assume that a database has a table named Stock, with thefollowing columns:Column Name TypeTrading_Symbol nchar(10)Company_Name nchar(25)Num_Shares intPurchase_Price moneySelling_Price money Write a Select statement that returns the Trading_Symbol column and the Num_ Shares column only from the rows where Selling_Price is greater than Purchase_ Price and Num_Shares is greater than 100. The results should be sorted by the Num_Shares column in ascending order.

A social media application stored information about each registered user in the table create table user (id int primary key auto_increment, name varchar(100) not null) A user can have many "friends" and can also be a "friend" to many other users. Specify how this relationship would be implemented by coding the create table statement(s) for the tables.

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

If we implement a queue using an array where we treat the array as if its two ends are "taped together", we call that a linear array. O True False

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. Documentation of errors Condition Error code No errors 1st param Null or zero len playerID taken 1 proclnsertGame will receive two IN VARCHAR(16) interpreted as

For this portion of the lab design the solution in the following manner: Create a table using a two-dimensional list that stores a Fahrenheit temperature and the equivalent Celsius temperature. Use the following range of Fahrenheit temperatures:Starting at -10 through 100 in increments of 10. Thus, the Fahrenheit temperatures will be:-10, 0, 10, 20, 30, 40, 50…and so on.Display the contents of the list.Similarly create tables/lists for the following, starting at 0 through 100 in increments of 10:Miles to kilometersGallons to litersPounds to kilogramsInches to centimetersDisplay the contents of each listSave the program as firstname_lastname_Lab7a.py where you will replace firstname and lastname with your actual first and last name.

1-Write the syntax to insert into a relational table called students the address column references an object table called addresses that was created using an address_type.  Other columns exist in the students table, but you are only inserting into the ones below. Aliases used should be the first letter of the table name, eg students would be s, addresses would be a Relational Table Name students attribute student_id attribute surname attribute address
