In the ever-evolving landscape of database management, the role of stored procedures in Microsoft SQL Server (MSSQL) for CRUD (Create, Read, Update, Delete) operations remains crucial. These procedures offer a structured way to interact with the database, ensuring that data manipulation is both efficient and secure.Create operations, as the name suggests, are used to insert new records into a database table. Read operations, on the other hand, are about retrieving data from the database. This can range from fetching a single record to extracting a complex set of data, often involving sorting and pagination. Stored procedures for reading data can significantly optimize performance, especially in large databases, by minimizing the data sent over the network and reducing server load.Stored procedures for updating records provide a secure way to modify data, often including checks to ensure that only valid data is saved and that unauthorized changes are prevented. Delete operations, though seemingly straightforward, carry the highest risk as they involve removing data from the database.
