Difference between Truncate and Delete in SQL

Here we will see the first practical example

Suppose we have following table named as tbl_Countries

Now we will use the delete operation on given table


if we want delete specific record in table we have to use the Delete operations
with where clause

so as you have seen in above table you can delete specific row using Delete Operations

 if you want to delete all  records of the table just use the Truncate operation on your table.

so from the above example you can understand the clear difference between Truncate and Delete
