SQL Query

Structured Query Language is the full form of SQL. It is one of the standard languages to deal with the relational database. It is used to insert, update, delete, and search the records stored in a RDBMS. The relational databases are created and managed by using SQL.

You have the table T = (name, ssn, phone number) representing a person. Each name is uniquely identified by ssn, but the same name can have multiple phone numbers. Suppose you break the tables into two tables T1=(name, ssn) and T2= (name, phone number) a) What are the candidate keys of T, T1, and T2, respectively?
What is a key feature of fifth normal form? A key step in this normal form has every determinant in a table as a candidate key. Foreign keys are created in this normal form. This normal form has the tables broken down into as many tables as possible to avoid redundancy. This normal form resolves any multivalued dependencies.
There are three tables in this database (see image). Write MYSQL code for: (1) Create a trigger “insert_inventory” on table “Inventory”. The trigger is fired after a row is inserted in table “Inventory”. After a row is inserted in table “inventory”, the “itemid”, the insertion time, and the action is inserted in table “Inventory_history”. The action is set to ‘add an item’. The oldprice is set to null. Test your trigger by inserting a row into Inventory and displaying the contents of Inventory_history. (2) Create a trigger “change_quantity” on table “Transaction”. The trigger is fired after a row is inserted in table “Transaction”. After a row is inserted in table “Transaction”, update the “quantity” in table “Inventory”. For example, if 3 iWatch are sold, then the quantity of iWatch in table “Inventory” is decreased by 3. Test your trigger by inserting a row into Transaction and displaying the contents of the relevant row in Inventory. (3) Create a trigger “change_price” on table…
A table in third normal form is one which: A Has only one primary key. B Is linked to another table by means of a foreign key. C Have no repeating fields. - D Contains no non-key dependencies C
In this example, we will pretend that the student table in the university database is indexed by StudentID (the primary key), Major, Age, MaritalStatus, and HomeZipCode (all secondary keys). Let's pretend a university needed a list of students from the 45462 zip code who are either above the age of 25, married, and majoring in MIS or computer science OR who are under the age of 25 and majoring in computer engineering. Is there a way to use indexes to restrict results to to those entries that fulfill this condition?
Do the tables exhibit referential integrity? Answer yes or no, and then explain your answer. Write NA (Not Applicable) if the table does not have a foreign key.
How do primary key, candidate key, and superkey differ?
PLZ help with the following: IN SQL Let R (A, B, C) be a relation schema. What happens if we execute the following query? SELECT* FROM R WHERE A=D; Select one: a. We get an error. b. The query executes successfully but returns no tuples. c. The query returns all the tuples in R.
Answer the given question with a proper explanation and step-by-step solution. c. Create a relastionship: You need to add a new column called DeptID in the Employee table, it will be the foreign key in this table, it should be text data type and 5 characters in length. Make sure you enter one of the corresponding departmentID's values (i.e., ECON, MIS, and BUS) for this column in the Employee table for this newly created DeptId column that you have entered in the Department table previously. Then, use the Relationships tool under Database Tools to create a relationship between the Department Table and the Employee table, i.e., connecting the two tables together via the primary key (DepartmentID in Department Table) and foreign key pair (DeptID in the Employee Table and choose Enforce Referential Integrity to set the integrity contraint between the foreign key and primary key
A. Write SQL statements to create a table named STUDENT, with the following columns: StdID: character field of width 10, null is not allowed AdvID: character field of width 10, null is not allowed B. Given that the STUDENT table is created in part (a), write a SQL statement to insert a constraint to STUDENT table created in part (a) to designate StdID as the primary key (Do not recreate another STUDENT since it was already done in part a).
What happens if we don’t specify the WHERE clause in an SQL DELETE FROM statement? a) statement compilation causes a “Syntax error”, and the statement is not executed. b) all the tuples of the relaton are deleted. c) none of the tuples of the relation is deleted. d) all the tuples not satisfying the condition are deleted. e) none of the above. Which one(s) of the following is(are) procedural? a) Relational Algebra b) Relational Calculus c) Tuple Relational Calculus d) Domain Relational Calculus e) SQL f) (a) and (e) e) (b) and (e).
In Oracle database, if we have any field such as Job_Title field in any of our table then we can use DECODE function to sort the result based on our own numerical value.
