Explanation of Solution
Creating a SEQUENCE:
The
Syntax:
CREATE SEQUENCE sequenceName
[INCREMENT BY value]
[START WITH value]
[{MAXVALUE value | NOMAXVALUE}]
[{MINVALUE value | NOMINVALUE}]
[{CYCLE | NOCYCLE}]
[{ORDER | NOORDER}]
[{CACHE value | NOCACHE}];
- The commands that are given in square brackets are optional.
- The commands given in curly brackets indicate that one of the two options can be used, but not both.
- INCREMENT BY specifies the interval between two sequential values.
- START WITH clause establishes the starting value for the sequence.
- MAXVALUE and MINVALUE clauses establish a minimum or maximum value for the sequence...

calculate_new_balance
Given a starting balance (a number), and a list of transaction tuples, calculate the final balance for an account. Transaction tuples are of the shape ("description", amount, "withdrawal") , or ("description", amount, "deposit"). The last entry in the tuple will be either "withdrawal" or "deposit". Every withdrawal decreases the balance of the account by the specified amount, and every deposit increases the balance. The return value is the new account balance, as a number. (which could be negative)
Sample calls should look like:
>>> calculate_new_balance(100, [("payday", 20, "deposit"), ("new shoes", 50, "withdrawal"), ("illicit winnings", 200, "deposit")])270>>> calculate_new_balance(100, [])100
Assignment Two:
We will write three procedures on our tables,
the first of which I
have provided as an example.
proclnsertPlayer takes one IN VARCHAR(16)
paramater and returns
an error code in the second SMALLINT (INOUT)
parameter.
The procedure checks the parameter and, if
there are no errors,
inserts the value into tblPlayers.

Sales Database:
Customers(custId, lastName, firstName, address, phone, creditLimit)
Orders(ordNumber, itemNumber, qtyOrdered.)
Items(itemNumber, itemName, price)
For the Sales Database referenced above, write the SQL command to create the LineItem table, assuming the Orders table and items table already exist.

Separately, we'd like to track the number of items in stock for each product. To do so we'll have a store and an inventory table. Stores have just an id and a name. Then, our inventory table should combine stores and products, listing how much of each product each store has in stock. a product_id (INTEGER) a store_id (INTEGER) a quantity (INTEGER) in stock Now we can insert some stores, products and inventory into our database. There are 2 stores -- one called NY and one called NJ. There are 2 products we are concerned with. Their names are sneakers, costing $220 (remember this is dollars!) and boots costing $350. Use any description for each that you'd like. NY has 4 sneakers in stock and 3 boots. NJ has 5 sneakers in stock and no boots. Insert the above data into the tables you have created.arrow_forward
- SQL: Create a SQL query that uses an uncorrelated subquery and no joins to display the descriptions for products provided by a vendor in area code 615. Remember, the main difference between a correlated subquery and uncorrelated subquery is that, in a correlated subquery, the inner query is dependent upon the outer query, while, with an uncorrelated query, the inner query does not depend upon the outer query. Instead, it runs just once. You should NOT use union, minus, or intersect in this query. The outer query will use the PRODUCT table and the inner query will use the VENDOR table [hint: you should have 9 records of output]. My code: select p_descript from product where (select v_areacode from vendor where v_areacode = '615' ; I am getting this error, problem is I can't see what is missing any assistance is appreciated.

Write a trigger that prohibits duplicate values except for nulls in the NoDupName column of the following table: CREATE TABLE TestUniqueNulls (RowID NoDupName varchar(20) int IDENTITY NOT NULL, NULL); (Note that you can’t do this by using a unique constraint because the constraint wouldn’t allow duplicate null values.) If an INSERT or UPDATE statement creates a duplicate value, roll back the statement and return an error message. Write a series of INSERT statements that tests that duplicate null values are allowed but duplicates of other values are not.arrow_forward
