Truncate table when referenced by a FOREIGN KEY

If you try to truncate a table that is referenced by foreign key you usually get the following error:

Cannot truncate table 'TableName' because it is being referenced by a FOREIGN KEY constraint.

To avoid this error the easiest way to use DELETE without where clause and RESEED the identity:

DELETE FROM AccVoucher
DBCC CHECKIDENT (AccVoucher, RESEED, 0)
