Execute a SQL statement to add a check constraint to the field mode_of_payment with values ('D', 'R' or 'C") in order_db

The SQL statement below is used to select students with the last name "Smith". What is wrong with the statement? SELECT FirstName FROM Student WHERE LastName = Smith; The literal "Smith" must be surrounded by single quotes or double quotes. The WHERE clause should be removed. The last name "Smith" may not exist in the database.

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.

Trying to write SQL statements for these shown here and having issues with them working. Explanation on this would be appreciated.

Write SQL code for the following: Create a stored procedure "setRelocationFee" to set the relocation fee for a givenemployee. If the employee’s office is in San Francisco, the relocation fee is 10000ドル; ifthe employee’s office is in Boston, the relocation fee is 8000ドル; if the employee’s officeis in London, the relocation fee is 20000ドル; if the employee works in other offices, therelocation fee is 15000ドル. (see image for table structure) I am stuck for the part that I have to select employeeNumber and officeCode and set the relocationFee to be able to obtain the result but I do not know how. Bellow is what I have gotten. Delimiter| CREATE PROCEDURE setRealocationFee(IN EmployeeID INT(11), OUT realocationFee INT(5))

Create a function to insert a new product into an existing order, include the product id, unit price, quantity. The output of the function is the message to notify the calling program whether the update succeeded or not. note : Note: Sql code need not java don't waste my time by giving java code

database: sql Q1. Create the following tables: Carrier Attribute name Type Size Constraint carrierID Varchar2 10 Primary key carrierName Varchar2 100 NOT NULL Phone Varchar2 50 LIKE ‘+966%’ Range Varchar2 30 Value is either ‘International’ or ‘Local’ Review Attribute name Type Size Constraint ReviewID INT Primary key Stars INT NOT NULL Comment Varchar2 70 Name Varchar2 50 Default ’User’ CustomerID INT Foreign key references customers ProductID INT

True or False below: Given two relations named A and B, if we q-JOIN A and B, the maximum number of attributes in the result relation could be (the number of attributes of A) times(*) the number of attributes of B). * in an SQL SELECT statement means "all the tuples". In relational algebra, Cartesian Product (X) can be implemented using the q-JOIN operator. Cartesian Product ISA q-JOIN where q-condition always evaluates to true. SQL is based on Predicate Calculus. A query in SQL always specifies what should be included in the query result.

Below is "Book Order," the only table in library management system’s database. The design of "Book Order" as you may tell is in the zero normal formal form, you as the database designer want to convert the design into the third normal form. Order ID Special order date Customer ID Customer last name Customer First name Customer birth date Book ISBN1 Book Title 1 Book Author 1 Book publication year 1 Book ISBN2 Book Title 2 Book Author 2 Book publication year 2 Store ID Store name Store location Special order status Book Order(Order ID, Special order date, Customer ID, Customer last name, Customer First name, Customer birth date, Book ISBN1, Book Title 1, Book Author 1, Book publication year 1, Book ISBN2, Book Title 2, Book Author 2, Book publication year 2, Store ID, Store name, Store location, Special order status)

Express the following SQL code in Relational Algebra form.SELECT *FROM COURSEWHERE (COURSE.COLLEGE <> ’Business’OR COURSE.COLLEGE <> ’Engineering’)AND COURSE.CREDIT = ’U’;

My other instruction for SQL says: Create and test a stored procedure called checkin_transaction that processes a "checkin" transaction. When a book is checked in, the corresponding CHECKOUT record is updated to show the date it was checked in, and the Pat_ID attribute in the BOOK table is updated to NULL. The entire transaction (starting with START TRANSACTION; and ending with COMMIT;) should be in between the BEGIN and END statements of the stored procedure. You should be able to call the procedure with a statement like this, passing the values of the Book_Num, Pat_ID, and Check_In_Date to the procedure: CALL checkin_transaction(5243, 1170, ‘2017年04月30日’) Do you guys know how?

This assignment is aimed at building an understanding of how to improve performance within databases by taking advantage the computers hardware by modifying MS SQL settings Prerequisites: Completion of Assignment 1B, reading of Module Readings and Slides. Run the following query to understand how much Memory is currently in use in the database: SELECT physical_memory_in_use_kb/1024 AS sql_physical_memory_in_use_MB, large_page_allocations_kb/1024 AS sql_large_page_allocations_MB, locked_page_allocations_kb/1024 AS sql_locked_page_allocations_MB, virtual_address_space_reserved_kb/1024 AS sql_VAS_reserved_MB, virtual_address_space_committed_kb/1024 AS sql_VAS_committed_MB, virtual_address_space_available_kb/1024 AS sql_VAS_available_MB, page_fault_count AS sql_page_fault_count, memory_utilization_percentage AS sql_memory_utilization_percentage, process_physical_memory_low AS sql_process_physical_memory_low, process_virtual_memory_low AS...
