all the relationships of that table with other tables will no longer be valid.

When you drop a table:
1. Table structure will be dropped
2. Relationship will be dropped
3. Integrity constraints will be dropped
4. Access privileges will also be dropped

On the other hand when we TRUNCATE a table delete all the rows from the table, the table structure remains the same, so you will not face any problems if we want insert new data into a sql table.

The Example of TRUNCATE the sql table employee.

TRUNCATE TABLE employee;

The Example of DROP the sql table employee.

DROP TABLE employee;
