- Write a stored procedure named updateUnitsOnOrder(). The updateUnitsOnOrder ()procedure should update the UnitsOnOrder field of those products that are discontinued. It should set the UnitsOnOrder field to 99 for those discontinued products. Hint: There is no need to use cursor processing for this stored procedure.PATHS is a table that contains information about paths on a number line. The structure of PATHS is as follows, where x1 and x2 represent that there is a path from Coordinate x1 to Coordinate x2 (You can't move from Coordinate x2 to Coordinate x1 ). NAME ΤΥΡE NULLABLE X1 INT FALSE X2 INT FALSE Problem Please write an SQL statement that returns the beginning and end point of each path in PATHS . Sort them by the value of the beginning point in ascending order. Constraints • In the case where a direct path from Coordinate a to Coordinate b is available, no path from Coordinate b to Coordinate a will be given. |x1-x2| = 1 • No path will overlap with one another. Example Suppose that PATHS is as follows: x1 x2 1 2 2 3 4 7 7 6 This table can be visualized as follows: START END END START 7 8. 9 Therefore, your SQL statement must return the following: start end 1 4 8 6Task 3: The Marketing team wants to collect emails of the users on InstantStay. However, the team needs a SQL statement to execute inside their programming environment. You need to create a statement that they can easily run the EXECUTE command to return a single column table containing the USER_EMAIL addresses. Task: Create a prepared statement for use with the EXECUTE command.

- Q2: Design Database for the following scenario and Write SQL queries. Create an ERD for the following scenario. Suppose there is a grocery store near your house. Following can be considered for ERD: A grocery store may have more than one employee. A grocery store has exactly one manager. The manager has one or more sales men working under him. Grocery store has more than one portion for the products. • Each product has a barcode, name, expired date. Many customers can busy many products, but each product is bought by only one customer. Each customer will get an invoice for his /her purchase. The bill invoice has an id.Database: CUSTOMER (CustomerID, LastName, FIrstName, Phone, EmailAddress) PURCHASE (InvoiceNumber, InvoiceDate, PreTaxAmount, CustomerID) PURCHASE_ITEM (InvoiceNumber, InvoiceLineNumber, Item Number, RetailPrice) ITEM (ItemNumber, ItemDesciption, Cost, ArtistLastName, ArtistFirstName) Write an SQL statement to show which cutomers bought which items, and include any items that have not been sold. Include CUSTOMER.LastName, CUSTOMER.FirstName, IvoiceNumber, InvoiceDate, ItemNumber, ItemDescription, ArtistLastName, and ArtistFirstName,. Use a join using JOIN ON syntax, and sort the results by ArtistLastName and ArtistFirstName in ascending order. Note that in Microsoft Access this require multiple queries. From Database Concepts 9th Ed.
