Computer Science This question is related to pl/SQL:- Using a Cursor in a Package In this assignment, you work with the sales tax computation because the Brewbean's lead programmer expects the rates and states applying the tax to undergo some changes. The tax rates are currently stored in packaged variables but need to be more dynamic to handle the expected changes. The lead programmer has asked you to develop a package that holds the tax rates by state in a packaged cursor. The BB TAX table is updated as needed to reflect which states are applying sales tax and at what rates. This package should contain a function that can receive a two-character state abbreviation (the shopper's state) as an argument, and it must be able to find a match in the cursor and return the correct tax rate. Use an anonymous block to test the function with the state value NC.

Write a PL/SQL Function that accepts 4 integers, 2 representing the homeTeamID and visitorTeamID, and the other 2 representing the score for each team during a game : htscore and vtscore The function will determine which team won the match and return the teamID of the winning team. You can achive this by comparing htscore > or < then vtscore.. if htscore is bigger then return hteamID or else return vteamID. If the game was a tie (the 2 scores are the same value) return a 0.

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.  ORA-00936: missing expression
