To create and use a stored procedure, you first need to create the stored procedure using the CREATE PROCEDURE statement, and then call the stored procedure using the EXECUTE statement.

Here is an example:

  1. Create a stored procedure:
CREATE PROCEDURE GetCustomers
AS
BEGIN
    SELECT * FROM Customers
END
  1. invoke a stored procedure:
EXECUTE GetCustomers

When calling a stored procedure, parameters can be passed to customize the query. For example:

  1. Create a stored procedure with parameters.
CREATE PROCEDURE GetCustomersByCountry
    @Country VARCHAR(50)
AS
BEGIN
    SELECT * FROM Customers WHERE Country = @Country
END
  1. Invoke a stored procedure with parameters.
EXECUTE GetCustomersByCountry 'USA'

This will retrieve all customer records with the country set to ‘USA’.

In stored procedures, additional SQL statements and logic can be used to perform more complex operations, such as inserting, updating, or deleting data. Conditional and loop statements like IF, WHILE, and CASE can be utilized.

When creating and using stored procedures, it is also possible to specify input parameters, output parameters, and return values. These parameters can be used to receive and return data, making the stored procedures more flexible and reusable.

Please note that to create and use stored procedures, you need to have the proper permissions.
