Filter products with a Discounted_Price greater than $95. display the ProductID, Product Name, Price, and Discounted Price.SQL: Add a table-level PRIMARY KEY constraint to the EMPLOYEE table using the ID column. The constraint should be named at creation. (Which means you'll need to drop the table, then recreate.) Create a PRIMARY KEY constraint on the DEPARTMENT table using the ID column. The constraint should be named at creation. (Which means you'll need to drop the table, then recreate.) Add a foreign key reference on the EMPLOYEE table that will ensure that the employee is not assigned to a nonexistent department. Confirm that the constraints were added by querying USER_CONSTRAINTS. Note the types and names of the constraints and include them in your statement comments. Display the object names and types from the USER_OBJECTS data dictionary view for EMPLOYEE and DEPARTMENT tables. You will want to format the columns for readability. Provide comments that include the new tables and indexes created. Modify the EMPLOYEE table by adding a SALARY column of NUMBER data type, precision 7. Confirm…

- Display product ID, product name, and category ID for products of the category(s) that the lowest price product belongs to.5. For each order, list the order number, quoted price and the item description, when the category is TOY.6. Use the inner join syntax to show the customer name and the matching order dates.Computer Science A study conducted by Netflix’s consumer relations department has revealed that customers are more likely to review horror and thriller movies during certain months of the year. To discourage seasonal variations in these movie ratings, Netflix has called for your help to analyze horror and thriller movie rating counts over the past 15 years. Your query should display each month of the year (name of the month not the number) and the total number of ratings given during that month. A third column titled “Promotion Recommendation” determines whether a promotion should be applied to increase the number of ratings given during that month. If a month has less than 2200 ratings the final column should display ‘10% discount promotion’, if between 2201 and 4500 then display ‘5% discount promotion’, and if more than 4500 ratings then output ‘No Promotion’. Order your results by months. Do not hardcode the current date. ORALCE CODE PLEASE.
