(HInt: It is easiest to use LIKE in this instance.) In addition, you are requested to replace either 'Man-Made' or 'Man Made' with the word 'Synthetic'. Only include ProductIDs between 1050 and 1060. Show the following in your answer: ProductID, ProductName, Composition, and the modified composition field as 'NewComposition'.

true/false INNER JOIN combines two relations. It takes the second relation, and appends it to the end of the first relation. In Corelated Subqueries, subquery is executed independent of the outer query: subquery is executed only once. SELECT * FROM sys.Relations displays information about all the user-defined relations within a database. Given GENDER and STUDENT relations, SELECT Gender, FName, LName FROM GENDER LEFT OUTER JOIN STUDENT ON STUDENT.GenderCode = GENDER.GenderCode ≡ SELECT Gender,FName, LName FROM STUDENT RIGHT OUTER JOIN GENDER ON STUDENT.GenderCode = GENDER.GenderCode The statements select RIGHT('I wish I had attended the practice hours', 9) and select…
Open the Missing Addresses query in Design view. Add a new column to determine if a customer does not have an address on file. If the customer’s Address is null, it should display Missing. If not, it should display nothing. Name the column AddressPresent. Add criteria of Missing to the column you just created, so only the customers missing an address display. Move the AddressPresent field so it appears between PhoneNumber and Address. Run the query. Ensure only customers with null Address fields display. Save and close the query.
