Stored Procedures vs Functions in SQL Server: Key Differences

When it comes to SQL Server, understanding the distinction between stored procedures and functions is essential for efficient database management. Let's delve into the differences:

Stored Procedures

• Definition: Stored Procedures are precompiled sets of one or more SQL statements that are stored in the database for subsequent execution.
• Usage: They can perform a series of operations and return zero or more values.
• Permissions: They can execute DML and DDL statements and call other stored procedures.

Functions

• Definition: Functions are program units that return a single value and can accept parameters.
• Usage: They are primarily used for computations within SQL statements.
• Permissions: They have limited permissions compared to stored procedures; for example, they cannot modify the database schema.

Ultimately, the choice between using a stored procedure or a function in SQL Server depends on the specific requirements of the task at hand. While stored procedures are versatile and can execute multiple SQL statements, functions are more suitable for calculations and returning specific values.

By distinguishing between stored procedures and functions, developers can optimize database performance and streamline data operations in SQL Server.
