How to Clean a Database by Dropping Tables and Its Dependencies in SQL Server 2005

Cleaning a database by manually dropping tables, stored procedures, triggers, and constraints can be a tedious and time-consuming task. To simplify this process, SQL Server 2005 offers a powerful set of commands in a single statement.

This intricate script effectively removes non-system stored procedures, views, functions, foreign key constraints, primary key constraints, and tables, leaving the database clean and ready for further use.

Non-System Stored Procedures
A series of queries locates and drops non-system stored procedures using a loop and dynamic SQL. Each dropped procedure is printed for verification.

Views
Similar to stored procedures, views can be iteratively deleted using the same looping and dynamic SQL approach.

Functions
Built-in functions are classified as 'FN', 'IF', 'TF', 'FS', and 'FT'. The script identifies and drops these functions in a consistent manner.

Foreign Key Constraints
Foreign key constraints are crucial for maintaining data integrity. The script identifies each table with such constraints and employs another loop to dynamically drop them.

Primary Key Constraints
In a similar fashion, primary key constraints are detected and removed table by table using looping and dynamic SQL.

Tables
Finally, the script targets and drops tables, ensuring a complete cleanup of the database.

By executing this comprehensive script, you can efficiently clean your database, removing all tables, stored procedures, triggers, constraints, and dependencies in one concise SQL statement. This approach eliminates the need for manual processing and streamlines the database maintenance process.
