Truncate All Tables from a SQL Server Database - TSQL Tutorial
Let's think about a database that we use for our ETL process and we call that database staging. We want to truncate all the tables in morning so those can be used for the daily process. Once way is to write our Truncate statement for each of the table but tables can be dropped or new tables can be created as well. We want to write a query that we can be use to Truncate all the tables from a database and we don't have to rewrite our Truncate statements. If the tables do not have Primary Key -Foreign Key relationship, we can use Truncate. But we often have tables which are referenced by other tables. We can not use Truncate statement for those tables. The only way to Truncate those tables is to drop the Foreign Key Constraint before Truncating and then Truncate and Recreate Relationship after that. The below Code can be used to Truncate all the tables from the database. If Tables will have the Pk-Fk relationship, The script will drop the Foreign Key Constraints first and then Truncate those tables and finally recreate the Foreign Key constraints. Before you run below Script, Make sure you are pointing to correct Database and Server! All the best with Truncating all the tables from a SQL Server Database.

Database trigger
A database trigger is procedural code that is automatically executed in response to certain events on a particular table or view in a database. The trigger is mostly used for maintaining the integrity of the information on the database. For example, when a new record is added to the employees table, new records should also be created in the tables of the taxes, vacations and salaries. This video is targeted to blind users.
