I would suggest different way to do the same

-- Disable FOREIGN KEY and CHECK constraints for all tables in DB

EXEC sp_MSforeachtable @command1="ALTER TABLE ? NOCHECK CONSTRAINT ALL"

-- Truncate tables
TRUNCATE TABLE dbo.mytable1
TRUNCATE TABLE dbo.mytable2
...

-- Enable FOREIGN KEY and CHECK constraints for all tables in DB
EXEC sp_MSforeachtable @command1="ALTER TABLE ?CHECK CONSTRAINT ALL"
