Solution
To implement the DeleteInactiveEmployees function, you would need to use SQL (Structured Query Language), which is a standard language for managing data held in a relational database management system. Here is a step-by-step guide on how to do it:
- First, you need to define the function. In SQL, you can create a function using the CREATE FUNCTION statement. However, SQL does not support deletion within a function, so we will create a stored procedure instead.
CREATE PROCEDURE DeleteInactiveEmployees(@salaryThreshold DECIMAL(10,2))
AS
BEGIN
- Next, you need to write the SQL query that will delete the records. You can use the DELETE statement to delete records in a table. You want to delete records where the Salary is below the salary threshold, so you would use a WHERE clause to specify this condition.
DELETE FROM Employee
WHERE Salary < @salaryThreshold;
- Then, to get the number of records deleted, you can use the @@ROWCOUNT function, which returns the number of rows affected by the last statement. You can store this value in a variable.
DECLARE @RecordsDeleted INT;
SET @RecordsDeleted = @@ROWCOUNT;
- Finally, you need to return the number of records deleted. In a stored procedure, you can do this using the SELECT statement.
SELECT @RecordsDeleted AS RecordsDeleted;
END
- To call this stored procedure, you would use the following command:
EXEC DeleteInactiveEmployees @salaryThreshold = [your_value_here];
Please replace [your_value_here] with the actual salary threshold you want to use.
Please note that this is a basic implementation and might need to be adjusted based on your actual database system and setup.
